Xendurance is a sports nutrition company that was started in the USA in 2006 when the formula, Xendurance (Extreme Endurance in the USA) was under development and is best known as the sponsor for athletes like Josh Bridges and other re-known Cross-training athletes.

What distinguishes Xendurance from other sports nutrition companies is that the Xendurance showcase their product and has a published, Gold-Standard, third party, double-blind, placebo-controlled, crossover study backing up claims of 15% reduction in lactic acid and a double-digit increase in aerobic threshold. Many companies make substantial claims on individual ingredients, but Xendurance has a published study on the complete formula, not just the ingredients.“Third-party” testing is also important because it means that Lifespan International did not know or hire the actual facility that did the testing, therefore, no bias was influencing the outcome of the study.

Xendurance continues to be at the forefront of using this science and success in providing sports nutrition to athletes in every sport, no matter the level of participation or performance.
