New labeling guidelines require reporting of vitamin A in the unit of mcg RAE, (retinol activity equivalent) in order to account for the differing bioavailability of the forms. Vitamin A has previously been reported in international units (IU). Some of these forms have greater bioavailability than others. Vitamin A in the diet can come in different forms: retinol, beta-carotene, alpha-carotene, and beta-cryptoxanthin.

For more information from the FDA, click here.ġ mcg RAE = 2 mcg supplemental beta-caroteneġ IU = 0.67 mg for d-alpha-tocopherol (natural)ġ IU = 0.9 mg for dl-alpha-tocopherol (synthetic)ġ mg vitamin E (as alpha-tocopherol) label claim = 1 mg of natural α-tocopherolġ mg vitamin E (as alpha-tocopherol) label claim = 2 mg of synthetic α-tocopherol The FDA will permit manufacturers to include the amounts of nutrients in the old units in parentheses adjacent to the amounts in the new units. The changes that will affect the application of DSID results are the changes in the units used to declare vitamins and minerals on supplement labels. Voluntary compliance prior to that date is permitted, and it is expected that there will be a period of time when both types of labels will be on the market. The new regulations will be mandatory in 2019-2020. Food and Drug Administration (FDA) announced regulations that require amendments to the existing supplement facts label, which uses units and conversions based on the 1968 Recommended Daily Allowances (RDA).
