Start here: supplements are not FDA-approved
The FDA approves drugs, not dietary supplements. Supplements reach the market without pre-sale evaluation of their claims or effectiveness; the agency's role is largely post-market. Any supplement listing claiming approval is misusing the term — a fact worth weighting heavily, because a seller careless with that line is careless by choice.
'Made in an FDA-registered facility'
Food and supplement manufacturing facilities are required to register with the FDA. Registration is an administrative listing, not an endorsement, inspection grade or product review. The phrase is technically true of virtually every legal US supplement — which is precisely why it certifies nothing distinctive about the one you're holding.
GMP and cGMP claims
Current Good Manufacturing Practice regulations genuinely bind supplement manufacturers — they govern identity testing, cleanliness and record-keeping. 'GMP-certified' badges usually reference third-party audits of the facility. This is a floor about manufacturing hygiene, not evidence the formula works; a perfectly manufactured underdosed product is still underdosed.
'Clinically proven' and borrowed studies
This phrase almost always refers to studies on an individual ingredient — often a branded form, at a specific dose — not on the finished product. The questions that expose it: proven for what outcome, at what dose, and does this product contain that dose? Finished-product trials in this industry are rare enough that we flag their absence in every review.
'Doctor formulated' and expert branding
An unverifiable credential attached to marketing copy adds nothing checkable. Where a real, named clinician with a verifiable identity stands behind a formula, that's notable; where the doctor is a stock photo or an unsearchable name, treat the claim as decoration. Article Heaven applies the same rule to itself — we don't invent reviewer credentials.
What's actually worth trusting
Disclosed ingredient forms and amounts; doses matching published research; third-party testing with lot-level certificates; a checkout whose refund terms are stated plainly; and claims phrased within legal structure/function limits. Trust accumulates from verifiable specifics, never from badges.
