What is known

Each outcome with its grade (how strong the evidence is, A to D), the size of the effect where the entry records one, and how often studies agree.

Conditions

How the entry reads its effect on diagnosed conditions: the direction first, then the grade. Never a substitute for the person who treats you.

  • Benign prostatic hyperplasia May improveTrial 8–12 weeksGrade C

What is uncertain

Read off the same rows as above. Nothing here is added that the entry does not itself record.

  • Thin evidence: BPH urinary symptoms (grade C).

Interactions

Documented pairings with supplements and medicines. A medicine on this list is a conversation for whoever prescribes it.

The evidence in words

What it is

Saw palmetto (Serenoa repens) berry extract is used for benign prostatic hyperplasia (BPH) urinary symptoms.

How it works

Proposed 5-alpha-reductase inhibition and anti-inflammatory effects on prostate tissue.

What the evidence shows

The large, well-run CAMUS trial and Cochrane reviews found no better than placebo for BPH symptoms; some smaller studies and specific lipidosterolic extracts are more favorable. Widely used, weakly supported.

How to use it

320 mg/day of a standardized lipidosterolic extract, 8–12 week trial.

Safety & interactions

Well tolerated; mild GI upset; may affect PSA interpretation and has mild antiplatelet action. Stinging Nettle — Common combined prostate formula.

Bottom line

Popular but largely placebo in the best trials. Worth a monitored trial for BPH; don't expect much.

How it is used

As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.

Standard
320 mg/day lipidosterolic extract.
