Vitamins are organic compounds that are essential for the normal growth, development, and maintenance of all body tissues. They play a crucial role in various biochemical reactions within the body and are obtained through the diet or, in some cases, through supplementation. There are two main classes of vitamins: fat-soluble and water-soluble.

Fat-soluble vitamins include vitamins A, D, E, and K. These vitamins are stored in the body's fatty tissues and can be toxic in excess. Vitamin A is important for vision, immune function, and cell growth. Vitamin D is essential for bone health and the absorption of calcium. Vitamin E acts as an antioxidant, protecting cells from damage. Vitamin K is necessary for blood clotting and bone health.

Water-soluble vitamins include the B vitamins and vitamin C. These vitamins are not stored in the body and must be replenished regularly through the diet. The B vitamins include thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9), and cobalamin (B12). Each B vitamin has specific functions, such as energy production, nervous system function, and DNA synthesis. Vitamin C is an antioxidant that supports immune function and collagen production.

Deficiencies in vitamins can lead to various health issues, including anemia, scurvy, beriberi, and rickets. Therefore, it is important to consume a balanced diet that includes a variety of nutrient-rich foods or, when necessary, to consult a healthcare provider about appropriate supplementation.
