Amazing product

You don’t realise you need this until you start using it… able to run every single day now at age 40 without the persistent issues with muscle soreness that limited me to 4 runs per week.

I love running and the 100km to 120km per week shows me how effective these tablets are.

The positive effects last longer than stated too, forgot them on holiday but felt no issues getting back to it.

Have you ever had a burning sensation in your muscles during intense exercise? This is a signal that your body is being deprived of oxygen - and lactic acid is being created. When your body produces lactic acid, it splits into two ions; lactate ions (lactate) and hydrogen ions (H+) . H+ is the acid in lactic acid. Intramuscular Acidosis – The pH (acid) is not due to lactate but rather the production of H+ which is part of the process of energy released from the breakdown of glucose. As H+ are released, intramuscular pH goes acid leading to fatigue and creates the burning feeling in your muscles during intense exercise.


What exactly is this elusive VO2 Max, why is it important to know, how is it measured, and how can you improve your VO2 Max? VO2 Max is the maximum amount of oxygen you can consume that goes to the working muscles. In short, we need oxygen to survive and perform daily living activities, not just during exercise. If we want to use oxygen more efficiently by increasing VO2 Max, activities such as nutrition, movement, and breathing all need to be taken into consideration for improvement. We all want to breath better and stronger!


The same process that causes a car to rust, plays a similar corrosive role in our bodies. It is called oxidation. Oxidative stress is essentially an imbalance between free radical production vs antioxidants. Antioxidants constantly fight to neutralize free radicals, thereby improving cell function. Oxidative stress can damage cells and contribute to the aging process. Oxidative stress may also play a role in several diseases such as cancer, Alzheimers, and diabetes. The goal should be to flood your body with powerful antioxidants and ward off the effects of free radical damage in the body.


Health is a daily consideration. Or should be! Whether you are looking for performance, anti-aging or recovery, Xendurance should be taken daily. This proprietary combination of ingredients should be consistently released into your system twice a day for ongoing support. It starts working 48-72 hours after you take it and the science shows the longer you take Xendurance, the greater the benefits. Take it daily!

Over the years we have found that some people have a very acidic diet and their diet may interfere with the dissolution of the product in the small intestine. On the other hand, one of our athletes drinks 12 cups of coffee per day and lives on Xendurance with great results! Everyone is different but the few that have had issues cleared up the dissolution problem by limiting acidic drinks, red meat and coffee when taking Extreme Endurance. We now encourage people to take their caffeine within an hour prior or after taking their tablets just as a precaution.

You don’t cycle with Xendurance Lactic Acid Buffer. You take it consistently, like a multivitamin; for training, performance and for better body pH and alkalinity. 3

Xendurance will be in your system and working within 48-72 hours. We can confirm this from 12+ years of clinical testing.

Xendurance can be taken together with almost every other supplement but many times we tell people they should not combine with any more magnesium or calcium. If you are taking any other product with magnesium or calcium, please contact info@xendurance if you are concerned about the amount you are taking.

You do not need to take Xendurance Lactic Acid Buffer with food - we recommend taking them with a big glass of water.
