7 Foods High in Niacin (Vitamin B3)

Vitamin B3 or niacin is one of eight essential B vitamins that are necessary for nerve functioning, energy production, cellular formation, and much more (1). Vitamin B3 is a part of the B vitamin complex.

How can you tell if you are low or deficient in vitamin B3? Common vitamin B3 deficiency symptoms rough skin that turns red in the sun, headaches, a bright red tongue, vomiting, memory loss, and more (2). Severe vitamin B3 deficiency is a disease called pellagra (3). Although vitamin B3 deficiency is not very common in North America, it does rarely occur (4).

Niacin is one of the water-soluble B vitamins, so excess niacin is easily excreated in the urine (5). However, too much niacin can lead to common symptoms like a red flush. This is known as the niacin flush (6), (7).
