Beta-sitosterol

Also: phytosterols, plant sterols (beta-sitosterol)

A plant sterol with short-term evidence for benign prostate symptoms.

Evidence by condition

Each grade reflects the research for Beta-sitosterol and that condition specifically.

Beta-sitosterol is the plant sterol behind several prostate supplements. It improves BPH urinary symptoms and flow short-term — better evidence than saw palmetto for this use — though the trials are small and dated, and it does not shrink the prostate.
