Glossary Vitamins

organic compounds essential for various metabolic processes in the body

Vitamins are organic compounds that are essential for various metabolic processes in the body. They are required in small amounts and must be obtained through diet because the body either does not produce them at all or produces them in insufficient quantities. Vitamins play crucial roles in maintaining skin health, supporting the immune system, and promoting hair growth, among other functions. For instance, Vitamin D is important for calcium absorption and bone health, while Vitamin B7 (biotin) is often linked to hair and nail strength.
