==FDA warnings about dietary supplements==
Between 2018 and 2023, the FDA issued 29 [[FDA warning letter|warning letters]] to American manufacturers of [[dietary supplement]]s for making false claims of anti-disease effects from using  products containing curcumin.<ref name="fdawarn">{{cite web |title=Warning Letters: Curcumin (search term) |url=https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/compliance-actions-and-activities/warning-letters |archive-url=https://web.archive.org/web/20190428002400/https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/compliance-actions-and-activities/warning-letters |url-status=dead |archive-date=April 28, 2019 |publisher=US Food and Drug Administration |access-date=23 April 2023 |date=23 April 2023}}</ref> In each letter, the FDA stated that the supplement product was not an [[prescription drug|approved new drug]] because the "product is not generally recognized as safe and effective" for the advertised uses, that "new drugs may not be legally introduced or delivered for introduction into interstate commerce without prior approval from FDA", and that the "FDA approves a new drug on the basis of scientific data and information demonstrating that the drug is safe and effective".<ref name=fdawarn/>
