Assessment of dietary intake of nicotinic acid and nicotinamide in relation to tolerable upper intake levels. Opinion of the Panel on Nutrition, Dietetic Products, Novel Food and Allergy of the Norwegian Scientific Committee for Food Safety. VKM report 2017:27

Abstract

The Norwegian Scientific Committee for Food Safety (Vitenskapskomiteen for mattrygghet, VKM) has,at the request of the Norwegian Food Safety Authority (Mattilsynet; NFSA), assessed the intake of niacin in the Norwegian population. NFSA has also requested that VKM conduct scenario calculations to illustrate the consequences of establishing separate maximum limits for nicotinic acid(1, 4, 8 or 10 mg/day)and nicotinamide (100, 500, 700 or 900mg/day)in food supplements, by assessing these scenarios against existing tolerable upper intake levels (ULs).The current maximum limit for niacin added to food supplements is 32mg/day, including nicotinic acid, nicotinamide and inositol hexanicotinate.
