Fat-soluble vitamins (A, D, E, K) are insoluble in water, stored in liver and adipose tissues, while water-soluble vitamins (B group, C) must be regularly supplied in the diet due to easy excretion except for vitamin B₁₂.

Fat-soluble vitamins (A, D, E, K) are insoluble in water, stored in liver and adipose tissues, while water-soluble vitamins (B group, C) must be regularly supplied in the diet due to easy excretion except for vitamin B₁₂.
Vitamins are classified based on solubility into water-soluble and fat-soluble. Water-soluble vitamins (e.g., vitamin C, B-complex vitamins) dissolve in water, are not stored in the body, and require regular intake. They play roles in energy metabolism and cellular functions. Fat-soluble vitamins (A, D, E, K) dissolve in fats and are stored in body tissues. Their absorption depends on dietary fat. Fat-soluble vitamins contribute to processes like vision, bone health, antioxidant defense, and blood clotting. The classification reflects their transport, storage, and excretion dynamics, influencing recommended dietary patterns for optimal health.
