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.

    it was scary the first time i tried it as developed hot red blotchy rash all over my body and was at work and looked freaky. i didnt realise what had caused it at first, but then did some research to realise it was the Naicin. not sure why this is considered a good thing? very unpleasant

    The claim is truthful. you do not light up like a christmas tree after using this product. I have not bee on it long enough to give an accurate review but was recommended it by my GP to assist with thyroid disease and skin cancers. I will be interested to see how I go.
