high strength pure nicotinamide, the non-flushing form,taste-free tablets,great value for money for 100% uk-made,pharmaceutical grade vitamin, made to gmp standardsniacin is the general term for vitamin b3, as it can occur in several forms including nicotinic acid and nicotinamide, the latter of which we think is the best form to use in supplements. niacin is usually obtained from the diet from high protein foods such as meat, fish and nuts.niacin contributes to the normal function of the nervous system, as well as to the maintenance of normal skin and mucous membranes. like many of the b vitamins it is also involved in the metabolic processes that release energy from food.this is a high strength supplement that provides a level of niacin that would be difficult to obtain from your diet alone. we therefore recommend it for relatively short periods of up to 4 months, not because of any safety concerns but because the body is unlikely to need this level for an extended period.high levels of niacin are also included in our b50 complex and b100 complex.
