Vitamins are essential organic compounds that our bodies need in small amounts to function properly. They are crucial for a wide range of physiological processes, including growth, metabolism, and immunity. Because our bodies cannot produce most vitamins on their own, we must obtain them through our diet or supplements.

Vitamins are broadly classified into two categories: fat-soluble and water-soluble. Fat-soluble vitamins, which include vitamins A, D, E, and K, are absorbed along with fats in the diet and can be stored in the body's fatty tissues and liver. Water-soluble vitamins, such as the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, B6, B12, and folate) and vitamin C, are not stored in large amounts and are excreted in urine, meaning they need to be replenished more regularly.

Each vitamin plays unique roles. Vitamin A is vital for vision and cell growth. Vitamin D is essential for calcium absorption and bone health. Vitamin E acts as an antioxidant, protecting cells from damage. Vitamin K is critical for blood clotting. The B vitamins are involved in energy metabolism, nerve function, and red blood cell formation. Vitamin C supports the immune system and aids in collagen production. Deficiencies in specific vitamins can lead to various health problems, while excessive intake of some vitamins can also be detrimental. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins is the best way to ensure adequate vitamin intake.
