How to check
How do you find out who owns a supplement brand?
To find out who owns a supplement brand, start with the product label, which must list the name and place of business of the manufacturer, packer, or distributor. Then compare that name with information on the brand’s website terms of use and privacy policy, business registrations, and any distributor lines printed on the packaging.[1][8] Because supplements are not approved by the federal regulator before they are sold, ownership and safety claims are not pre-vetted in the way prescription drugs are.[1] You can also search federal databases for adverse event reports and regulatory warning letters related to the company or product.[13][14]
Supplements are sold without pre-approval
In the United States, dietary supplements are regulated differently than prescription and over-the-counter drugs. The Food and Drug Administration does not approve dietary supplements or their claims before they go on the market, and companies are responsible for making sure their products are safe and properly labeled.[1] This means the government does not pre-vet who owns a brand or whether its marketing claims are accurate before you see it on a shelf.
Reading the label for ownership clues
Every packaged dietary supplement is required to list the name and place of business of the manufacturer, packer, or distributor on the label.[12] The same label often includes a line such as "distributed by" or "manufactured for," which can point to the business behind a brand name.[1] If a practitioner is selling supplements under their own name or clinic brand, that practitioner is both recommending the product and participating in the business that sells it.
Using websites and business records
Brand ownership often surfaces in the company’s own documents. Website terms of service, privacy policies, and contact pages frequently identify the legal entity that owns or operates the brand.[8] Public business registrations, such as state-level corporate filings or "doing business as" records, can also show which company stands behind a consumer-facing supplement label.[1] These pieces of information can be compared to see whether the brand name on the front of the bottle matches the business entity behind it.
Checking federal safety and enforcement records
Several federal tools can help you look for safety and enforcement signals linked to a supplement brand. The FDA maintains information on dietary supplements, including how they are regulated and what responsibilities companies have, on its dietary supplements portal.[1] The FDA also posts public warning letters, which you can search by company name or product name to see whether a firm has received regulatory correspondence about its supplements.[2] Adverse events related to supplements are reportable to federal authorities, and those reports contribute to ongoing oversight of products already on the market.[1]

How can I see if a supplement brand has received an FDA warning letter?+
FDA warning letters are posted in a public database that you can search by firm name, product, or other keywords.[2] Searching this database can show whether a company has received regulatory correspondence about its supplements, which may relate to labeling, claims, or other compliance issues.[2]
