Editorial Standards
Prostate health is a category full of exaggerated claims, invented statistics, and fake reviews. These are the rules we hold ourselves to so you can trust what you read here — and hold us accountable when we fall short.
Who Writes This Site
Content is researched and written by the Supplement For Prostate editorial team. We are researchers and writers, not medical professionals, and we say so plainly rather than inventing credentials. Our job is reading the published research — clinical trials, systematic reviews, safety data — and summarizing it honestly. Nothing on this site is medical advice, and every article says so.
How We Grade Evidence
Every ingredient we cover is graded on a five-level scale, applied consistently across articles and product reviews:
| Grade | What it means | Example |
|---|---|---|
| Strong evidence | Consistent randomized-trial support for BPH urinary symptoms (e.g., a positive Cochrane review) | Beta-sitosterol |
| Moderate evidence | Positive controlled trials exist, but smaller or fewer | Pygeum, rye pollen extract |
| Mixed evidence | Meaningful positive AND null trials — we tell you both | Saw palmetto |
| Early-stage evidence | Mechanistic, population, or animal data; little or no RCT support | Boron, lycopene |
| Nutritional support | General-nutrition rationale rather than prostate-specific trials | Zinc, vitamin D3 |
When an ingredient's evidence is weak, we say "weak." When a popular product bets on a mixed-evidence ingredient, the review says so. When no supplement can do something — like shrink a prostate — we state that explicitly.
What We Never Do
- No invented statistics, user counts, or study citations
- No fabricated testimonials or reviewer personas
- No claims that supplements treat, cure, or prevent disease
- No "medically reviewed" badges without a real, named professional
- No hiding negative evidence about products we earn commissions on
How We Make Money — and Why It Doesn't Change Rankings
This site earns affiliate commissions: as an Amazon Associate we earn from qualifying purchases, and we earn commissions on some manufacturer links. Every affiliate link is disclosed on the page where it appears, and cloaked links are marked sponsored for search engines.
Commissions do not set our rankings — evidence and refund policies do. That's why our reviews include dedicated complaint roundups, why we recommend cheap single-ingredient products when they fit better, and why our buying checklist tells you how to evaluate any product, including ones we don't earn from. An unhappy buyer refunds — which helps nobody.
Where Product Data Comes From
Prices, ratings, and product details on review pages come from Amazon's official Product Advertising API and from product labels, refreshed regularly and displayed with an "as of" date where applicable. Ratings shown are Amazon customer ratings, attributed as such — not our own scoring.
Our Tools
The BPH Symptom Score Calculator implements the validated International Prostate Symptom Score (IPSS/AUA Symptom Index) without modification. It runs entirely in your browser: we do not collect, store, or transmit your answers.
Corrections
Found an error — a wrong dose, an outdated price, a claim that overreaches the evidence? Contact us and we will review it promptly. Substantive corrections are reflected in the article's last-updated date.
