Reference Notes

"a Food and Nutrition Board, Institute of Medicine (U.S.). Dietary Reference Intakes Tables. b (RDA) = Recommended Dietary Allowance, AI = Adequate Intake, indicated with * c UL = Tolerable Upper Intake Level (from food & supplements combined) d SUL = Safe Upper Levels; SULs and Guidance Levels (indicated by **) set by the Expert Group on Vitamins and Minerals of the Food Standards Agency, United Kingdom. These are intended to be levels of daily intake of nutrients in dietary supplements that potentially susceptible individuals could take daily on a life-long basis without medical supervision in reasonable safety. When the evidence base was considered inadequate to set a SUL, Guidance Levels were set based on limited data. SULs and Guidance Levels tend to be conservative and it is possible that, for some vitamins and minerals, greater amounts could be consumed for short periods without risk to health. The values presented are for a 60 kg (132 lb) adult. Consult the full publication for values expressed per kg body weight. This FSA publication, Safe Upper Levels for Vitamins and Minerals, is available at: http:/ /www.foodstandards.gov.uk/multimedia/pdfs/vitmin2003.pdf e The UL for magnesium represents intake specifically from pharmacological agents and/or dietary supplements in addition to dietary intake.
