HelloPharmacist Scorecard of Pumpkin Seed Oil 2000 mg by tnvitamins

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 Oct 8, 2026

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 4 of its 4 active ingredients.
  • “Pumpkin seed Oil” is listed as a grouped ingredient — the label gives one combined amount (2,000 mg) without saying how much of each component you get.

This softgel lists four active ingredients: stearic acid, oleic acid, palmitic acid, and pumpkin seed oil, which is listed as a blend whose components are named individually. Oleic acid is the ingredient we hold the most detail on, and it is the one tied to our effectiveness and interaction notes.

The inactive ingredients are gelatin, glycerin, and purified water. These are non-active materials that help form and fill the softgel.

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 Oleic Acid's overall clinical evidence instead.

Moderate

Some clinical evidence supports Oleic Acid 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: Coronary heart disease (CHD) — rated "Possibly Effective" (Natural Medicines).
  • On file: Hypercholesterolemia — rated "Possibly Effective" (Natural Medicines).

Oleic acid carries the effectiveness ratings in our data. It is rated Possibly Effective for hypercholesterolemia (high cholesterol) and for coronary heart disease (CHD).

Possibly Effective means the evidence is promising but not firmly established. We hold no effectiveness ratings for stearic acid, palmitic acid, or linoleic acid.

The evidence, ingredient by ingredient Pumpkin Oleic Acid

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Oleic acid is generally well tolerated when consumed in food amounts, such as from olive oil. Our safety notes add that concentrated supplements are not well studied in pregnancy, and supplement-level doses lack good safety data overall.

No adverse effects are listed in our data for this product, but that is not a guarantee none occur. We hold no pregnancy or breastfeeding entry with a rating for oleic acid, and no such data is on file for stearic acid, palmitic acid, or linoleic acid.

If you are pregnant or breastfeeding, talk with your doctor or pharmacist for personalized advice.

Side effects, ingredient by ingredient Pumpkin Oleic Acid

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 — Oleic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

Double-check diabetes medications (antidiabetes drugs) before taking this product, since oleic acid might increase their effects with a Moderate severity rating. Our data holds no interaction information for stearic acid, palmitic acid, or linoleic acid, so those ingredients could not be checked.

Confirm your exact prescriptions with your own doctor or pharmacist.

The bottom line

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

This product may be worth discussing with your doctor if you are interested in the Possibly Effective evidence for oleic acid. If you take diabetes medications, be especially careful, since the documented interaction is Moderate.
