Niacin (vitamin B3 as nicotinic acid) assists the body in metabolising carbohydrates, proteins and fats. It also contributes to normal psychological function and prevents a niacin deficiency, as well as contributing to the reduction of tiredness and fatigue.
Each tablet contains the following active ingredient:
|Niacin (Vitamin B3)||35mg|
Inactive ingredients: Microcrystalline cellulose, sodium starch glycolate, magnesium stearate and silicon dioxide.
Suitable for vegans and vegetarians.
Niacin is a precursor of nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), which is essential for oxidation-reduction reactions, ATP synthesis, and ADP-ribose transfer reactions.
Take 1 tablet daily, after food.
Niacin often causes red flushing of the skin, especially when consumed on an empty stomach. It is therefore recommended to start by taking a quarter to half tablet daily after food, gradually increasing the daily dose to 1 tablet.
Side effects include flushing, tingling and itching sensations as well as redness on the face, arms and chest. They are usually transient and disappear with continuous use. Other side effects are rare, but include nausea, bloating, flatulence, hunger pains, vomiting, heartburn, diarrhoea, increased sebaceous gland activity, low blood pressure, dizziness, rapid heart rate, irregular heartbeat, and blurred vision. Very high doses (greater than 3000 mg daily) might cause jaundice and elevated serum transaminases. Such high doses should be discontinued if liver function tests rise to three times the upper limit of normal.
