Xendurance Extreme Endurance

When the Xendurance nutrition company was founded in 2006, their central goal was the development of a recovery formula that would safely and effectively target lactic acid—one of the biggest factors in muscle fatigue and soreness. The result was Extreme Endurance, a scientifically tested supplement that can reduce the output of lactic acid by as much as 15%, enabling athletes to compete longer, extend their aerobic thresholds, and recover faster.

The ingredients in Xendurance Extreme Endurance (including Calcium Carbonate, Catechins, and the enzyme Papain) all meet the strict permissible guidelines of leading sports organizations like the IOC, NCAA, NFL, NBA, and MLB. The formula comes in a non-chewable tablet form, with a recommended dose of six tablets each day (3 in the morning, 3 in the evening) all year long for the best results.


  • Clinically tested recovery formula
  • Designed to reduce Lactic Acid and muscle soreness, increase endurance, and recovery speed
  • Certified Drug-Free
  • Benefits should begin within 3 days of starting daily use
  • 180 Tablets per package
  • Daily dose: 6 tablets per day (non-chew, with or without food)

Rated 5 out of 5 by from Take religiously like my multi-v's I came back to Extreme Endurance after previously not noticing anything special. I'm on my 3rd bag I think and I have to say it's been amazing. I do a high capacity program (not crossfit) 6 days a week and I have had no lactic acid issues that use to plague me anything I got physical. I've recently started expanding into more XEndurance products and have been impressed

Rated 5 out of 5 by from Real Deal Hey guys I am only writing this to add to the rating - I cannot stand astroturfed reviews on retail sites so let me state up front - this is 100% from my true experience. I am a bike racer. I ride lite level over 20 race weekends a year, race in CZ and Belgium too. I am talking 15k miles a year at very hard effort. This supplement is one of very few that I have tried over 25 years as a sponsored amateur and pro athlete since my teens, that actually works. To prove I am not a shill - there is another one, Sportlegs. Trust me, if you deal with lactic acid burn, in endurance sport, even MMA or Crossfit long events, try this stuff. .

Rated 5 out of 5 by from This actually works I bought this a few months ago prior to building up to a local competition. If you take this as prescribed you can kiss the burn good bye. You can train so much harder and it doesn't break the bank. Love this stuff.

Rated 5 out of 5 by from It works This product works very well. I took a challenge from a friend to run a half marathon without traditional marathon training, just crossfit workout. I started taking this two weeks before the training. I finished my marathon in 2:04 and went for a bike ride in the afternoon after the run. Recovery was a piece of cake.
