Extreme Endurance is a revolutionary athletic performance formula created by athletes for athletes. This formula 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 claims on individual ingredients but Extreme Endurance has a published study on the formula itself.
Each batch of Extreme Endurance is tested to ensure that it is not contaminated with banned substances to provide additional reassurance for elite athletes.


As an athlete, I have searched for ways to improve my health and athletic performance. Extreme Endurance has the clinical studies and naturally ingredients that peaked my curiosity and warranted further investigation in my own research. Occasionally, do I get impressed with companies and rarely do I get to the converse with the CEO as I did with the Owner of Extreme Endurance, Sandy Kellin. He gave me the knowledge and power to truly see the validity, safety and passion that are in his products. I was able to understand his family’s vision and dedication to make the most effective and healthy endurance product on the market.   Extreme Endurance buffers the hydrogen ions (H+) acid that is exercise induced lactic acid. A more neural pH is essential for proper health and optimal athletic performance. It does this safely and naturally with primary and secondary ingredients. The secondary ingredients are comprised of Papain, Catechins and electrolytes that reduce tissue damage, inflammation, oxidative stress, suppressed immune function and restore basic electrolytes balance. They also had a third party, double blind placebo controlled, cross over study performed to show the effectiveness and was published in a Clinical Journal for the results. The study revealed a 15% reduction in lactic acid and an increase in aerobic threshold by double digits. I personally noticed that the muscle burn was delayed with intense cycling intervals and the delayed “next day” soreness was much less with recommended daily consumption. Extreme Endurance is certified and continually tested for any and all banned substances so you can rest assured on the safety of the ingredients.
