HelloPharmacist Scorecard of Pumpkin Seed Oil 1000 mg by NOW
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains 3 active ingredients: pumpkin seed oil, plus polyunsaturated fat and monounsaturated fat. The pumpkin seed oil is the star — it's the concentrated oil from pumpkin seeds, and the fats it contains are what give it its potential health effects.
The capsule itself is made from gelatin, glycerin, and water, which are inactive ingredients that help deliver the oil.
Does it work?
Moderate evidence
The evidence for pumpkin seed oil is mixed. It's rated possibly effective for benign prostatic hyperplasia (BPH), the condition where an enlarged prostate causes urinary problems.
For other uses — androgenic alopecia (male pattern baldness), interstitial cystitis (bladder pain), parasitic infections, and urinary tract infections — the evidence isn't reliable enough to rate, so we can't say whether it works for those.
How safe is it?
Well-documented data
Pumpkin seed oil is generally well tolerated as a supplement in adults. The most common side effects seen in trials are mild — abdominal discomfort, diarrhea, nausea, and vomiting.
Anaphylaxis (a severe allergic reaction) is rare. There are also two case reports of transient hair loss after eating high-cucurbitacin pumpkin products (not typical ones), though this is uncommon.
Pregnancy and breastfeeding safety data isn't on file for this ingredient — talk to your doctor or pharmacist about whether it's right for you if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
If you take lithium, double-check with your pharmacist before starting this product — pumpkin seed oil may increase lithium levels (Moderate interaction). No other medication interactions are documented for the ingredients we could check.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Pumpkin seed oil may help with benign prostatic hyperplasia, and it's generally well tolerated. The main caution: if you take lithium, check with your pharmacist before starting — this supplement could raise your lithium levels.
For pregnancy or breastfeeding, get personalized advice from your doctor.
