Among the 569 types of specific health food and supplements approved by the Ministry of Health and Welfare of Japan, more than 42% contain Oligo. In 1994, Isomalto-oligosaccharide was included by the Ministry of Health and Welfare of Japan as a “Specific Healthy Food”.

FDA-icon In 1990, the American Food and Drug Administration (FDA) classified oligosaccharide as a GRAS food item.

Generally recognized as safe (GRAS) is an American Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements.
