Bicarbonate de sodium

Sodium bicarbonate is a natural mineral salt with the formula NaHCO₃, found naturally in certain mineral springs and produced industrially via the Solvay process. It has been used for centuries in food, cosmetics, and traditional medicine, particularly for its alkalising properties. Physiologically, sodium bicarbonate contributes to the body's acid-base balance. It acts as a buffer that helps neutralise excess acid in bodily fluids, which may support digestive comfort and muscle recovery after intense physical exercise. Studies suggest it contributes to reducing lactic acid build-up in muscles during high-intensity efforts. Sodium bicarbonate supplementation may be of interest to athletes looking to support their performance during anaerobic efforts, as well as to individuals seeking to maintain an optimal acid-base balance. Intake should be carefully adjusted, as excessive doses may disrupt electrolyte balance.
