How We Score Supplements
Our reviews follow one consistent, transparent rubric. Here is exactly how we evaluate every product — and why our scores are our own editorial opinion, not customer star aggregates.
Our scoring rubric
Every supplement we review is scored on five weighted dimensions. The final editorial score (out of 5) is a weighted average. We do not accept payment to change a score, and an affiliate relationship never moves a product up our list.
| Dimension | Weight | What we look at |
|---|---|---|
| Ingredients & dosing | 30% | Are the active ingredients recognizable, and do the doses align with the doses used in published research on those ingredients? |
| Formulation quality | 25% | Strain/ingredient selection, delivery format, manufacturing standards (e.g. GMP-registered facility), and label transparency. |
| Value for money | 20% | Price per serving versus comparable products, plus bundle pricing and shipping. |
| Guarantee & risk | 15% | Length and terms of the money-back guarantee, refund friction, and buyer protection. |
| Transparency & reputation | 10% | Clear labeling, honest marketing, and the balance of publicly available user feedback. |
What our scores are — and are not
Our score is the editorial opinion of our team based on the rubric above. It is not an average of customer reviews, and we never display invented star ratings or fabricated testimonials. When we quote user feedback, it is clearly labelled as an individual experience, and results vary from person to person.
Our limits (honest disclosure)
We are an independent editorial team, not a clinical laboratory. We do not run our own lab assays or clinical trials, and we do not claim medical review by a licensed clinician unless a named professional has actually reviewed the piece. Where we cite science, we cite published studies on the individual ingredients — which is not the same as proof that a finished branded formula produces a specific result.
How we handle affiliate links
Some links on our reviews are affiliate links; if you buy through them we may earn a commission at no extra cost to you. This funding never determines our rankings or scores. See our Editorial Policy for the full standards.
