Bicarbonates are referred to as "alkaline" salts. This means they have the ability to neutralise or counteract acids. Both potassium and sodium bicarbonate can reduce acid levels in the stomach, increasing the uptake and absorption of various nutrients such as Glutamine and Creatine. As an aid to performance, sodium bicarbonate is used by athletes in sports such as rugby, long-distance running, football and cycling, to combat the fatiguing effects of another acid - lactic acid .During very intense exercise, lactic acid accumulation in the muscle cell can lead to premature fatigue. Sodium bicarbonate promotes the removal of lactic acid from the muscle cells into the blood stream.
