How to achieve compliance in the USA?

Dietary supplement labels


The regulations

The label of your dietary supplement is the first introduction of your product and is exposed to both consumers and authorities.

Labeling of dietary supplements must comply with regulations outlined in the Code of Federal Regulations (CFR) under 21CFR §101.36, and 21CFR §101.9 in some instances. These regulations include specific requirements for formatting, nutrition labeling, ingredient declarations, order of ingredients, placement, and font sizes for mandatory information. In addition to regulations in 21CFR §101, product labels must also comply with requirements set by the Federal Trade Commission (FTC), California’s Proposition 65 regulations, and other requirements under certain circumstances.

Ensuring all mandatory label elements are declared appropriately is crucial for label compliance.

In short summary, there are five main elements required on all dietary supplements:

    1. Statement of identity,
    2. Net quantity of contents,
    3. Nutrition labeling (Supplement Facts),
    4. Ingredients list, and
    5. The name and place of business of the manufacturer, packer, or distributor.

The mandatory label elements have specific placement requirements, such as Country of origin declaration, allergen declaration, Proposition 65 statements, GMO/Bioengineered (BE) statements, and adverse event reporting information.

If a foreign language (other than English) is used anywhere on the label, all mandatory information must be in English and in the foreign language.
