Yes, saw palmetto (Serenoa repens) is the most clinically studied herb for benign prostate hyperplasia (BPH) support. Studies show that 320 mg of standardized extract per day reduces frequent urination, nighttime urination, and improves urine flow. Saw palmetto inhibits the 5-alpha-reductase enzyme, which converts testosterone into DHT — a hormone promoting prostate enlargement.

Effective supplements for potency include L-arginine (blood vessel dilation), maca (libido and energy), zinc (testosterone levels), and tribulus terrestris (sexual function). L-arginine at 3,000-5,000 mg per day promotes nitric oxide production, which improves circulation. Maca at 1,500-3,000 mg per day has shown libido improvement within 6-8 weeks.

Yes, zinc is directly linked to testosterone production. Zinc deficiency leads to decreased testosterone levels, as documented in multiple studies. Men are recommended 15-30 mg of zinc per day. Zinc also supports prostate health and sperm quality. Excessive intake (over 40 mg) can impair copper absorption — do not exceed the recommended dose.

See a doctor if you experience blood in urine, sudden urination difficulty, severe pelvic pain, or persistent erectile dysfunction that does not respond to lifestyle changes. Supplements are intended for prevention and mild symptom support — they do not replace medical treatment. Men over 50 should have regular prostate check-ups.

Most potency supplements require 4-8 weeks of consistent use before results appear. L-arginine's circulation-improving effects may appear sooner — within 2-3 weeks. Saw palmetto's relief of prostate symptoms typically takes 4-6 weeks. Maca's libido-supporting effect appears after 6-8 weeks.
