HelloPharmacist Scorecard of Pumpkin Powder by BulkSupplements.com

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 powder. Pumpkin is a seed and flesh extract traditionally used to support urinary and prostate health, though the strength of the evidence varies by use.

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

This product doesn't appear to be marketed for a specific use, so we graded Pumpkin's overall clinical evidence instead.

Moderate

Some clinical evidence supports Pumpkin for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Benign prostatic hyperplasia (BPH) — rated "Possibly Effective" (Natural Medicines).

The evidence for pumpkin is mixed. It's possibly effective for benign prostatic hyperplasia (BPH) — a common prostate enlargement in older men.

For other uses listed — including androgenic alopecia (pattern hair loss), interstitial cystitis (bladder pain), intestinal parasites, and urinary tract infections — there isn't enough reliable evidence yet to rate how well it works.

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 as a food is generally well tolerated. The most common side effects from pumpkin products are mild: abdominal discomfort, diarrhea, nausea, and vomiting.

Anaphylaxis (a severe allergic reaction) is rare. There are two case reports of temporary hair loss after eating bitter-tasting pumpkin or squash with high levels of a compound called cucurbitacin, which is found in wild pumpkins — though this is uncommon.

For pregnancy and breastfeeding, there isn't enough data on concentrated pumpkin supplements to know whether they're safe, so talk with your doctor or pharmacist before using one if you're pregnant or nursing.

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 for a mood disorder, double-check with your doctor or pharmacist before using pumpkin powder — it may increase your lithium levels and require a dose adjustment. No other medication interactions are documented in our data for this ingredient.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Pumpkin powder may help with prostate enlargement, though the evidence is strongest for that specific use. If you take lithium, you'll want to check with your doctor before starting, since pumpkin might raise your lithium levels.

For other uses, the science is still catching up. Talk it over with your own doctor or pharmacist before adding this to your routine.
