Prostate Health Supplements
An enlarged prostate (BPH) affects roughly 50% of men in their 50s and up to 80–90% by age 70. The compounds below are the most-researched non-drug options for urinary symptoms.
New urinary symptoms — weak stream, frequent urination, waking to urinate — can also come from prostatitis, prostate cancer, or bladder problems. Rule those out before starting any supplement protocol.
Top compounds
- Saw Palmetto
Most-used botanical for BPH; 320 mg/day standardized.
- Beta-Sitosterol
Best-evidence phytosterol; 60–130 mg/day for prostate.
- Pygeum africanum
Strong nocturia data; 100 mg/day.
- Stinging Nettle Root
Root (not leaf) — 360–600 mg/day, often stacked.
- Zinc
Prostate concentrates zinc; correct low zinc first.
Compare & guides
Saw palmetto, beta-sitosterol and pygeum overlap with 5-AR inhibitors, blood thinners and PSA-affecting drugs. Run your combo through the checker before adding a new compound.

What's the difference between BPH and prostatitis?
BPH is age-related enlargement of the prostate causing urinary symptoms. Prostatitis is inflammation, often from infection, and needs different treatment. Only a doctor can tell them apart.
Does saw palmetto really work?
The largest trials (STEP) found no benefit over placebo at the standard 320 mg dose. Smaller trials of the Permixon-brand extract show more consistent symptom improvement. Response is highly product-specific.
Can supplements shrink the prostate?
Not the way finasteride does. Supplements can improve urinary symptoms without measurably shrinking the gland.
Will these affect my PSA test?
Saw palmetto and finasteride-like compounds can lower PSA readings. Always tell your doctor what you take before a PSA test.
Can I stack saw palmetto with pygeum and beta-sitosterol?
Yes — they hit different pathways (5-alpha-reductase, inflammation, sterol metabolism). Combined protocols are common; keep each at the standard dose rather than doubling any one. Run the pair through DoseRoutine's interaction checker before adding a fourth.
Are prostate supplements safe with tamsulosin or finasteride?
Tamsulosin (Flomax) is usually fine to combine with saw palmetto or beta-sitosterol, but watch for dizziness. Finasteride already blocks 5-alpha-reductase — adding saw palmetto is redundant and may confuse a rising PSA. Tell your urologist about every supplement.
How long before I know if a prostate stack is working?
Give it 8–12 weeks and track your IPSS score, nocturia count, and urinary flow. If nothing has moved by 12 weeks at a standard dose, the compound is not your responder — swap, don't stack more.
