The U.S. Food and Drug Administration (FDA) has rejected objections filed after publishing its final rule amending “the food additive regulations authorizing the use of vitamin D2 bakers yeast as a source of vitamin D2 and as a leavening agent in yeast-leavened baked products at levels not to exceed 400 International Units (IU) of vitamin D2 per 100 grams (g) in the finished food.” According to the agency, “the objections do not provide any basis for us to reconsider our decision to issue the final rule,” and thus FDA has made no changes to it.
