Uses & Effectiveness
A disease cause by niacin deficiency (pellagra). Niacinamide is approved by the U.S. Food and Drug Administration (FDA) for these uses. Niacinamide is sometimes preferred over niacin because it does not cause “flushing,” (redness, itching and tingling), a side effect of niacin treatment.
Overview Information
There are two forms of vitamin B3. One form is niacin, the other is niacinamide. Niacinamide is found in many foods including yeast, meat, fish, milk, eggs, green vegetables, beans, and cereal grains. Niacinamide is also found in many vitamin B complex supplements with other B vitamins. Niacinamide can also be formed in the body from dietary niacin.
Side Effects & Safety
Niacinamide is LIKELY SAFE for most adults. Unlike niacin, niacinamide does not cause flushing. However, niacinamide might cause minor side effects such as stomach upset, gas, dizziness, rash, itching, and other problems.
When doses of over 3 grams per day of niacinamide are taken, more serious side effects can happen. These include liver problems or high blood sugar.
