Why Saw palmetto berry/fruit extract (lipophilic: CO2, hexane or oil; usually standardized to fatty acids/sterols) is unrated
The form used in the cited trials (Barry 2011), which found no benefit over placebo at up to 3x the standard dose. Per NCCIH's summary of the 2023 Cochrane review (27 studies), reviewers analyzed hexane-extracted products separately from other products and found no difference in BPH symptoms between them, so no tiering between extract types is supported; brand-to-brand compositional variation is documented but not linked to outcomes.

Why Saw palmetto berry/fruit powder is unrated
Ground berry is a different material from the lipophilic extract used in the cited trials; no verified human comparison of powder vs extract.
