Essential micronutrients are vitamins and minerals required by the body in small amounts to maintain normal physiological functions, growth, and overall health. They play crucial roles in enzymatic reactions, hormone production, immune function, and maintaining structural integrity of cells and tissues. Micronutrients can be broadly classified into vitamins, which are organic compounds, and minerals, which are inorganic elements. Vitamins are further categorized into fat-soluble (A, D, E, and K) and water-soluble (B-complex and C). Vitamin A is essential for vision, epithelial tissue maintenance, and immune function. Vitamin D regulates calcium and phosphorus metabolism, contributing to bone health. Vitamin E acts as an antioxidant, protecting cell membranes from oxidative damage, while Vitamin K is crucial for blood clotting and bone metabolism.
