How We Review Supplements

Every supplement guide on FactoWiki follows the same review process, whether or not a link on the page earns us a commission.

1. We research the ingredients

We start with the formula, not the marketing. For each named ingredient we look at what published research actually shows — including its limits — and link to sources such as PubMed, the NIH Office of Dietary Supplements and NCCIH so you can read them yourself.

2. We check the label and safety

We note the form, whether per-ingredient doses are disclosed or hidden in a proprietary blend, and any interactions or groups who should avoid the product. Safety comes before persuasion.

3. We review price, packages and the guarantee

We summarise current pricing and the refund window, and remind you to confirm the latest terms on the official seller page, because these change.

4. We compare honest alternatives

We point to other reasonable options for the same goal — including doing nothing, or seeing a doctor — so a guide never reads as if one product is your only choice.

What we don't do

We do not invent customer reviews or star ratings, we do not use fake doctor personas, and we do not let an affiliate relationship change our assessment. Claims are written in structure/function language ("may support"), never as cures.
