Because the FDA generally classifies the products it regulates based on intended use and ingredients found therein, among other considerations, an initial stage in determining how a product will be regulated is by looking to the intended use. The FDA generally determines the intended use of a product based on statements, called “claims,” made about a product, i.e., what the marketer claims the product can do. Structure function claims are some of the key statements made about nutritional supplements and vitamins.

Structure Function Claims for Nutritional Supplements and Vitamins

While there are different types of claims, i.e., health claims, disease claims, structure function claims, some claims may cause a product to be subject to heightened regulation. For example, if a product is otherwise classified as a food but its labeling contains disease claims, the FDA will classify this product as a drug. On the other hand, certain claims, called “structure function claims”, may be made about dietary supplement products and, if done correctly, will not cause these products to be subject to heightened regulation. More information about Structure Function Claims and FDA regulations may be accessed here. Thus, when marketing a FDA-regulated product, it is critical to understand what types of claims may be used for your particular product and to ensure that these claims are properly worded and fit within the meaning of structure function claims.
