Vitamins and Minerals
Definition
Vitamins are organic micronutrients required in small amounts, while minerals are inorganic elements or ions needed for normal body structure and function.
Formula / Key Relation
Examples of functions:
Vitamin A → vision and normal tissue function.
Vitamin C → important in connective tissue and normal healing processes.
Vitamin D → supports calcium absorption and bone health.
Calcium → bones and teeth.
Iron → haemoglobin.
Iodine → thyroid hormone production.
Vitamins:
organic micronutrients.
Minerals:
inorganic micronutrients.
Examples:
`Ca`, `Fe`, `I`
Vitamins and Minerals — Advanced
Micronutrients are required in relatively small quantities compared with macronutrients, but deficiency can still disrupt important biochemical pathways.
Vitamins participate in many regulatory and metabolic roles, while minerals may act as structural components, ions or cofactors.

Vitamins and minerals are essential micronutrients required in small amounts for many normal biological functions.
Vitamins and minerals are micronutrients, meaning the body needs them in relatively small amounts. Vitamins are organic compounds, while minerals are inorganic elements or ions. Vitamin A supports vision, vitamin C contributes to normal connective tissue and healing, and vitamin D supports calcium use and bone health. Important minerals include calcium for bones, iron for haemoglobin and iodine for thyroid hormone production.
