Biotin is a water-soluble B vitamin. It serves as an enzymatic cofactor for many of the reactions within the body. Enzymatic cofactors are non-protein molecules that must be present to make enzymes function properly. As an enzymatic cofactor, biotin helps the body with processing food, especially glucose. Proper metabolism of glucose provides the body with energy. Biotin’s effect on glucose can also be beneficial to diabetics as it improves insulin resistance.

Another everyday use of biotin is for its possible effect on hair, skin, and nails. Deficiencies of biotin are linked to skin rashes and hair loss and can be treated with additional supplementation. Biotin is often taken regularly as a beauty supplement to improve nails, hair, and skin structure.

Biotin is an essential B vitamin that ensures some reactions occur properly, assists in the breakdown of foods, helps transport nutrients throughout the body, and is a natural beauty supplement.
