Do Supplements Need FDA Approval? How Supplements Are Regulated

7 min read

No: under US law the FDA does not have the authority to approve dietary supplements for safety and effectiveness, or their labels, before they are sold. That does not make supplements unregulated. Here is what the rules actually require, from the FDA's own guidance.

Researched against our directory of 195 makers, maker-published documents and official sources. Last reviewed October 2026. Figures change, so confirm with the maker before budgeting.

Who is responsible

Under the Federal Food, Drug, and Cosmetic Act, dietary supplement companies are responsible for making sure their products meet safety standards and are labeled lawfully. The FDA acts after products are on the market: it inspects manufacturing facilities, reviews labels and websites, and can take action against unsafe or mislabeled products. A product intended to treat, cure, prevent or alleviate a disease is regulated as a drug, even if it is labeled as a supplement.

What the law does require

Manufacturing practices: anyone who manufactures, packages, labels or holds dietary supplements must follow current good manufacturing practice under 21 CFR part 111, which covers identity, purity, strength and composition. See GMP certified makers.
Facility registration: facilities that manufacture, process, pack or hold food, including supplements, must register with the FDA and renew every other year. See what FDA registration means.
New dietary ingredients: an ingredient not marketed in the US before October 15, 1994 generally needs a notification to the FDA at least 75 days before the product is marketed.
Claims: a structure/function claim needs substantiation, a standard disclaimer, and a notification to the FDA within 30 days of first marketing.

"FDA registered" is not "FDA approved"

A maker that says it is FDA-registered means its facility is registered, which is a legal baseline, not an approval or inspection result. To check a maker's quality, look for an independent audit such as NSF GMP certification, and see how we grade evidence on our methodology page.

Supplements and FDA approval: FAQs

Can supplements be sold without FDA approval?

Yes. The FDA does not have authority to approve dietary supplements before they are marketed. Companies must still follow cGMP, register their facilities, label products correctly and notify the FDA of new dietary ingredients.

Why does the FDA not approve supplements?

Because the law does not give it that power. Under the Dietary Supplement Health and Education Act of 1994, companies are responsible for the safety and labeling of their products, and the FDA acts after products reach the market.

Does the FDA certify supplements or manufacturers?

No. Facilities register with the FDA, which is a legal requirement, not a certification. Independent bodies such as NSF audit facilities against GMP standards and publish the results.

Who regulates the supplement industry?

The FDA, under the Federal Food, Drug, and Cosmetic Act as amended by DSHEA. It inspects facilities, reviews labeling and acts against unsafe or mislabeled products.

How do I know if a supplement is FDA approved?

Supplements are not FDA approved, so a claim that one is should be treated with caution. 'FDA registered' refers to the facility's registration, not the product.
