What is a Safe Upper Level and for which vitamins and minerals did the EVM set one?
The Safe Upper Level (SUL) represents the maximum amount of a vitamin or mineral that can be consumed daily throughout people’s lives without risk to their health. Recommendations for SULs have only been made where there was enough evidence to support them. The Expert Group on Vitamins and Minerals have recommended SULs for the following: vitamin B6, vitamin E, betacarotene, boron, copper, nickel, selenium, silicon and zinc.
