HelloPharmacist Scorecard of Pumpkin Seed Oil 1,000 mg by Wonder Laboratories

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
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: pumpkin seed oil at 1,000 mg per softgel. The oil is delivered in gelatin and vegetable glycerin capsules.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: pumpkin seed oil nutrient supplement.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Overactive bladder, prostate health, urinary function.
  • The strongest evidence on file: Pumpkin is rated "Possibly Effective" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Pumpkin is rated "Insufficient Reliable Evidence To Rate" for Overactive bladder.

The evidence supporting pumpkin seed oil is mixed. It's rated possibly effective for benign prostatic hyperplasia (BPH)—enlarged prostate—based on available research.

For hair loss (androgenic alopecia), urinary tract infections, interstitial cystitis (bladder pain), and parasitic infections, the evidence we hold is too thin to rate it either way. If you're considering it for one of those other uses, talk with your doctor about what the current research shows.

The evidence, ingredient by ingredient Pumpkin

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Pumpkin seed oil is generally well tolerated as an oral supplement in adults. The most common side effects in trials are mild: abdominal discomfort, diarrhea, nausea, and vomiting.

Anaphylaxis (a severe allergic reaction) is extremely rare. Two case reports describe hair loss occurring 1–3 weeks after eating bitter-tasting pumpkin or squash with high levels of cucurbitacin (a naturally occurring plant compound), though this is uncommon.

There is not enough safety data on concentrated seed-oil supplements during pregnancy or breastfeeding, so it's best to talk with your doctor before taking it in those situations.

Side effects, ingredient by ingredient Pumpkin

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Pumpkin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 1 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take lithium, do not start this product without confirming with your doctor or pharmacist first—pumpkin seed oil may reduce how quickly your body clears it, raising lithium levels. No other medications are documented to interact with pumpkin seed oil in our data.

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 enlarged prostate symptoms, though the evidence is strongest for that use. If you take lithium, check with your doctor before starting this supplement—it may affect how your body processes the medication.

Pumpkin Seed Oil 1,000 mg by Wonder Laboratories: Common Questions

Does Pumpkin Seed Oil 1,000 mg by Wonder Laboratories interact with any medications?
Yes. Based on its ingredients, Pumpkin Seed Oil 1,000 mg has a known interaction with 1 medication. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pumpkin Seed Oil 1,000 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does pumpkin seed oil actually help with prostate problems?
It's rated possibly effective for benign prostatic hyperplasia (BPH), or enlarged prostate. That means there's some evidence supporting it, though more research would help us be more certain. Talk with your doctor about whether it's right for your situation.
What are the most common side effects?
Abdominal discomfort, diarrhea, nausea, and vomiting are the most common ones reported in trials. Most people tolerate it well, and serious reactions are very rare.
Can I take this if I'm pregnant or breastfeeding?
We don't have enough safety data on concentrated seed-oil supplements during pregnancy or breastfeeding. Talk with your doctor about whether it's okay for your situation.
Is this product just a filler, or does it actually have active ingredient?
It's one active ingredient: 1,000 mg of pumpkin seed oil per capsule. The gelatin and glycerin are just the capsule material to hold it.
I heard pumpkin can cause hair loss. Should I be worried?
There are two rare case reports of temporary hair loss after eating bitter-tasting pumpkin or squash with unusually high levels of a plant compound called cucurbitacin—which is not typical of the pumpkin seed oil in this supplement. It's very uncommon.
