Niacinamide, also called nicotinamide, is a water-soluble vitamin that is part of the vitamin B complex. Although it is similar in function to niacin, the two forms of vitamin B3 have different chemical compositions. These differences allow each form of B3 to carry out specific functions in the body.

Unlike niacin, niacinamide does not cause flushing, the reddening, itching and tingling of the skin that some people experience after taking niacin. Niacinamide does not have the same vasodilation properties as niacin

Niacinamide can be synthesized by the body. When niacin is taken in greater amounts than needed for normal body functions, the excess can be converted to niacinamide.

Niacinamide can be used to combat niacin deficiency, which can cause pellagra, a condition characterized by dermatitis, diarrhea, depression and dementia. Both niacin and niacinamide help the body to metabolize fats, proteins, and carbohydrates for energy production.*

Niacinamide has also been found to be beneficial in treating inflammatory skin conditions such as bullos pemphigoid and granuloma annulare.*

Niacin may help to stimulate the insulin-producing cells in the pancreas.*

Frequently Asked Questions
Q: What is the capsule size?
A: Capsule size 0.

Q: What type of capsule does this product come in?
A: This comes in a gelatin capsule. The gelatin is derived from bovine hide (beef skin).

Q: What is the difference between niacinamide and niacin?
A: The difference between niacinamide and niacin lies in the chemical composition of each form of vitamin B3. While niacin contains an organic acid group, niacinamide contains an amino group. This difference in composition allows each form of B3 to carry out specific tasks in the body. For some purposes, however, the two forms can be used interchangeably. The body can convert niacin into niacinamide with help from the amino acid tryptophan.

Q: Does niacinamide cause flushing?
A: No, niacinamide does not cause the characteristic skin flush like niacin.
