This essential B-vitamin is known for supporting the health of your hair, skin, and nails but it does so much more. Biotin supports protein, carbohydrate, and fat metabolism, turning these nutrients into energy. It"s important to note that biotin is a water soluble vitamin and thus is not stored in the body, it must be replenished every day. Biotin is involved in the formation of glycogen, which your body then uses for energy whether you"re resting or active. These statements have not been evaluated by the food and drug administration.
