Synopsis

Rating (out of 5): 3

Sterols, particularly beta-sitosterol, are plant-derived compounds structurally similar to cholesterol. They have been studied for their effects on prostate health, especially in the context of benign prostatic hyperplasia (BPH), a common non-cancerous enlargement of the prostate gland in older men. Several randomized, placebo-controlled clinical trials have found that beta-sitosterol can modestly improve urinary symptoms and flow measures in men with BPH. The mechanism is believed to involve anti-inflammatory effects and potential inhibition of 5-alpha-reductase, an enzyme involved in prostate tissue growth.

A 1999 meta-analysis published in the journal Lancet reviewed four studies and concluded that plant sterols improve urinary symptoms and flow measures, although the duration of studies was limited (typically less than six months) and long-term safety and efficacy remain less well established. Guidelines from bodies such as the American Urological Association do not currently recommend sterols as first-line therapy, but acknowledge their use as a complementary option based on clinical trial evidence.

In summary, there is moderate scientific evidence that sterols—primarily beta-sitosterol—can support prostate health by alleviating urinary symptoms associated with BPH, though the effect size is modest and more research is needed on long-term benefits and safety.
