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

The library supports 2 wordings for chromium; the strongest is “Helps maintain normal blood glucose levels” (strong, 6-500 µg a day). Avoid wording that names or implies a disease, a drug or a treatment, such as “Lowers blood sugar, or helps manage diabetes”, and keep “Helps maintain normal blood glucose levels” off Meta ads.

How strong the evidence is

Strong evidence: At least two listed sources support it independently at a comparable dose and form, and none disagrees.
Moderate evidence: One listed source supports it as an evidence-based use at that dose, and no listed source disagrees.
Limited evidence: The only support is traditional use, the sources disagree, or the source itself calls the evidence weak.

Wordings to avoid

What to leave out.

Claims Facts

Ingredient: Chromium

Wording to avoid	Reason
“Lowers blood sugar, or helps manage diabetes”Names a disease. Maintaining normal blood glucose is structure-and-function wording; lowering blood sugar or managing diabetes is not.	Disease
“Reverses insulin resistance or prediabetes”Names medical conditions. FDA’s only qualified claim here is for chromium picolinate, with set wording (see fda_health_claims).	Disease
“Treats PCOS”Names a disease (polycystic ovary syndrome).	Disease
“Helps maintain normal blood glucose levels.” Meta ads onlyBlood sugar is a health-condition claim on Meta, so this wording stays off Meta ads, as potassium’s blood pressure wording does (library decision of 2026-10-15; Meta’s ad policies were not read). It stays supported wording for pages.	Disease

Disease: names or implies a disease. Drug: names a drug or presents the product as one. Treatment: promises to treat, cure or prevent a condition. Meta ads only: keep it out of Meta ads; on your own site it is supported wording.
