Vitamins are essential organic compounds that play crucial roles in various physiological processes, growth, and overall health. They are required in small quantities and often act as coenzymes or cofactors in metabolic reactions. Vitamins can be water-soluble (e.g., vitamin C, B-complex) or fat-soluble (A, D, E, K). Each vitamin has specific functions, such as antioxidant protection, energy metabolism, immune support, and bone health. As the human body cannot synthesize most vitamins, obtaining them through a balanced diet is essential. Vitamin deficiencies can lead to various health disorders, highlighting the significance of vitamins in maintaining optimal well-being.
