Merchient’s ingredient library

What can you say about oat beta-glucan in your ads and on your site?

The library supports 3 wordings for oat beta-glucan; the strongest is “Helps maintain normal blood cholesterol levels” (strong, 3-10 g beta-glucan a day). Avoid wording that names or implies a disease, a drug or a treatment, such as “Lowers cholesterol, or reduces heart disease risk, outside FDA’s authorized wording and conditions”, and keep “When taken with a meal, helps reduce the rise in blood sugar after that meal” off Meta ads.

Also called: Oat beta glucan, Beta-glucan from oats, Oat bran beta-glucan, Barley beta-glucan

Claims Facts

Ingredient: Oat beta-glucan

Wording to avoidReason
“Lowers cholesterol, or reduces heart disease risk, outside FDA’s authorized wording and conditions”FDA’s 2000 rule gives ‘lowers cholesterol’ as a disease claim (page 1015); heart disease risk belongs only in the authorized health claim (21 CFR 101.81).Disease
“Lowers blood sugar in diabetes, or helps manage diabetes”Names a disease.Disease
“When taken with a meal, helps reduce the rise in blood sugar after that meal.” Meta ads onlyBlood sugar is a health-condition claim on Meta, so this wording stays off Meta ads, as chromium’s blood glucose 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.
