HelloPharmacist Scorecard of Pumpkin Seed by Mountain Meadow Herbs

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 10, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Pumpkin seed extract” is listed as a grouped ingredient — the label gives one combined amount (1.25 mL) without saying how much of each component you get.

This product contains 3 active ingredients: vegetable glycerin, distilled water, pumpkin seed extract, and organic grain alcohol. Vegetable glycerin is a sweet compound often used as a sweetener and humectant (moisture-retaining agent) in supplements.

Pumpkin seed extract is the main active component here, though the product facts do not specify which compounds within it are responsible for its effects. The alcohol serves as a preservative in the liquid formulation.

Does it work?

Couldn't assess
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
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Prostate and bladder health support.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Overactive bladder, Urinary symptoms, Prostate function.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence we hold covers only vegetable glycerin, one of the three ingredients. Glycerin is likely effective for constipation and possibly effective for athletic performance.

For ichthyosis (a dry skin condition), it's possibly effective. Against meningitis and stroke, the evidence rates it likely ineffective or possibly ineffective.

We have no effectiveness data on file for pumpkin seed extract itself.

The evidence, ingredient by ingredient Pumpkin Glycerol

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.

Vegetable glycerin is generally well tolerated in typical amounts, though large oral doses can cause stomach upset, bloating, nausea, vomiting, diarrhea, dizziness, headache, and increased thirst. Topical use and food-level intake appear safe, but talk with your doctor before using medicinal doses.

We hold little specific safety data for the other ingredients in this product. Before starting a larger or medicinal dose, check with your doctor.

Side effects, ingredient by ingredient Pumpkin Glycerol

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredients we could check. However, we hold no interaction data for distilled water or organic grain alcohol, so check your exact medications with the search tool on this page before starting.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.

Mountain Meadow Herbs Pumpkin Seed Liquid may interest anyone looking for pumpkin seed support, though we cannot speak to how well the extract works from the data we hold. Because we couldn't check distilled water and grain alcohol for interactions, and because glycerin at high doses can upset your stomach, talk with your doctor or pharmacist before adding this to your routine, especially if you take medications or have a sensitive gut.
