Under section 201(ff)(1) of the FD&C Act [21 U.S.C. § 321(ff)(1)], a dietary ingredient is a vitamin; a mineral; an herb or other botanical; an amino acid; a dietary substance for use by man to supplement the diet by increasing the total dietary intake; or a concentrate, metabolite, constituent, extract, or combination of any dietary ingredient from the preceding categories. Hordenine HCl does not qualify as a dietary ingredient under section 201(ff)(1) of the FD&C Act because it is not a vitamin; a mineral; an amino acid; an herb or other botanical; a dietary substance for use by man to supplement the diet by increasing the total dietary intake; or a concentrate, metabolite, constituent, extract, or combination of any dietary ingredient from the preceding categories.\u003C\u002Fp>\n\n\u003Cp>If a substance is not generally recognized as safe (GRAS) by qualified experts for its intended use in food and does not qualify for any of the other exemptions from the food additive definition, it is a food additive. Food additives require premarket approval based on data demonstrating safety. Any food additive that has not been approved for its intended use in food is deemed to be unsafe and causes the food to be adulterated under section 402(a)(2)(C)(i) of the FD&C Act [21 U.S.C. § 342(a)(2)(C)(i)].

However, non-dietary ingredients intended for use in dietary supplements, such as the hordenine HCl used in your product, are not exempt from the food additive definition and must meet the same requirements as substances added to conventional foods. In other words, a non-dietary ingredient added to a dietary supplement must be used in accordance with a food additive regulation or be GRAS for its intended use, unless it qualifies for another exception to the food additive definition.\u003C\u002Fp>\n\n\u003Cp>Hordenine HCl is not generally recognized as safe under its conditions of use in your dietary supplement product.
