This page explains how we decide which products appear in our guides and how we compare them. We want you to be able to judge our recommendations for yourself.
Research-based, not lab-tested
Unless an article clearly says we tested a product ourselves, our recommendations are research-based. That means we compare products using published evidence, labels, manufacturer specifications, independent certifications and patterns in customer feedback. We never claim hands-on testing we have not done.
What we look at
Supplements
- Evidence: does research support the main ingredients for the stated purpose, at the dose provided?
- Dose transparency: are all ingredient amounts listed? We avoid proprietary blends.
- Safety: known side effects, stimulant content, interactions and who should avoid it.
- Quality signals: independent third-party testing (for example NSF, Informed Choice or USP) where it can be verified.
- Value: cost per effective serving compared with alternatives at the time of research.
Kitchen tools and fitness equipment
- Specifications that matter: for example capacity and resolution for scales; weight limit, speed range and deck size for walking pads.
- Usability: setup, app requirements, space and noise considerations from manufacturer information.
- Durability and support: warranty terms and recurring issues reported by buyers.
- Value: whether the features justify the cost for the intended user.
Badges such as “Best for beginners”
Badges describe who an option suits best, based on the criteria above. They are editorial judgements, not awards, and no brand can pay for one.
Editorial scores
Some product boxes may show an editorial score out of 10. A score is only shown when a product has been assessed against the criteria on this page. It is never copied from Amazon or any other retailer.
Prices and availability
We do not list prices because they change frequently. Use the “Check Price on Amazon” or “See Options on Amazon” buttons to see current prices, reviews and availability. Product information was correct when we last checked it, but manufacturers can change formulas and specifications, so always read the current label or listing.
