How Supplement and Longevity Scams Work — And How to Protect Yourself

What are the most common supplement scams?

Supplement fraud rarely looks like fraud. It looks like science — a study citation, a certificate graphic, a doctor in a white coat. These are the six patterns that account for most consumer complaints.

The FTC publishes enforcement actions against health-claim advertisers at its health products compliance guidance, and the FDA maintains a public list of tainted supplement products found to contain undeclared drug ingredients.

How can you tell if a supplement brand is legitimate?

Legitimacy is verifiable. Every item below is something you can check yourself in a few minutes, before you spend anything.

• Third-party certification: look for an NSF Certified for Sport, USP Verified, or Informed Sport mark, then confirm the specific product in the certifier's own public database — not just the logo on the box.
• A real physical address and a working phone number or support email that a human answers. A PO box plus a contact form only is a warning sign.
• Certificates of analysis (COAs) published per batch, with the lot number on your bottle matching a downloadable COA showing identity, potency, and contaminant testing.
• No disease claims. Lawful supplement marketing cannot claim to treat, cure, or prevent a disease. Any product promising to cure, reverse, or replace medication is making an illegal claim.
• Transparent pricing: a clear one-time price, no forced subscription, and a refund policy stated in plain language with a real window.
• A traceable company history — registered business name, years in operation, and recall or warning-letter history you can search.

Verify certification marks directly: NSF Certified for Sport, USP Verified, and Informed Sport each publish a searchable product list. In Canada, check the licence number on the label against Health Canada’s Licensed Natural Health Products Database.

What are the red flags on a product label?

The label is the part a scam brand controls least well, because regulators have specific requirements for it. Turn the bottle around before you buy.

• “Proprietary blend” with only a total milligram figure and no per-ingredient amounts
• No lot or batch number, or no expiry date printed on the bottle
• Claims to “cure”, “reverse”, “detox”, or “replace” a prescription medication
• No manufacturer name or address on the label at all
• “Research use only” or “not for human consumption” wording on a product marketed to consumers
• Serving size that quietly requires 4–6 capsules to reach the advertised dose
• Ingredient names invented for marketing that do not appear in any ingredient database
• No supplement facts panel, or a panel that does not add up to the stated capsule weight

The FDA explains what a compliant dietary supplement label must contain, including the supplement facts panel and manufacturer details.

Why does keeping a record of what you take matter?

A record is not admin busywork — it is the evidence layer that makes every other protection on this page work. Four concrete reasons:

• Returns and refund disputes. Card issuers decide disputes on documentation. A dated list showing purchase date, product, lot number and when you stopped taking it is far stronger than a recollection.
• Spotting which product caused a reaction. If you started three things in the same month, a dated log is the only way to isolate the one that lines up with the symptom.
• Catching duplicate ingredients. Stacked products frequently repeat the same ingredient, so people unknowingly take several times the intended amount across separate bottles.
• Showing a clinician an accurate list. Pharmacists and physicians can only check for interactions against what you can actually tell them — brand, ingredient, dose and frequency.

If you take several products at once, a dedicated tracker makes this much easier — we use DoseRoutine, a supplement and longevity routine tracker, to keep a dated record of every product, dose and batch.

What should you do if you have already been scammed?

1. Start the chargeback clock immediately. Most card networks allow a dispute within 120 days of the transaction (or of the expected delivery date), and many issuers apply shorter internal windows. Call your card issuer, state “unauthorised recurring charge” or “goods not as described”, and ask for the dispute in writing.
2. Cancel the recurring authorisation, not just the order. Cancelling on the merchant's site often does not stop the card mandate. Ask your issuer to block future charges from that merchant, and keep the reference number they give you.
3. Report it to the regulator. In the US, file at ReportFraud.ftc.gov and report adverse reactions or dangerous products to the FDA. In Canada, report to the Canadian Anti-Fraud Centre and to Health Canada for product-safety issues.
4. Report the seller on the platform that carried the ad. Report the ad or storefront on the platform (Meta, TikTok, Amazon, Instagram) and on any marketplace that listed it. Platform reports are what get repeat sellers removed.
5. Keep every record. Order confirmation, ad screenshot, product photos showing the lot number, and your dated log of what you took and when. Disputes are won on documentation.

File in the US at ReportFraud.ftc.gov and report product problems through FDA MedWatch / Safety Reporting. In Canada, contact the Canadian Anti-Fraud Centre and report health-product issues to Health Canada MedEffect.
