What is BPH?
Benign prostatic hyperplasia is enlargement of the prostate that may contribute to lower urinary tract symptoms. Symptoms need assessment; they are not automatically caused by BPH.
Complementary approach evidence
NCCIH finds that saw palmetto generally performs no better than placebo for BPH urinary symptoms. Research on other supplements is limited or mixed.
Care decisions
Use an informed medical assessment for persistent or worsening symptoms. Supplements can have risks and should not delay necessary care. Consult NCCIH guidance.
