The FDA regulations for supplement labels require that vitamins listed in the upper portion of the label only include amounts for the isolated “organic nutrient” portion of the specific vitamin with its RDA (ascorbic acid for vitamin C or alpha-tocopherol for vitamin E). The concept of milligrams and units of vitamins simply has no meaning when applied to whole foods.
