Generally accepted with some debate
"Evidence suggests glycerol can enhance hydration and potentially improve exercise performance, but the effects are modest and not universally observed. Studies show benefits in specific contexts like endurance exercise in heat. More research is needed to determine optimal dosing and long-term effects."
Glycerol helps your body retain more water, which can improve hydration, increase muscle fullness, and potentially boost endurance during exercise. It's best used with plenty of water.
