Nicotinamide

A niacin form used to make NAD and NADP without the typical flushing effect of nicotinic acid.

Nicotinamide is also called niacinamide. It is common in fortified foods and supplements.

What the form means

Nicotinamide supports niacin coenzyme biology and is used in many products. It should be kept distinct from nicotinic acid when reading labels or interpreting supplement studies.

    Nicotinamide is a named chemical form within its parent vitamin family.

Worth knowing

  • Also called niacinamide. Nicotinamide is a common form of vitamin B3 in fortified foods and supplements. It is used to make NAD and NADP, the coenzymes that carry many cellular reactions.

A closer look

Why this form usually does not cause flushing

Nicotinamide does not produce the typical nicotinic-acid flush because it does not bind the same receptors. This difference describes pharmacology at higher exposure; it does not create a separate vitamin B3 requirement or prove that one form is better for ordinary nutrition.
