NOW Niacinamide is a form of Niacin to helps support skin health, immunity and energy production.

Niacinamide (Vitamin B-3) is a form of niacin, a water soluble B-vitamin. It is a derivative of niacin that does not cause the "flush" normally associated with taking high doses of niacin. Niacinamide is readily converted into the bioactive forms of niacin, NAD+, NADH, NADP, and NADPH, which are vital cofactors in cellular energy production and are critical for the maintenance of DNA stability.

Niacinamide and niacin are two different forms of vitamin B-3. Niacinamide does not cause a niacin flush.

FAQ's for Niacin

  • How come my skin goes red and blotchy?

    This is called Niacin Flush. Niacin flush is a common side effect of taking high doses of niacin (vitamin B3), especially in its immediate-release form.

  • What is a Niacin Flush?

    A niacin flush is a temporary reddening and warming of the skin, usually on the face, neck, chest, and arms. It’s caused by vasodilation—the widening of blood vessels—triggered by niacin.

  • What Causes It?

    When you take niacin, it stimulates the release of prostaglandins, which expand capillaries and increase blood flow near the skin’s surface. This causes:

    • Redness

    • Warmth or heat

    • Itching or tingling

    • Occasionally mild burning

    The effect typically begins 15–30 minutes after taking niacin and can last up to an hour.

  • When Does It Happen?

    More likely with immediate-release niacin (e.g., supplements over 50–100 mg). Less common with slow-release or no-flush forms (like inositol hexanicotinate). The Flush may decrease over time as the body adapts.

  • Is It Harmful?

    No, it’s usually harmless—just uncomfortable. However, very high doses of niacin (above 2000 mg/day) should only be taken under medical supervision due to potential liver toxicity.

  • How to Reduce or Prevent a Niacin Flush?

    • Take niacin with food

    • Start with a low dose and increase gradually

    • Try sustained-release or no-flush formulations

    • Avoid alcohol or hot beverages when taking niacin

    • Some people use aspirin (81–325 mg) 30 minutes beforehand (consult a doctor first)
