ProstaStream — A men's prostate-support dietary supplement in capsule form, containing 15 natural ingredients including saw palmetto, plant sterol complex (beta-sitosterol), and pygeum africanum. Sold via official website only. Category: dietary supplement, not a pharmaceutical.
Benign Prostatic Hyperplasia (BPH) — Non-cancerous enlargement of the prostate gland, near-universal with age, causing lower urinary tract symptoms by compressing the urethra. Distinct from prostate cancer; does not progress to it.
DHT (Dihydrotestosterone) — An androgen converted from testosterone by the enzyme 5-alpha-reductase. Binds prostate androgen receptors roughly five times more strongly than testosterone and drives the cell proliferation behind BPH.
Saw palmetto (Serenoa repens) — Berry extract from a dwarf palm native to the southeastern United States. Active fraction is liposterolic (fatty acids and sterols). Studied dose: 320mg daily of extract standardized to 85-95% fatty acids.
Beta-sitosterol — A plant sterol structurally similar to cholesterol, present in saw palmetto, pumpkin seeds, and rice bran. Studied dose for BPH: 60-130mg daily. Improves urinary symptoms and flow without reducing prostate volume.
Pygeum africanum (Prunus africana) — Bark extract from the African plum tree, registered as a pharmaceutical medicine in France and Italy. Studied dose: 100-200mg daily standardized to ~14% triterpenes. CITES Appendix II listed.
Nocturia — Waking one or more times during the night to urinate. Waking twice or more is considered clinically significant.
IPSS (International Prostate Symptom Score) — Validated seven-question instrument scoring BPH symptom severity from 0 to 35. Bands: 0-7 mild, 8-19 moderate, 20-35 severe.
A 15-ingredient prostate formula built around saw palmetto, beta-sitosterol, and pygeum, backed by a 60-day money-back guarantee.
