Why Pumpkin Seed Oil for Hormones
Pumpkin Seed Oil plays a supporting role in hormones. Rich in phytosterols (especially beta-sitosterol), zinc, and fatty acids. Multiple RCTs support 320–500 mg/day for BPH symptom improvement.
What dose to look for
Clinical studies typically use 320–1000 mg of pumpkin seed oil. 320–500 mg/day extract used in BPH/prostate RCTs (GRANU study: 500 mg/day). 320 mg commonly combined with saw palmetto. Crude seed oil/powder doses are higher (1–2 g). Products below this range may not deliver meaningful results.
What the research says

Clinical research on Pumpkin Seed Oil (Cucurbita pepo)
WEAK — prostate/BPH + hair via 5-AR mechanism; small, preliminary trials · 320 mg/day (BPH trials) — preliminary, not a validated hormone dose
- •RCT (76 men, 24 weeks): pumpkin seed oil increased hair count vs placebo in mild-to-moderate androgenetic alopecia — a single small trial, mechanism attributed to phytosterol 5-alpha-reductase inhibition.
- •Single-blind RCT vs tamsulosin reported pumpkin seed oil relieved BPH urinary symptoms with no side effects — but it was not as effective as the drug, and the trial lacked a placebo arm.
- •The 5-AR / antiandrogen mechanism is plausible but the human evidence is thin and preliminary; no large placebo-controlled confirmation for either prostate or hair outcomes.
