Abstract

The Norwegian Scientific Committee for Food Safety (VKM) has, at the request of the Norwegian Food Safety Authority, assessed the risk of specified doses of L-leucine, L-isoleucine and L-valine in food supplements. VKM concludes that: Due to lack studies addressing adverse effects of the specified doses 2500, 3000, 4000, 5000 and 5250 mg/day L-leucine, 1500, 1750, 2000 and 2500 mg/day L-isoleucine and 1500, 1750, 2000, 2250 and 2500 mg/day L-valine in food supplements, no conclusions can be made for adults (≥ 18 years), adolescents (≥ 10 and < 18 years) or children (< 10 years).
