How We Review Supplements: Our Methodology

Every review on this site follows the same process, so you can judge how much weight to give it.

1. Official information first

We read the manufacturer's official page, label and refund policy, and record the date we checked them. Prices and guarantees change, so we re-check regularly and show the review date on each page.

2. Ingredient evidence

For each named ingredient we look at what independent sources say, starting with the U.S. National Institutes of Health (NCCIH, Office of Dietary Supplements and the relevant institute) and peer-reviewed research. When a formula hides doses in a proprietary blend, we say so, because it limits what anyone can conclude.

3. Safety and interactions

We flag known side effects, drug interactions and groups who should avoid a product or talk to a doctor first, such as people on blood thinners, pregnant women or people with chronic conditions.

4. Realistic expectations

We separate what a supplement may support from what it cannot do. No supplement cures disease, and we never present one as a replacement for medical diagnosis or treatment.

5. Complaints and buying risks

We look at the pattern of complaints (shipping, refunds, expectations) and at buying risks such as unauthorized resellers and counterfeit listings.

What we do not do

• We do not publish invented testimonials or fake personal tests.
• We do not accept payment to change a verdict or a ranking.
• We do not give medical advice.
