Vitamins are organic compounds that the body needs in small amounts for essential metabolic processes, while minerals are inorganic elements required for structural support and various physiological functions.

The Recommended Dietary Intake (RDI) is the average daily intake level of a nutrient that is sufficient to meet the nutritional requirements of most healthy individuals. RDIs are established by health authorities based on scientific evidence and are used as guidelines for dietary planning and nutrition labeling.

Vitamins are classified into two groups: fat-soluble vitamins (A, D, E, and K) and water-soluble vitamins (B-complex vitamins and vitamin C). Each vitamin has specific roles in supporting various bodily functions, such as vision, bone health, antioxidant protection, and energy metabolism.

Vitamins are found in a variety of foods, including fruits, vegetables, whole grains, lean proteins, dairy products, and fortified foods. Consuming a diverse and balanced diet ensures adequate intake of vitamins.

Minerals are categorized into macro minerals (such as calcium, magnesium, potassium, and sodium) and trace minerals (such as iron, zinc, copper, and selenium). These minerals are essential for bone health, nerve function, fluid balance, and enzyme activity.

Minerals are found in a wide range of foods, including fruits, vegetables, whole grains, nuts, seeds, lean meats, dairy products, and seafood. Some minerals may also be obtained from fortified foods or dietary supplements.
