Buying guides
How we rank weight-management products
Every ranking starts with the same criteria: verified ingredient and dosage facts, third-party certifications, cost per serving, and the return policy. This page explains how we weigh them and how you can apply the same checks yourself.
Category rankings
Category standouts and why they earned their place
Rankings are grouped by product category. Each entry notes the criterion that set it apart, and none reflects a payment or placement arrangement.
Meal replacements
Highest transparency in labeling
Ranked first for complete ingredient panels, listed per-serving amounts, and third-party testing statements that can be verified on the manufacturer's site.
Fiber supplements
Strongest value per serving
Ranked for a lower cost per serving at a clearly stated dose, with a published return window that allows a fair trial period.
Appetite and hydration aids
Clearest claims discipline
Ranked for avoiding outcome promises. Its label describes ingredients and serving size without implying guaranteed weight loss.
Label checklist
Six steps to vet a supplement label
01
Check ingredient amounts
Confirm each active ingredient lists an amount per serving, not just a proprietary blend total.
02
Compare against stated thresholds
Look up the dose used in published studies and note whether the product's amount is comparable.
03
Look for third-party testing
Identify the testing body named on the label and verify the certificate or report is publicly available.
04
Calculate cost per serving
Divide the total price by the number of servings, then compare products on the same basis.
