HelloPharmacist Scorecard of Pumpkin Seed Oil 1000 mg by GNC
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 2 active ingredients: pumpkin seed oil and polyunsaturated fat. Pumpkin seed oil is the star here — it's a concentrated extract from pumpkin seeds that's been studied for prostate and urinary health.
The capsule itself is made from gelatin and glycerin, which are inactive ingredients that hold everything together.
Does it work?
Moderate evidence
Pumpkin seed oil has possibly effective evidence for benign prostatic hyperplasia (BPH) — that's the noncancerous swelling of the prostate that can happen as men age. For other uses listed on the label — androgenic alopecia (male-pattern hair loss), interstitial cystitis (chronic bladder pain), parasite infections, and urinary tract infections — the evidence we have is insufficient to rate it.
That doesn't mean it doesn't work for those; it means the studies aren't solid enough yet to say.
How safe is it?
Well-documented data
Pumpkin seed oil is generally well tolerated when taken as a supplement. The most common side effects reported in trials were mild — abdominal discomfort, diarrhea, nausea, and vomiting — and rare cases of anaphylaxis (a severe allergic reaction) have been reported, though this is uncommon.
Eating pumpkin as food is safe, but there isn't enough safety data on concentrated seed supplements during pregnancy and breastfeeding to know either way; talk with your doctor or pharmacist before using this product if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Lithium (Moderate severity): pumpkin seed oil may reduce how your body clears it, raising levels in your blood. Check with your doctor or pharmacist before starting this product if you take lithium.
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.
GNC Pumpkin Seed Oil may be worth trying if you're dealing with prostate swelling and want a supplement with some evidence behind it. If you take lithium, check with your doctor or pharmacist before starting — you may need a dose adjustment.
Otherwise, run your medications through the checker on this page to be sure, and talk it over with your healthcare provider if you have questions.

HelloPharmacist Interaction Report
GNC Pumpkin Seed Oil 1000 mg interacts with one medication type through its pumpkin seed oil content.
The main concern is lithium, a mood-stabilizing medication: pumpkin seed oil is thought to have diuretic properties (it increases urine output), which may reduce how your body clears lithium and cause levels to build up in your bloodstream.
