Studies have shown that beverages containing glycerol can enhance and maintain hydration status and may improve endurance exercise performance by attenuating adverse physiological changes associated with dehydration.
Beta-alanine is a non-essential amino acid that has become increasingly popular among athletes and bodybuilders due to its potential to enhance exercise performance. It is a precursor to carnosine, which is an intracellular pH buffer that helps to regulate acid levels in the muscles during exercise. Beta-alanine supplementation has been shown to significantly increase muscle carnosine concentrations, thereby improving buffering capacity and delaying the onset of fatigue.
