What we check
- Ingredients and safety: whether the ingredients are recognized and researched for what the product is meant to do, and any safety cautions.
- Label transparency: whether there's a Supplement Facts label and how much of each ingredient is disclosed.
- Value for money: the real cost per day on the best package, shipping, and whether the "was" prices are just marketing anchors.
- Guarantee: the refund window, what's covered and how easy it is to claim.
- Buying experience: a known retailer, secure checkout, one-time purchase without hidden subscriptions, shipping and support.
- What to know before you buy: sales-page claims that go beyond the label, inconsistencies and groups who should talk to a doctor first. We report these in every review.
How we score
| Category | Weight |

Each category is scored from 1 to 5 and the final score is the weighted average. As a guide: 5 means research-backed ingredients at meaningful doses, a full label with every dose, a cost of about $1.20 a day or less, a 365-day guarantee and a smooth one-time checkout; 3 means some of those are missing or unclear. The score rates the product and the offer as a buyer gets it; issues on the sales page are reported in each review under "What to know before you buy". A score is our editorial opinion, not a clinical result. Method updated November 12, 2026.
What we don't claim
We don't claim a product will work for you, and we never invent customer experiences. If we haven't bought and tested a product, we say so. Prices and terms are checked on the date shown on each review and can change.
