                                According to the National Institutes of Health, humans cannot produce their own vitamin C and must obtain it from diet or supplements. This essential nutrient, also known as ascorbic acid, is a water-soluble vitamin that plays a vital role in immune function, collagen synthesis, and antioxidant protection.
