Niacin (Vitamin B3) Info

Niacin was the third of the B group vitamins to be discovered, hence its designation as vitamin B3. Historically it has also been called vitamin P. It comes in two different forms: niacinamide (or nicotinamide) and nicotinic acid. Both forms of supplement can provide the body’s nutritional requirements but they have different effects. Niacin influences the cardiovascular system, stimulating circulation and dilating the blood vessels, thus potentially helping to maintain healthy cholesterol levels.

The niacinamide form can initiate a sudden hot tingling flush in some individuals, which is temporary and harmless. It’s caused by the release of histamine, a vasodilator.

People who react with a ‘niacin flush’ may prefer the nicotinic acid form, which is non-flushing.

Niacin (Vitamin B3) Benefits

Niacin deficiency, known as pellagra, used to be called the disease of the 4 D’s: diarrhoea, dermatitis, dementia/depression, and (ultimately) death. Caused by poor dietary nutrition it is now rare in developed countries but still prevalent in countries where malnutrition is common.

Niacin deficiency may present as ulcer formation, dizziness, bad breath, headaches, nausea, irritability and depression.

As part of a vitamin B complex supplementation, niacin supports healthy brain and nervous tissue function and improves the stress response by supporting adrenal function.

As a vasodilator niacin can help ease cramping of the calf muscles and may help treat Raynaud’s disease. It can help regulate hypoglycaemia and may help relieve headaches and migraines.

Niacin (Vitamin B3) Side Effects

Niacinamide forms may cause temporary flushing.

Niacin should always be taken in conjunction with a B complex supplement, as all the B group vitamins need to be present in the correct ratio for optimal effect.

High doses should be avoided in the following conditions: diabetes, low blood pressure, gout, liver disease or ulcers.

Product Reviews

  • Excellent product, great results

    Very happy with this product. Tried another non flushing one & didn't have the same effect. Have also discovered that it is great for treating cold sores - double the dose until the symptoms go away, works a treat (just creates slightly more flushing).



  • Good

    Our skin specialist speaks highly of Insolar and both my husband and I have noticed improvement in our skin. Nelson sun is so hard on the skin and every care possible is needed.
    Healthpost's Insolar is very competitively priced too!
