Vitamins

Organic micronutrients required in small amounts for normal metabolic function.

Water-soluble

B-vitamins and vitamin C are not stored in large amounts and should feature regularly in the diet.

Fat-soluble

Vitamins A, D, E, and K are absorbed with dietary fat and stored in body tissues. Excess intake from supplements can accumulate.

Deficiency and excess

Both extremes cause problems. Diverse whole-food diets cover most requirements; supplementation is best guided by clinical assessment.
