Assessment of Dietary Intake of Manganese in Relation to Tolerable Upper Intake Level

The Norwegian Scientific Committee for Food and Environment (Vitenskapskomiteen for mat og miljø, VKM) has, at the request of the Norwegian Food Safety Authority (Mattilsynet; NFSA), evaluated the intake of manganese from the diet and 1, 5 or 10 mg manganese per day in food supplements. The former maximum limit for manganese in food supplements was 5 mg per daily dose. 
 Manganese (Mn) is an essential dietary mineral for mammals, and is a component of metalloenzymes such as superoxide dismutase, arginase and pyruvate carboxylase. Manganese is involved in amino acid-, lipid- and carbohydrate metabolism and in proteoglycan synthesis in bone formation. In 2013, the European Food Safety Au…

Assessment of Dietary Intake of Vitamin K and Maximum Limits for Vitamin K in Food Supplements

The Norwegian Scientific Committee for Food and Environment (Vitenskapskomiteen for mat og miljø, VKM) has, at the request of the Norwegian Food Safety Authority (Mattilsynet; NFSA), evaluated the intake of vitamin K in the diet. VKM has also assessed the consequences of establishing maximum limits for vitamin K in food supplements at 100, 200, 300, 600 or 800 µg/day. The former maximum limit for vitamin K of 200 µg/day in food supplements was repealed 30 May 2017.
 Vitamin K is a fat-soluble vitamin required for the carboxylation of glutamic acid residues in proteins that regulate blood coagulation and bone metabolism. The naturally occurring forms of vitamin K present in food and sup…
