Best Vitamin B3 (Niacin)-Rich Foods for Backyard Birdss

Ranked by vitamin b3 (niacin) content among foods safe for backyard birdss in the Creature Feast catalog.

Peanuts per 100g: 12mg niacin Peanuts contain about 12mg of niacin per 100g, the highest concentration among common feeder foods. Niacin (B3) is a cofactor in NAD and NADP, coenzymes involved in over 400 enzymatic reactions including energy metabolism, DNA repair, and cell signaling. For birds with metabolic rates 5-10 times higher than similarly sized mammals, niacin demand is proportionally extreme.

Sunflower Seeds per 100g: 8.3mg niacin Sunflower seeds provide roughly 8.3mg of niacin per 100g. The niacin in sunflower seeds supports the citric acid cycle, which is the central energy-producing pathway in avian mitochondria. During sustained flight, the citric acid cycle runs at maximum capacity, and niacin-dependent enzymes are the rate-limiting step in this process.

Peas per 100g: 2.1mg niacin Peas provide about 2.1mg of niacin per 100g and also contain tryptophan, which birds can partially convert to niacin. This dual contribution makes peas a useful niacin source for garden birds, particularly ground-feeding species that consume thawed peas from platform feeders during the breeding season when metabolic demands peak.

Pumpkin seeds per 100g: 4.9mg niacin Pumpkin seeds contain about 4.9mg of niacin per 100g, offering a solid B3 contribution from the seed category. The niacin supports skin and feather follicle health, and its role in DNA repair enzymes is particularly important during molt when millions of new feather cells are being produced at a rapid rate.
