Overview

Amazon announced a new enforcement policy that bans inflated weight claims on dietary supplement listings, giving sellers until March 31 2026 to adjust their product pages. The rule targets the practice of using raw‑material conversion math to present ingredient amounts far larger than what is actually contained in the capsule or powder. Non‑compliant listings will be removed after the deadline, making the change critical for any seller in the supplement category.

Key Points

• Raw‑material equivalence prohibited — Listings can no longer claim “10,000 mg turmeric” when the product only holds 500 mg of standardized extract.
• Ingredient‑specific weights required — Every weight figure must be tied to a named ingredient, eliminating vague statements such as “high potency”.
• Portion context mandatory — Sellers must indicate whether the weight applies per serving, per tablet, or per full bottle.
• Label consistency enforced — Titles, bullet points, descriptions, and backend keywords must match the exact numbers shown on the Supplement Facts panel.
• Full label images compulsory — Product photos must display the complete Supplement Facts panel, including lot numbers, matrix codes, and manufacturer details.
• Scientific conversions still allowed — Legitimate dual‑unit listings (e.g., Vitamin D 5,000 IU = 125 µg) are acceptable when both units appear on the label.

How the New Weight Claim Policy Works

1. Identify inflated claims — Run a catalog audit to flag any listing that uses raw‑material equivalents; for example, a 600 mg green tea extract marketed as “12,000 mg leaf extract”.
2. Verify Supplement Facts — Cross‑check each product’s label image to ensure the weight numbers on the page match the amounts printed on the actual Supplement Facts panel. A supplement showing 250 mg of calcium carbonate must not be described as “5,000 mg calcium”.
3. Rewrite listing content — Update titles, bullet points, and product descriptions so that every weight reference is tied to a specific ingredient and includes the correct serving context. For instance, change “10,000 mg turmeric per bottle” to “500 mg turmeric extract per capsule (equivalent to 10,000 mg raw turmeric) – disclosed only in the label”.
