Pruvit Keto OS

Pruvit Keto-OS Review

Pruvit is a health and wellness company that primarily sells weight loss supplements through network marking.

About Pruvit

Pruvit just opened up to the public today (September 1st). We are still currently combing through all the information on their new website, but it does look impressive.

As soon as we known more about the program, we will let you know. Here is what we do know:

Pruvit Keto-OS

Keto-OS, which stands for “Ketone Operating System,” is the main product line that will be sold by Pruvit. It is essentially a ketone supplement in a drink formula that is sold by the tub or in individual packets. This is not to be mistaken with the Raspberry Ketones that you saw touted all over Facebook and online.

They have two versions; On The Go (OTG) and Tubs (KAN).

We were able to dig around and find the prices for Keto-OS:

— 15 servings (OTG) = $85
— 30 servings (OTG) = $160
— 30 servings (KAN) = $144
— 60 servings (KAN 30 + OTG 30) = $300
— 90 servings (KAN 30 + OTG 60) = $460
— VIP 75 servings (KAN 30 + OTG 45) = $350

These are the prices for the “Charged” and “Caffeine Free” versions. You can get this cheaper with Auto-ship as well. Here are the prices for using Autoship:

— 15 servings (OTG) = $76
— 30 servings (OTG) = $144
— 30 servings (KAN) = $133
— 60 servings (KAN 30 + OTG 30) = $255
— 90 servings (KAN 30 + OTG 60) = $368
— VIP 75 servings (KAN 30 + OTG 45) = $350

You can also get a Pruvit KETO-OS Sample Kit on their website if you are just wanted to try it.

When we contacted Pruvit for a quote about their product and what it does, here is what they said:

Keto-OS is your “ketone operating system” it is the First Therapeutic Ketone Supplement on the market. The proprietary blend is owned by Prüvit and is Dr. Approved, Lab Tested, University backed and the technology in Keto-OS is patent pending, developed by one of the most world renown Dr.’s and experts on Ketosis. Prüvit was the first company approved by University of South Florida to acquire the sub-license rights to use this patent pending technology. It is a powder that you mix with 8=10 oz. of water. Within 15-30 minutes it puts your body into Ketosis. Prüvit owns the worldwide rights to Keto-OS. Keto-OS has a certificate of analysis for purity, consistence and efficacy.

Ketone supplements are commonly used for weight loss because ketones are created in the body when the body uses fat instead of glucose for energy. This is a condition known as ketosis, and it is said to be the most effective way to lose weight.


Pruvit just released more information about their product. We can finally start to better understand what Keto-OS can do for us.

Is Keto-OS Safe?

While we haven't seen any actual clinical trials on the Pruvit Keto-OS product itself, there is a ton of research dealing with ketones. As you will see, we have linked to some below. As with any supplement, you should always consult with your doctor, but they mention two things in particular with their supplement; Hypersensitivity to salt or have any risk of kidney stones, that you should really consult your doctor about before taking.

It is also suggested that you should start with a smaller dose and work up to one full serving so that you avoid any gastro-intestinal discomforts.

We did just come across this supplement fact sheet for Pruvit Keto-OS. It still doesn’t give us full insight into what is in the proprietary blend, but at least we are starting to see what is in the product, and soon, the company.

What is not pictured is the Ingredients: MCT Powder, Beta Hydroxybutyrate, Natural Flavor, Malic Acid, Stevia, and Caffeine

This is from the KETO-OS Charged version.

Pruvit has just put out a full Pruvit KETO-OS FAQ on their product. This should answer a lot of questions about the product.

Research On The Ingredients

Here is a list of research articles and studies that dive heavily into Ketones and the other ingredients in Keto-os.

Dietary Ketosis Enhances Memory In Mild Cognitive Impairment
The Effects of Beta-Hydroxybutyrate on Cognition
Ketones Suppress Brain Glucose Consumption
Neuroprotective And Disease-modifying Effects Of The Ketogenic Diet
Clinical Review: Ketones And Brain Injury
Nutrition and Traumatic Brain Injury
Ketogenic Diets And Physical Performance
Treatment Of Diabetes And Diabetic Complications With A Ketogenic Diet
Long-term Effects Of A Ketogenic Diet In Obese Patients
Effects Of A Ketogenic Diet On Tumor Metabolism

As you can see, there are a lot of research articles out there on the topic. So it is apparent that Ketones are important. That gives us hope that their product may actually be significant.

We asked Pruvit why someone would take their supplement:

Supplementing with exogenous ketones allows you to experience ketosis – the benefits of elevated blood ketone levels, without having to follow such a restrictive ketogenic diet, or super low carb diet, which is often difficult for some people to adhere to. Optimize your human potential.

Pruvit MLM

What we do know is that Pruvit will operate as a network marketing company. In other words, the company plans on recruiting new distributors into the program to sell their products.

As of right now, we don’t know much about the compensation plan other than the fact it follows pretty much other compensation plan. Your two most basic ways to earn are through selling Pruvit products to customers and by referring new distributors. It looks like there are multiple ways to earn money within the company. But we will leave that to other sites to break down for you. If you wish to take a look at the opportunity side of things, you can view their: Pruformance Rewards Gameplan pdf.

Any Guarantees?

It does look like if you aren't satisfied with their product they will off you a full refund (minus the cost of shipping) as long as you contact Pruvit within 3 months of your purchase. They do not require a return of the product itself if you only order a 1 tub pack. But anything beyond that they would require you return the product.

That is promising from a MLM type supplement company.

Should You Try to Join Pruvit?

Right now, (as of today) the company just opened up to the public. Allowing members to share the products with customers or even other people who are looking to promote the product.

While it is probably best to do your own research on Pruvit, it is starting to take shape and I like the look. If you’re actually trying to use the products, then we recommend you look at the research provided above on ketones and a ketogenic diet based products to help you lose weight. Just remember this isn't Raspberry Ketones, which all started when Doctor Oz talked about their weight loss properties on his TV Show. This is something that has a lot of research to back up its claims.

While this is just a brand new product/opportunity, we are hopeful and expect this company to be around for a long while. There is quiet a bit of research on the topic, so that gives us hope that this could be a significant company.

One thing that the company did reveal, is that you can see the changes in you body in 59 minutes or less. You can pick up a Ketone Urinalysis test kit to actually see that your body is absorbing the ketones. You simply pee on the test strip before taking their supplement, see the results, then drink and then retest again 59 minutes later.

Being able to see the results in an hour or less is encouraging.

But if you want to learn more about Pruvit, you can do so by going to their official website.

The last update from the company said that orders are flying in so fast that they are having to put a restriction on orders daily so that they can keep up with demand. They don't want to get them selves in a hole with customers (like Total Life Changes IASO Tea). They have capped sales at $100,000 per day which they are hitting in the afternoons, if not earlier. And they re-open the following day for orders.

Their VIP packages (that give you extra product for sharing and automatically give you Level 5 Rank in the company (MLM Side) for 1 year, accelerated “Go Fast Bonus” for 4 weeks, VIP seating at events, and private tastings of new products) were scheduled to be shut off Sept 1st, but with them putting the daily limit, they are giving people a chance to continue to purchase by extending that deadline. So if that is something that interests you, I would do that now.


  1. I enjoy the comments because I’ve read them before, just switch out the product name and change to Herbalife, Juice+, Heartbar, and on and on. First, check with your doctor before doing anything to put your body in ketosis because it it can ruin your kidneys. The ketosis diet was popular as an offshoot of the Adkins, then health problems were seen. But, if you survive it, it can be a good way to lose weight. But much like eating veggies is good but Juice+ isn’t a veggie, ketosis can help you lose weight but there is no proof that this product puts you in ketosis, which required massive intakes of fat. You will feel a boost of energy from the caffeine and salt. Another key ingredient is L-arginine, which has been included in some “heart healthy” MLM’s since the 80’s. There is some proof it can be helpful, but you can take it in much cheaper forms. And, high use of it can cause cold sores(pretty sure you won’t see that noted on the label).

  2. I see no post on pre menopause and this product ? Weight is like a yo-yo even though diet is low carb and low protein and some fat?

      • Yes please share your journey with this product since I am really not convinced that this will help with weight lost without me exercising 3 or more hours a day/ night ….

  3. I’m a non-believer (and I’ve tried it).

    Follow my logic:

    Step 1: A carb-restricted diet causes hormones to breadown
    fatty acids in stored fat cells.

    Step 2: The fatty acids get pushed to the liver where (by
    way of enzymes) they break down further into ketone bodies.

    Step 3: The ketone bodies jump into the blood and get pushed
    to various areas of the body that need it (energy).

    Step 4: All leftover (un-needed) ketone bodies are shoveled
    into your kidneys to be sent out of the body via your urine.

    Since KETO OS is ADDING ketones to the body (opposed to
    forcing the body to PRODUCE them), I think its fair to say that taking KETO OS
    starts you off in STEP 3. If that’s accurate, then STEP 1 & 2 have not
    occurred, which means the breakdown of fatty acids haven’t occurred. That would
    be PROBLEMATIC for those using this product in hopes of burning fat/forcing fat
    oxidation. However, a case could be made that using KETO OS long enough will
    trick the brain into become keto-adapted, where the brain decides it will
    switch its energy preference from glucose to ketones. I think this might be
    able to happen by the continuous presence of ketone bodies in the blood (i.e.
    the continuous use of KETO OS) Yet, I’m unsure if that’s the case.

    So, in my opinion, the follow is either true or likely:

    1. Taking KETO OS will NOT provide any immediate fat loss

    2. Taking KETO OS can provide energy during workouts.

    3. Fat loss benefits will only occur if the continuous
    presence of ketone bodies in the blood force the brain to become keto-adapted.
    Extended use (maybe weeks or months) of KETO OS may POSSIBLY trick the brain
    into become keto-adapted.

    4. KETO OS may suppress hunger, which may directly result in
    preventing additional weigh gain. This means you may stop from gaining more
    weight, but doesn’t mean you will lose your current weight.

    Is there anyone out there ready to use biochemistry to suggest that I’m wrong?


    • A well written reply.
      The video clip used in the promotion of this product is full of incorrect science and physiology. Your body readily uses glucose and stored glycogen, but it is always using a low level of fat for energy. It values amino acids from proteins so they are used last for energy; they may be used when there is no glucose.
      It does not take weeks or months go go into ketosis; go without food for a day or two and you will soon be going through your body fat and producing ketones.
      The way to energy loss is by using up your own fat supplies to produce the ketosis.

    • I’m not in biochemistry but I completely agree. How does drinking this supplement benefit me if my goal is to take off the eXtra 30 pounds I’ve been carrying for the past 16 months?

      • This is NOT a weight loss product! It is ketones! NOT a diet! Just ketones! Personally, I have had great results in the 50 days I have been on it and I eat very low carbs and sugars now! I give it to my 16 month old baby as well!

    • I’ve taken it for 22 days, and CAN confirm most of what you’ve said.
      My start weight and today’s weight BOTH 186.2 lbs, BF loss of only 0.7 % (23.1 …22.4) well with the normal daily fluctuation.
      I think this is a MLM thing, even though some people have benefited, I have not.
      I have not seen any positive energy increase, and in fact, have been feeling worse the past week.

  4. Will you please address the effect this has on people with hypertension? When I take a whole packet, I feel like I am speeding and my blood pressure increases.

    • Hi Chukwuemeka Amadi,

      I am currently a distributor & would be happy to help with any questions, help you order, & get you set up as a distributor. Everyone has their own story, but here’s mine. I started taking KETO//OS in February. I started taking this not for the “weight loss”, but because although I’m only 42, I felt like an 80 year old woman. I was having chronic pain throughout my body & despite the doctors visits & pain killers, nothing worked. I read about how a ketogenic diet promotes a decrease in inflammation in your body so I decided to try it. Within an hour of consuming the drink I noticed a significant decrease in the amount of pain. Within 3 days, my pain was completely gone & even though I was not taking the product to lose pounds, within a week I had lost 10 pounds of fat. Unfortunately I hit a rough patch financially & was forced to stop taking the product. I again started feeling a lot of pain so finally, 2 weeks ago, my hubby surprised me with more product. I began taking it again & today I am pain free & have lost 12 pounds of fat. And I feel like I’m in my 20s again. This stuff is no joke. I have included the link below for you to read more about the product & it’s benefits. I would also encourage you to do your own research on ketosis & it’s benefits outside of the Pruvit website. Feel free to call or text me at 918-639-2416 if you would like to discuss, order, or become a member yourself. I hope this has helped!

      Have a great day!

      • It is NEVER a good ideal to lose 10#’s in a week. #2 the laws of physics would say that of a 10# loss on a keto diet, would mostly be water loss.
        Just keeping it real here.

      • But you are now selling it; don’t you have a conflict of interest in promoting its “positive benefits”…many of which could have eventuated through mind over matter and other things you did at the same time.
        This is why we have controlled clinical trials, not “this stuff is great, it worked for me…and hey, now I am selling it to make money.”

  5. Good information. Took my first 1/2 packet yesterday. Went to red lobster for lunch (before I went I Googled: what to eat at red lobster that is on the ketosis diet.) Found a lot of feedback on the subject. Then for a late night dessert, I had one of my south beach diet recipes of ricotta and cream cheese with stevia and almond flavoring. Super low carb and delicious. Well, I lost a whole pound yesterday! Totally surprised, because that never happens when I eat there. So, super excited to see where this leads me. Wish me luck.

    • This is Shelly again. Day 6 and I have lost 5.6 lbs. I don’t know about you, but I have never lost this much weight in 6 days, unless I had the flu. Lol. Bought a book called “Bacon and Butter ” At Barnes and Noble. Great Ketogenic recipes. Will check in again next week. Wish me luck.

  6. Hello, i’m interested in becoming a distributor. Can someone contact me, I would like to be on a good and supportive team. From Ontario, Canada

    • Hey Jason,
      So far the company only exists in US, Canada and Australia.
      I’m in Denmark so I look forward to it opening here, too.
      Good Luck.

    • Hi Jason,
      I’ve find a way to get the Keto OS shipped to Denmark. If you are interested, I think I can help you get some shipped to your country as well.
      Let me know.

      Have a nice day.

  7. I use Keto/os and I have seen many benefits personally from it. I truly feel better, my skin looks so much better and i have lost 35 lbs with out any work outs, this did not happen the first week i started to notice my changes about 2 1/2 weeks, just a little bit more information I’m recovering from 3 pelvic fractures and i’m not able to work out at this time so my results should get better when i start working out, so i do have intentions adding a work out. i ask that you please research the product and its benefits. let me state before any one gets upset that I started in march and decided after taking it a few months that it was going to be a great product and help many people so i choose to become a promoter.

    • How long will I have to wait until I experience ketosis? I have been on the powder drink for four days – and have GAINED a pound and feel NO effects, see no changes, and have been on a low carb – basically South Beach – diet little over over a week-having lost 3 pounds before beginning this – and STILL gaining a pound. This makes NO sense to me. I completely stopped all alcohol, all high carb foods, sugar, ANY drinks with calories, while keeping carbs at a minimum – below 20 or less.

      • Pam,

        I’m just following up with you on your progress. I wanted to remind you that while eating low carb will definitely help the process, it’s also important to eat HIGH FAT. While taking KETO//OS, your body will be in a state of Ketosis within 59 minutes of consuming the product. But by definition, Ketosis is characterized by raised levels of ketone bodies in the body, associated with abnormal fat metabolis. That means your body NEEDS fat to metabolize. My diet consists of under 15g of carbs per day, moderate protein, & extremely HIGH FAT! I have lost 12 pounds of fat in 2 weeks. I’d be happy to help with any questions you may have.

        Have a great day!


  8. I have been taking keto os 3.0 chocolate swirl for 2 days. I have gained a pound. I Don’t feel more energetic or more clear headed. I dont expect things to happen over night but I seems after reading review from others that it does. I am going to stick with it but wondering at what point I should expect to see results.

    • Tulip,
      I experienced the same. However, I did switch it up a little with the orange and on the 4th day I noticed a great difference and not on the scale but in my clothes. I recall when I did the atkins diet this was the same thing that happened. I noticed my clothes were loose but the scale didn’t move much. I would suggest that you try to change it up or consider MAX.

      • I have been using the orange dream for 15 days accompanied with a low carb diet, only water to drink and lots of it. Gained 5 lbs. I would lose a couple lbs and then gain 5

  9. So, as with any weight loss program, it’s usually been found that people gain the weight back back and then some after they stop whatever supplement? I’m just curious, as a nurse, as to what the long term is with this product? Lifestyle, diet and healthy changes are what the goals are (should be) but can one afford to both financially and physically take this supplement for ‘years to come’? I’m curious if this is a ‘quick fix’ solution to a ‘quick fix’ population?
    Wouldn’t going ‘ital’ be a better choice?

    • I must agree with you this one. My health insurance have a weight loss program at a discount with meal replacements,nutritional counseling and water aerobics all at a discount. I took advantage and loss 60lbs on the program in a year (2003). I tried to go back to the program, gained some weight back, and in review of my benefit packet I am only allowed this program “once in a lifetime” I can never use this again. Now if I was a smoker or a drug addict the programs are on going, people can reapply for treatment unlimited but a fat person only gets on chance at making a difference. There is money to be made off being fat; the medical industrial really don’t want to help us. This product seems good on paper. I do not know anyone who has used it. I would love to have a sample. Cant afford it!!!

    • If you want permanent weight/fat loss and to enjoy the health benefits of being in ketosis then you will need to eat a diet consistent with keeping you in ketosis. No quick fix diet will ever give you long term weight loss. You need to permanently change your diet forever. That means minimal carbs and the majority of your food intake as fat. If you can’t or won’t make that adjustment then quick fix supplements are a waste of money.

    • I understand your concerns with the thought that it could be a quick fix. My husband has 90lbs over the last 4 years and I have lost 50lbs. We havent gained back the weight and feel great. Sometimes products are worth a try. My husband and I did and it worked. Do your research and if it feels right to you give a try.

    • The goal for any weight loss product is not a quick fix, it is to motivate you to become healthier, this by selecting a healthier diet as well as an exercise regiment.

  10. Every one needs to click onto Pruvit-OS-FAQ listed above , and visit all (4) sites and learn not only the good side of this product, but the dark sides not listed on this page.

  11. Everyday people do not know how dangerous high sodium can be. As with the woman with diabetes 11, and high blood pressure. She did not think about the sodium raising her BP so much, or the effect of high ketones in a Diabetic. When the body can not process the sugar, it starts burning muscle not fat, & starts throwing off ketones. I suggest anyone with a illness like diabetes, high blood pressure, etc, or with a multitude of medical diseases, and take a large list of prescription medications, check with “Physician before starting any of this”. In the notes above comments, it said the high salt content has put people in the hospital. I myself am allergic to many of the compounds the companies use to hold the medications together, and not the actual medication itself. You find this out when your pharmacy starts going with different companies for cheaper generic drugs. I had them go back to the original company and special order the generic I took for years, no more problems. I am checking this supplement out because two family members are trying it, and a third one (which is diabetic) wants try it. They suggested I try it, since the first two are having good results at the moment after one week. They are both young, but one does have medical issues.My big concern is for the diabetic. What does the manufacturer suggest for diabetics, and chronic pain.

  12. I’m allergic to contrast iodine, like for ct scans. I’ve been told to avoid shellfish because of this. I don’t like shellfish so I haven’t ‘tested’ this theory. I’m curious if I’d be allergic to the drink?

  13. Supplementing medium chain triglycerides (MCT) alone does not put your body into ketosis. Supplementing MCT’s like coconut oil, for example, will elevate ketones in your blood because the liver converts MCT’s to ketone bodies. In ketosis, your body converts (“burns”) glycogen for energy due to the absence of glucose. This process produces ketone bodies that the brain will use for energy. It to will cause an elevation in blood ketones. The point: supplementing ketones will not cause glycogen metabolism or fat burning. Save your money. Take a spoonful or two of coconut oil daily, it’s less expensive and better for you….still won’t burn off any fat stores, but at least you’ll save some $$!

    • I’ve met a lot of resistance when comparing this product to mct oil. After reading what this product does, I really don’t understand why someone would shell out the cash for this when it sounds like MCT does the same thing. You can also take MCT oil and read positive for ketones within an hour. It converts into ketones to be burned for energy. I’m looking for a better explanation for why this product is necessary beyond it just being “science”.

  14. Just to put this out there…

    The ACTUAL reason the salt content is so high isn’t for the BS reason they state. The real reason is they stole this idea from an existing company. That exiting company that developed this technology and the original formula used 4 different mineral types. Pruvit can’t get their hands on the other two mineral types because the original company that developed the technology owns the production rights to the other two mineral types. Its the 4 mineral types together that make the actual product that works the way it should. Pruvit’s high salt content is their way of bandaging a broken formula that doesn’t work nearly as good as the original companies formula that developed this technology.

    Dig deep enough and you will find that several folks have been hospitalized from taking this drink due to the high salt content.

    Pruvit rushed to market with a formula they schemed from the original developer just to make a few bucks.

    The original creator of this technology is about to release the actual formula that works (provably….once you compare Pruvit’s to the actual formula it’s night and day). So don’t get too in bed with Pruvit. Their days are numbered.

    • Actually the company you are most likely talking about is very corrupt company. They keep trying different products and striking out. They did the power strip and lied to people. They then was going to do the ketosis deal and backed out on it. Then when another company was going to do it, they tried to deal under the table and make a deal. Which back fired on them. Good luck in what you do. But you really need to look deeper into that company you are with.

    • What product are you referring to as the “other” one? I have seen pretty good results with my first tub of Keto OS, but if there is something better or cheaper I’d like to try it.

  15. Whats the best Pruvitnow team to sign up with? I want a sponsor that can take some time help build a team. I been reading the reviews and researching ketones and I’m excited to get started.

  16. KETO//OS is a “First of its Kind” product. Prüvit’s proprietary formula has been researched, tested, and doctor approved. It is the first natural consumer product on the market to provide elevated blood ketone levels to the body.

    • Jesse, have you found a Prüvit team? If not, we’d love to visit with you, we began as first level to the launch team originally put in place the end of May 2015, before we went live Sept. 1, 2015. We have a strong team and you would come in second line to the top.

      Thank you!

  17. hi everyone,

    like many people here, i have tried putting the body in ketosis by cutting carbs. it is very difficult to do, and so i am willing to try this product, which on paper looks good and right. i bought 30 packs and just started, so i cannot tell if this product really works or not. but so far, i experienced the same as some people mentioned here. the urine test show strong ketones level after 45 mins, but the level drop after a few hours. i have not seen any weight loss yet… i personally don’t mind if this product only provide temporary effect, as long as i am burning fat within that window of time. this case i may only drink it before exercise, and keep cutting as much carbs as possible with a low calorie diet. so could anyone have proper source that show either we will burn fat during that period or we are just being fooled by inputting ketones into our body?

  18. Not sure why someone on this thread is saying it is not going to help with weight loss goals. My 78 year old dad has lost 9lbs and countless inches taking it. He has not changed his diet and still eats carbs and sugar. My sister-in-law has lost 12lbs and dropped 2 sizes. I personally have lost 3lbs but 5 inches off my waist. I could go on and on about the countless people who have improved their overall health with Keto os.

  19. Why isn’t the company selling this product at retail locations, or to physicians? Why the multi- level marketing scheme? I am very uncomfortable with the way they are promoting and selling. I takes me think that this is a “fad” product. Can anyone explain?

    • How else would you market the supplement that requires an understanding of what it offers? Why not pay the people who use it, understand it, and share it?

      • For the same reason I don’t ask my neighbor to tune-up my car when there is a problem. He’s not an auto mechanic and those people aren’t doctors. Although he does “use” a car, “understands” how to drive it, and shares his with me if mine is in the shop.

    • Multi level marketing is not a scheme. Do your research. It simply takes out the high cost dollars of advertising and store fronts and allows us to buy product cheaper and put money in our pockets while doing so. A scheme would be where you have no product!

  20. I have been suffering from major Kidney stones!!!!! I also only stayed in Ketosis for perhaps an hour. Weight loss was minimal. You’ll accomplish the same thing just cutting out the carbs and naturally going into Ketosis. Keep eating veggies – berries and exercise – there is not magic drink. Dr. said never to take it again.

    • How long have you used Keto//OS? Have you had kidney stones in the past? Also, know that Keto//OS is not for WEIGHT loss, but FAT loss.

    • Keto//OS did not cause kidney stones lol, do the research yourself, not what the product does but what the ingredients do. Man you probably had stones before taking this. thousands of us take it and I haven’t had a problem with my kidneys, in fact after two weeks being on this my blood results got better and I’ve lost at least 11lbs. Yes I’m also on the keto diet but no where as stricked as you should. I have at least 2 maybe 3 cheat days a week where i’ll go over 100grams of carbs or more, yes drinking a lot of water and being on the diet some what will help you lose weight but this product also helps with my asthma and inflammatory, also I have tons of pure energy and my alertness and mental clarity is way better. There isn’t a magic drink or supplement out here I know that but this helped me succeed in my diet and get away from sodas by far. I’m a form believer in this stuff. and no I’m not with the company lol. Just saying do the research before blaming something. this doesn’t have bad ingredients in it!!!

      • Brian, here is some research for you straight from Pruvit Keto/OS website;

        Kidney stones are a known potential side effect of the ketogenic diet. Exogenous ketone supplements are a novel technology, so it is currently unknown if it could cause a similar problem, but it is possible. Clinically, potassium citrate is used to help decrease the risk of kidney stones (See here:, including those that occur with the ketogenic diet. Potassium citrate is available commercially; however, as always, consumers should consult with their physicians before taking any supplements. Found here:

  21. I have a serious question about this product. A friend of mine who is a professional bodybuilder sent me 4 packets of keto//os. I am an athlete who has done masters bodybuilding. Since I am an experienced dieter who fell off the wagon when my father was hospitalized, I was elated to find this product. I am very experienced with the ketogenic lifestyle, so the energy, stomach calming, mood enhancement I felt with my friends first 4 sample packets was exciting. I bought some on amazon and ebay because of the price difference (since hospital bills and being retired tapped me out). Right away my stomach issues and bloat returned in spite of a ketogenic diet with the main carb source being greens, tomatoes, and other vegetables. I did not use my keto stix right away, because the samples and my diet threw me into ketosis within an hour. However, feeling crappy today on my first packet with barely a trace showing, I took another for the first time. Two hours later, the stix showed slightly more than a trace. I had noticed the powder has a slightly cheesy smell mixed with the orange. The samples had a distinct orange cream smell and taste. I could guzzle the samples, but my purchased packets did not taste yummy like the samples did. I am actually going to buy more ketostix, drink more water, and seriously check these out. It is almost like the samples are the real deal, but the purchased packets are a different batch which has been cut (as the drug merchants say). I got a very upset stomach in the gym tonight while with my trainer, and I had to cut my session short. I cannot understand how my samples could be so different from what I purchased. I do not like being ripped off, being on a fixed income and all. The samples were definitely not a placebo effect. I am far too experienced to fall for that. They truly did work. I want to know if someone is making knockoff look alikes, or is this company doing some hankypanky like a hit and run process. If that is what they are doing, some very fine professionals are going to be hurt when the shtf. Has anyone else had this experience? I really want this stuff to work. I was a big cheerleader after taking the samples, and my upset stomach felt normal again. Please reply.

    • Gretchen,

      Thanks for leaving a comment. – You definitely were not censored, we just manually approve all comments. And as far as your experience with the sample vs your own purchase, there is a chance that you had two different formulas. I believe Pruvit is currently on version 3.0. So it is possible that you had a sample of v1 or v2 and bought v3 or even had a sample of v3 but actually were shipped a set of the v1/2. I believe in each version they were tweaking the amount of salt.

      So maybe that is the difference. It is hard to tell.

      • How can a customer tell if there is no lot number or indication of what version is being taken? There is no difference in packaging. This borders on unethical. I want the one that works. If I spend another $250 and get stuck with the wrong one again, I am even going to be angrier.

        • Gretchen,

          With how fast we hear they are moving through product, I would be surprised if what I had said was the truth. I would imagine all new shipments are the current version since they are shipping them out as fast as the product is being made. And I did a little digging last night. It appears they are still on v2 currently but as of early Oct they were still “testing and perfecting” version 3 and 4.

          So I am uncertain why you would have felt differently with the two packs. Were the sample packs the same as what you ordered – in size?

          • I’m wondering if because she bought it on Amazon and Ebay, she might have gotten a fake product. I have bought brand name products on Ebay before and when I received I noticed almost right away that the product was a fake. Amazon deal with sellers all over the world. I wouldn’t be surprised if the product Gretchen received was a copy, not the original.

        • Gretchen, I also have been researching Pruvit Keto/OS, I also found that on eBay it can be purchased for less but I also found that some ebay sellers are selling “old”(but do not expire for 1+ year) versions of these products, so you will want to look very closely and even ask the seller questions if it is not clear on their listing. I have found that the packaging for the different versions DO have either slight packaging changes to total packaging change (this is how I actually found out there were different versions, I noticed the packaging looked a little or a lot different from the packaging on their website). The newest Versions (I found on their website) are Version 2.1 (the versions are also located on their packaging, so look for this as well) “Charged” in the Orange flavor both caffeine and Caffeine Free and Version 3.0 “Charged” in their new Choc. flavor only. Hope this helps.

  22. If you want to check out all of the companies info you can find it but there is also tons of ketone research available online and thru more scientific and reliable sources like the NIH website, Ncbi information, and clinical . lots of research to sort through but its all interesting.

  23. Hello Everyone:
    When the human body is in ” The State of Ketosis” a by product is the taste of acetone in your mouth.
    When that taste appears one knows for sure they are in the state of ketsosi. Toothpaste and mouthwash will not get rid if it. This is when the human body starts burning a lot of fat.
    Good luck to all.

  24. Just so everyone understands… With this product, you are not IN Ketosis, you are simply ingesting a product that puts ketones or ketone byproducts in your urine… the only way to lose weight is to create your own ketones by burning FAT…. this can only be achieved by eating a low carb diet.

    • Scott, you’re correct ! ! !
      Please ! Not another MLM company touting wonderful things about ketosis ! This product puts ketones in the blood-stream, however does NOTHING to put your body into metabolic ketosis ! Keeping your blood-sugar (glucose) stable and in the lower range will naturally cause your body to burn fat. This product does NOT do that ! ONLY a low-CARB diet can do that, as the body then has to actually change the way it manufactures energy. It starts more efficiently burning fat instead of glucose, so the trick is actually lowering your total carb load every day ! As your body shifts to burning more fat, your natural ketones will increase. Try doing 20grams of carbs/meal no more than 60grams/day and you’ll see rather quickly how you can lose weight ! For MOST folks (about 70%) this works ! Why spend all that money to do something that your body does naturally given the proper food. The other ingredients may make you FEEL emotionally better, however have basically nothing to do with weight loss… If you’re a doubter, just ask them exactly how this products puts your body into ketosis ! All the research above touts a ketogenic DIET, not a ketogenic product !

      • Absolutely, the best way to lose weight is to follow this guidance and eat real food! the answer to health is not supplements and more synthetic food. We need to eat healthy, not manufactured food.

  25. Just finished my 15 day supply. I was in kerosis when I started thru reducing carbs and practically eliminating sugar. I have not had any of the “wonderful feelings” that everyone has been raving about. Eating a high amount of fat has been difficult. I have not lost one ounce! A friend said its not what you lose its how you feel!

    I think the product does not work for everyone.

    • if you read the packet, this is not a weight-loss supplement (even though they seem to market it as such) “Keto//os is not a medical treatment, medicine or weightloss supplement, it is an exogenous ketone product that elevates ketone levels in the blood”

      This product is fuel. It helps fuel intense activity that your body’s conversion of fat into ketone bodies cannot keep up with. If you take this product and are not an active athelete burning 4000+ calories a day, you will not mobilize and convert fat cells (lose weight) because your bloodstream already has more fuel than it is using (compliments of keto//os). If you are running 5 miles, ketosis will likely not adequately support intense activity for that period and you will become exhausted after 1-2 miles. This is accomodated with having some carbs, which could screw with your ketosis if you carb load and miss a workout or get injured, etc. in which case keto//os would be a beneficial alternate fuel boost before this (or similarly) intense activity.

      this article is pretty good, if not too in-depth for a non-geek.

      if you want to lose weight with low exercise (1-2 mile walk per day, no hills… the more the better but trust me I understand wanting to maximize benefit while minimizing effort for times sake) you will never exceed the fat-burning zone (moderate heartrate) and keto//os is counter-productive. Ketosis and 1800-2500 calories a day with about 55-70g protein (excess protein is converted to carbs)

    • this product does not put your body into ketosis. The length of time that the ketones (fuel) remain in your bloodstream depend on how much exercise you perform.

  26. I’ve been on Keto/OS for 18 days. It taste great. As far as the “benefits” Pruvit insist come from taking it, I have not experienced a single one. In fact during the first week I actually gained 2 lbs and just in the last couple of days have lost them, putting me where I was before taking the supplement. I have not experienced any energy increase or brain clarity. I’m still having migraines and chronic pain. My hair and skin have not changed. I haven’t gained any strength. I still wake several times during the night. The only thing that has happened is that I am in ketosis. Since I am on the KETO diet (pre-Pruvit) I was already in trace ketosis, but 1 hour after drinking the supplement it does go up to moderate, by bedtime though its back to trace. Since I paid for a 30 day supply I’m going to go ahead and finish it even though I’m not getting any benefit out of it. My former fitness instructor/nutritionist (I moved) has been using it personally and on her clients and reports nothing but great things from her clients. They all seem to be losing weight and gaining energy and strength every day. I’ve been looking for complaints or testimonials from people who the product isn’t working, but I must be the only one. I’m glad it works for people, I just wished it was working for me.

    • Your ketone levels are likely higher when you drink it becuase you’re drinking more exogenous ketones, not because your body is mobilizing more fat into ketones (which is the assumption I think you’re making from the results of the test strips). The only way to lose more weight is to increase metabolism through training, sleep, exercise, health issues could be preventing acceleration, we are complicated multivariable systems, this is not a miracle drink. I would suspect that the people that it is working for are performing more work, using the ketones to fuel the increased volume of training.

    • ask your trainer if she is with the company and actively selling it. MLM will say whatever they need to make the sell. Trust me, I know!

  27. I Took the packet right before bed so I’d be in ketosis through the night. It worked so I’m impressed.
    I started the ketogenic diet 3 months ago. Corrected my diet to be 5% carbs, 15% protein, 80% fat, lost 20 lbs in 3.5 weeks. Found my sweet spot, perfect balance of food and exercise to stay burning. I worked hard at it and became keto adapted. Btw, it can play weird games with your body during the adaptation process. I felt strange pains in my arms and shoulders, localized type pains. That subsided after 1 month and everything has been great since. I only mention it because ketosis is something you really should adapt to with diet, first. Learn how to get there (and stay there) with your diet. And use KETO OS as a supplement on days you had a bad meal. I see the beauty of Keto os, because a major battle with the ketogenic diet is keeping focused. Avoiding the bad meal that throws you out of ketosis and you spend the next week diligently working to get back in. This product will help me stay in burning mode while I try to find my “sweet spot” again.

  28. Will your product register ketones on a blood ketone monitor? It’s my understanding that urine ketone strips just test for a by-product of ketones that are produced.

    • that is precisely true. it will trick a ketosis test if you are not in ketosis because it puts the ketones in your bloodstream without putting your body into ketosis. If you are already in ketosis, it will not take you out of ketosis but still put ketones (fuel that your body, if in ketosis, would create from fat). this would be counter-productive for weight loss.

  30. From the FAQ’s:


    Through use of a double-negative, part of the FAQ answer is unsettling:

    “…..There is no reason that the ketones produced by the product will affect the kidneys or liver any differently than ketones produced from exogenous fats (such as when eating a ketogenic diet) or ketones produced from stored fats (such as when calorie restricting or losing weight). Exogenous ketone scientific literature does not suggest that neither the kidney nor liver function is negatively affected by ketosis….”

    One would be wise to read reliable outside sources of information available on the subject.

  31. I’ve been taking this now for 3 weeks. I have been experiencing a hang over feeling for the past 2 days and I don’t like how I feel. I don’t have and gi problems but I am very constipated. I am diabetic type2. Unfortunately I didn’t consult a doctor and I now fear I am damaging my body. I also didn’t pay attention to the “high salt content” and I have high blood pressure which has been unusually higher than normal. I am alarmed and I do plan on contacting my doctor tomorrow. I do hope it’s not anything serious because I am enjoying the energy and weight loss.

  32. WOW !!! An hr ago I tested my urine and had slight ketosis 5. Just tested again, and it was small ketosis 15!!! I try to stay below 20 carbs a day. At first I didn’t think that vegetables like avocadoes, tomatoes and broccoli would make a bgi difference, but when you’re trying to fill up on veggies it is EASY to go over 20 carbs…

    • its garunteed that your blood will have more ketones, you just drank ketone bodies, the downside is that your body won’t be in any more of a state of ketosis or mobilizing any more fat solely becuase of drinking the supplement.

  33. I have been on this for 5 days. I have not lost any weight. I am having GI episodes and discomfort too. I understand I have to get used to it but am wondering about the weight loss.

    • Dianne,

      Thanks for leaving a comment. I know Pruvit recommends starting with a 1/2 or even 1/4 dose at first if you begin to have symptoms. You may want to try that. Also make sure you are staying hydrated.

      Hopefully that helps.

    • product does contain dairy ingredients so you may be having a reaction or intolerance to the product. This is not a weightloss product (as it says on the package) so you may want to re-think your strategy if that is your goal.

  34. KETO-OS for 14 days. I’m feeling wonderful with even and increased energy all day long! Daughter is no longer having teen mood swings and husband’s back pain is disappearing day by day! Oh yes.. enjoying weight loss – no more love handles! Financial bonuses are stellar, too!

  35. The only patent product that has gone thru trials and is science backed out of University of South Florida Dr. Dominic D’agostino doing a Navy Seal Study Ketopia

    • Natalie,

      Thank you for commenting. I want to show you what is found on the Pruvit KETO-OS FAQ page. It was also mentioned in the article above.

      “Keto-OS is your “Ketone Operating System” it is the First Therapeutic Ketone Supplement on the market. The proprietary blend is owned by Prüvit and is Dr.Approved, Lab Tested, University backed and the technology in Keto-OS is patent pending, developed by one of the most world renown Dr.’s and experts on Ketosis. Prüvit was the first company approved by University of South Florida to acquire the sublicense rights to use this patent pending technology. It is a powder that you mix with 8=10 oz. of water. Within 15-30 minutes it puts your body into Ketosis. Prüvit owns the worldwide rights to Keto-OS. Keto-OS has a certificate of analysis for purity, consistence and efficacy.”

      The science for BOTH came out of the University of South Florida.

        • Rob,

          No, not necessarily. It’s just that Pruvit and ForeverGreen both can’t claim that they are the sole holders of the science behind these products. Did you take a look at the lawsuit that is currently taking place between the 3 companies?

          — Supplement Police

    • Stacey,

      I do believe they do. Let me send you some information. Be on the lookout for the email “(I am BETTER)” that I’ll message over to you. Should have the information you need.

      — Supplement Police

      • I Am BETTER is one of the shirts in my clothing line (which features the “I Am…” statement on the front and an acronym on the rear). I Am… BETTER is


        That speaks to the mindset I believe one must possess when going to the gym. Just thought I’d share that.


    • Nikki,

      According to their FAQ, here is the reasoning:

      “Keto-OS was formulated with a higher salt concentration in order to counter balance the sodium that is lost through ketone supplementation. It also acts as a slight buffer, since ketones can be a bit acidic. When taking exogenous ketones, it is often encouraged that you increase your salt intake, with Keto-OS, the additional sodium is provided for you.”

      So there is a reasoning behind the amount of Sodium. And I believe in Keto-OS 2.0 they actually changed the source of sodium.

      “We have evolved to a two salt combo of Sodium & Calcium. This cut our sodium content down by 50%. This is great news for those that are hyper sensitive to sodium/salt.”

      That Nutrition Facts image was from their current website, so I would assume it is the up to date version 2.0. They are also working on version 3.0 with a 4 salt combo, but no timeline on when that would be released. It seems they are committed to making sure the product can work for a wide range of customers.
