What can you say about berberine in your ads and on your site?

The library gives no supported wording for berberine, because no listed source supports one at a dose. Avoid wording that names or implies a disease, a drug or a treatment, such as “Lowers blood sugar, or helps manage diabetes”.

Not legal advice. This guide shows the wording that published evidence supports at a daily dose; it is not a ruling on any claim. Your own product, its form and dose, and your own evidence still need to match the wording you use.

Health Canada’s monograph list (checked 2026-10-14) has no monograph for it, no ODS fact sheet among those read covers it, FDA’s lists show no health claim for it, and Regulation (EU) No 432/2012 has no claim for it. Until a listed source covers it, the library supports no wording for it.
