Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Sterols, particularly plant sterols such as beta-sitosterol, have been studied for their role in supporting prostate health, especially in men with benign prostatic hyperplasia (BPH). Several randomized controlled trials and meta-analyses have demonstrated that beta-sitosterol can improve urinary symptoms and flow measures in men with mild to moderate BPH. The proposed mechanism involves modulation of inflammatory pathways and possible inhibition of 5-alpha-reductase, an enzyme involved in prostate enlargement. While the effect size is generally modest and does not reduce prostate size, symptom relief has been consistently documented for some preparations.

Most of the research has focused on beta-sitosterol, the most common phytosterol found in supplements, rather than a broad category of "sterol (unspecified)." The evidence base is sufficiently robust to warrant a moderate rating, though variability in study quality and the lack of long-term safety data limit stronger recommendations. Notably, sterols are not considered a treatment for prostate cancer and should not replace conventional therapies for significant urologic conditions. Overall, plant sterols, especially beta-sitosterol, are scientifically validated to provide mild to moderate symptomatic relief for BPH, supporting their use for prostate health.
