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 documented policy from the seller or the checkout platform. Where a claim cannot be traced to one of those, we do not publish it.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. Convert every ratio. A 10:1 extract at 100 mg is a 1,000 mg raw equivalent; a 20% standardisation at 12 mg is 2.4 mg of active. Ratios change conclusions in both directions.
3. Find the research dose. For each ingredient, the amount used in published human trials, and the form used.
4. Publish the gap. Whether it flatters the product or not.
5. Check the commercial terms. Pricing, guarantee wording and the checkout platform's own published policy.
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 We do not cite other affiliate pages, and we do not treat a seller's claim as evidence for itself.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 — Riboflavin
• NIDDK — weight management
• NCCIH — weight control and dietary supplements
• FDA — dietary supplements
• FTC — health products compliance guidance
• MedlinePlus — weight control
• CDC — losing weight
• Glucomannan weight-loss randomised trial

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 formula, and we say so rather than implying otherwise. They are also not weight-loss coaching: if you are managing obesity, diabetes or an eating disorder, that belongs with a clinician.

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 1% berberine dose, the 45 mg glucomannan, the payment-method guarantee inconsistency — are all findings a brand-controlled page would have removed.
