, high strength pure nicotinamide, one-a-day taste-free tablets, great value for your money for 100% uk-made, pharmaceutical grade vitamin made to gmp standardsniacin is the general term for vitamin b 3 as it can occur in several forms including nicotinic acid niacinamide & 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 & nuts.niacin contributes to the normal function of the nervous system as well as to the maintenance of normal skin & 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 b 50 complex & b 100 complex.
