1. Liver
Liver is one of the best natural sources of niacin.
A typical 3-ounce (85-gram) serving of cooked beef liver provides 14.7 mg of niacin, or 91% of the RDA for men and more than 100% of the RDA for women.
Chicken liver is also a good source, providing 73% and 83% of the RDA for men and women per 3-ounce (85-gram) cooked serving, respectively.
In addition, liver is incredibly nutritious, packed with protein, iron, choline, vitamin A and other B vitamins.
Summary Liver
is one of the best natural sources of niacin, providing 91% of the RDA for men
and more than 100% of the RDA for women per 3-ounce (85-gram) serving.
2. Chicken Breast
Chicken, especially the breast meat, is a good source of both niacin and lean protein.
3 ounces (85 grams) of cooked, boneless, skinless chicken breast contain 11.4 mg of niacin, which is 71% and 81% of the RDA for men and women, respectively.
In comparison, the same amount of boneless, skinless chicken thighs contain only half that amount.
Chicken breasts are also packed with protein, containing 8.7 grams per cooked ounce (28 grams), making them an excellent choice for low-calorie, high-protein diets designed for weight loss.
Summary Chicken
breast is an excellent source of lean protein and niacin, containing 71% and
81% of the RDA for men and women, respectively. In comparison, chicken thighs
provide roughly half that amount.
