Editorial Policy and Review Methodology

Every claim on this site is traceable to one of three things: the Supplement Facts panel, published human research, or a statement made by the seller. Where a claim cannot be traced to one of those, we do not publish it.

How we assess a supplement

1. Read the panel first. Ingredients and amounts before any marketing copy.
2. Do the arithmetic. Add printed doses and compare against the declared blend total.
3. Find the research dose. For each ingredient, the amount used in published human studies.
4. Publish the gap. Whether it flatters the product or not.
5. Cross-check the seller network. Prices, guarantee terms and ingredient lists across every page using the brand name.
6. Medical review. A pharmacist checks dose figures, interaction notes and safety wording.
7. Date it. Every page carries a published and updated date.

Our sourcing standards

We cite primary sources — government health agencies, peer-reviewed research indexes and regulator guidance. We do not cite other affiliate pages, and we do not treat a seller's claim as evidence for itself. The sources we lean on most often:

• NIH Office of Dietary Supplements — Vitamin B6
• National Institute on Aging — memory loss and forgetfulness
• NCCIH — green tea
• FDA — dietary supplements
• FTC — health products compliance guidance
• MedlinePlus — memory

Corrections

If a dose figure, price or policy statement on this site is wrong, tell us via the contact page and we will correct it and note the change. Product labels, pricing and guarantee terms change without notice, which is why every page tells you to confirm at checkout and to read the panel on the bottle you receive.

What our reviews are not

They are not medical advice, and they are not a substitute for talking to a pharmacist or doctor about your own situation and medication. They are not clinical trials of the finished product — no such trial exists for this blend, and we say so rather than implying otherwise.

Independence

We earn affiliate commission on qualifying purchases. No manufacturer reviews, approves or pays for our content, and no brand has editorial input. The critical findings published here — the unitemised 109 mg, the below-research doses, the conflicting formula lists across the seller network — are all findings a brand-controlled page would have removed.
