At the request of the European Commission, the European Food Safety Authority (EFSA) has launched a public consultation on draft guidance issued by the agency’s panel on Dietetic Products, Nutrition and Allergies (NDA) for niacin, the generic term for the soluble organic compounds nicotinic acid and nicotinamide that belong to the group of B vitamins. Concluding that no new scientific data have become available to change the Population Reference Intake (PRI) for niacin set in 1993, the panel endorses a PRI of 1.6 mg per day for adults and children. The agency will accept comments on the guidance until March 28, 2014.
