Xendurance – Extreme Endurance Workout Performance Products?


The performance supplement industry offers athletes, fitness enthusiasts, and sports players a wide range of dietary additives, micronutrients, and compounds that are able to dramatically improve their overall performance and physical ability.

Unlike the health supplement industry, which is focused on improving the overall health of the body, the performance supplement industry is aimed at helping athletes take their bodies to the natural limit.

Performance supplements are able to increase the rate at which the body is able to build new lean muscle mass, promote a higher metabolic rate, enhance the speed at which the body can convert fat tissue into energy, boost endurance, increase strength output, and significantly lower recovery time.

In a world where a fraction of a second can mean the difference between a gold or bronze medal, optimizing nutritional intake to maximize the output of the body is critical.

The highly regulated nature of competitive sports, however, can make choosing the right performance supplement extremely difficult.

There are extremely strict rules regarding the supplements and substances used by professional athletes to gain a competitive edge, with various governing boards blacklisting a broad spectrum of supplements that have been demonstrated to deliver an unfair advantage.

Determining whether a performance supplement or dietary aid is both effective and legal can require a significant amount of time consuming research, and, even then, there’s no guarantee that it won’t cause a biological reaction that can create a false positive in doping tests.

These issues are further compounded by the fact that many supplement companies don’t provide a full list of their active ingredients, or hide them behind “proprietary compounds”.

A new sports supplement company, however, has made it possible to gain powerful, highly effective, and completely legal performance-boosting dietary supplements from a centralized, certified, and safe source.

Xendurance are the leading professional sports and athletics performance supplement brand on the market, and offer a diverse range of supplements and products that can help athletes, sports players, and even everyday fitness enthusiasts reach their goals faster and push their bodies further,

In this article, we’ll take a look at the Xendurance brand, find out what makes them different from other performance supplement providers, and examine their product range to help you decide whether they’re the right supplement brand for you.

What Is Xendurance?

Founded in the United States in 2006, Xendurance is a sports nutrition company that operates as an extension of the Lifespan International US brand.

The Xendurance company was built around a formula that Lifespan International was working on called Extreme Endurance. Extreme Endurance was intended to increase the physical capacity of an athlete through the use of completely natural substances, improving aerobic ability and lactic acid threshold.

The Extreme Endurance formula, when released by Lifespan International, was met with widespread acclaim, and caused the company to create an expanded line of sports and athletics based natural performance supplement.

Xendurance supplements have been subjected to rigorous scientific scrutiny and have been featured in a wide range of best-selling books, supplement news sites, fitness and health magazines, and various newspaper articles.
