Foods high in niacin (vitamin B3)

Niacin (vitamin B3) helps the body release energy from food and supports the normal function of the skin and nervous system. Dried mushrooms, wheat-based and rice-based baby cereals, and fortified malted flake breakfast cereal are among the foods leading this list. Tuna and lamb’s liver also appear among the leading foods, in the raw or cooked forms specified.

The list ranks foods by their niacin content per 100g, rather than by the amount usually eaten. Typical portion sizes therefore matter when comparing foods. Drying removes water, which can concentrate nutrients by weight, while fortification adds vitamins to some cereals. Salt, sugar and saturated fat content may also be relevant when comparing these foods. Full nutrient figures are provided in the tables below.
