Xendurance Extreme Endurance supplements have been specifically designed to improve your athletic performance and reduce lactic acid by 15%. These supplements will improve your aerobic threshold and reduce muscle fatigue and soreness.

WHY USE XENDURANCE: As an athlete the harder you exercise and compete, the more acid builds up in your muscles, as your blood and muscle pH goes down into the dreaded acid zone the increased use of muscle glycogen, for energy produces lactic and pyruvic acid. Acidity reduces muscle power and reduces physical and mental endurance. You, your colleagues and your coaches refer to this as lactic acid build-up or lactic acid fatigue. Your body's acid concentration increases as you produce lactic acid. Lactic acid is split into Lactate (Lactate ions) and Hydrogen ions. H+ (Hydrogen ions) is the acid in Lactic acid. Lactate is good and is an extremely fast fuel that is preferred by the heart and muscles during exercise. Lactate is vital for ensuring that your body gets a steady supply of carbohydrates. H+ (Hydrogen ions), the other half of Lactic Acid is not good, especially when the acid concentration exceeds the body's ability to no longer neutralize or flush the waste from your body.

DIRECTIONS FOR USE

Five to seven days before a race increase your dosage to 8 tablets a day; 4 in the morning and 4 in the evening and continue this 8 tablet routine for one day after the race and then drop back down to 6 tablets per day. We suggest this as it helps immensely with recovery.
