How to Verify a Supplement Seller

Follow the identity across the transaction

Write down the exact domain, seller name, product name, and support route before ordering. Then compare those details with the checkout and receipt. Differences are not automatically fraudulent—for example, a payment processor can have a different name—but unexplained differences deserve clarification.

Do not use a copied product logo as your only evidence. An image can be reused by legitimate publishers and by unrelated sellers. For FEMICORE, our purchase-route guide documents the limited connections we could observe.

Look for information you can actually use

• A readable current label, including other ingredients and cautions.
• A clear total payable and package quantity.
• A support route for product questions and one for billing questions.
• Return conditions that explain the process rather than only a headline promise.
• A receipt identifying what was ordered.

Save these records before the page changes. If you ask a question, retain the answer with your receipt. A written statement can help resolve confusion about which terms were offered.

Separate business checks from scientific checks

A legitimate payment process does not prove that a health claim is supported. FDA explains that supplements do not undergo the same premarket approval process as drugs.

Ask for the exact study behind a claim. Check whether it evaluates the finished product rather than one ingredient. For composition testing, ask what batch and tests a certificate covers. A document about ingredient identity is not a clinical trial, and a clinical paper is not a batch certificate.

When details remain unclear

Pause the purchase until the question is answered. You do not need to label a seller fraudulent to decide that the documentation is insufficient for your needs. Compare another route, speak with a pharmacist about the formula, or choose not to buy.

The next practical step is to read the label and compare the full cost. Those checks are useful even after you are comfortable with the seller identity.
