Tom’s Weight LossRankings

Supplements

Supplements that publish a full label

The products in this directory where every active ingredient carries a stated amount, rather than hiding behind a proprietary blend.

This is the one list here that measures something objective. A product either states how much of each active it contains or it does not, and the ones that do are the only ones you can compare against research, check against your medication, or judge on value. It is not a quality ranking — a fully labelled product can still be a poor choice — but it is the difference between a decision and a guess.
