Vitamins and minerals differ in their roles and characteristics within nutrition. Vitamins are organic compounds required in small amounts for various bodily functions, such as immune support and energy metabolism. They are often categorized into water-soluble (like B vitamins) and fat-soluble (like vitamins A, D, E, and K). In contrast, minerals are inorganic elements that play critical roles in processes like bone health, fluid balance, and enzyme function. They include calcium, iron, and potassium, among others. Both are essential for overall health.
