Beta-sitosterol

别名: plant sterol, phytosterol

Beta-sitosterol is the most common plant sterol, found in nuts, seeds and vegetable oils. It is used for urinary symptoms with an enlarged prostate and as part of sterols that lower LDL cholesterol.

用途

urinary symptoms with an enlarged prostate – moderate evidence (improved symptoms and urine flow in older reviews; does not shrink the prostate)
lowering LDL cholesterol – strong evidence for plant sterols as a group (EFSA-approved claim at 1.5–3 g sterols a day with food)

For LDL you need gram doses – the small amounts in prostate capsules are not enough for cholesterol.
