Methodology
This page explains how DrugsGeek assesses health products and the evidence behind them.
What we look at
- Ingredients and doses. What is in the product, at what dose, and whether the label discloses amounts or hides them in a “proprietary blend”.
- Evidence for each ingredient. Whether studies in people support the claimed benefit at the dose in the product, how large and independent those studies are, and whether results have been replicated.
- Safety. Known side effects, interactions, liver-injury reports, warnings for pregnancy, children or people with particular conditions, and any regulatory action.
- Regulatory and advertising record. FDA warning letters, recalls, FTC actions and advertising-review decisions about the product or its seller, where they exist.
- Price and value. What a typical course costs compared with simpler alternatives that have similar or better evidence, including subscription and “free trial” terms.
What we do not do
- We do not test products ourselves or run laboratory analyses.
- We do not use star ratings or numerical scores.
- We do not base conclusions on customer reviews or ratings on retail sites.
How recommendations work
Buying guides explain how to choose within a product category and may point to example products that fit the criteria, with a link to Amazon. These are editorial judgements based on the factors above, not guarantees, and they can change when the evidence or the products change.
