HelloPharmacist Scorecard of Quince 450 mg by TerraVita Premium Collection

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

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: quince, a fruit used traditionally for digestive and respiratory support. The supplement also includes gelatin and water as inactive ingredients to form the capsule.

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 Quince's overall clinical evidence instead.

Moderate

Some clinical evidence supports Quince 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: Gastroesophageal reflux disease (GERD) — rated "Possibly Effective" (Natural Medicines).

Quince is rated possibly effective for GERD (acid reflux). For hay fever, asthma, pregnancy-related nausea and vomiting, and peptic ulcers, we don't have enough reliable evidence to say whether it works — the data we hold is insufficient to rate it either way.

The evidence, ingredient by ingredient Quince

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.

Quince as a food is generally well tolerated, but concentrated supplements haven't been well studied. Concentrated extracts or seed products in particular lack solid safety data, so it's wise to use caution.

We don't have enough reliable information on quince supplements during breastfeeding either, so if you're nursing, talk it over with your doctor or pharmacist before starting.

Side effects, ingredient by ingredient Quince

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 quince. That said, absence of documented interactions isn't a guarantee none exist, so it's still smart to run your medications through the checker on this page or confirm with your pharmacist.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. No medication interactions are currently documented, and some safety-information gaps remain.

Quince may help with acid reflux, though the evidence is moderate. If you're taking it for another reason — hay fever, asthma, or nausea in pregnancy — the evidence isn't there yet.

Because concentrated supplements aren't well studied, chat with your doctor or pharmacist before you start, especially if you're pregnant or breastfeeding.

Quince 450 mg by TerraVita Premium Collection: Common Questions

Does Quince 450 mg by TerraVita Premium Collection interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Quince 450 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Quince 450 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 quince really help with acid reflux?
Quince is rated possibly effective for GERD, which means there's some evidence behind it, but it's not a slam-dunk. If you're dealing with chronic acid reflux, it's worth discussing with your doctor to see if it fits into your plan.
Will this help my allergies or asthma?
We don't have enough reliable evidence to say. The data on quince for hay fever and asthma is insufficient, so we can't rate it either way.
Is it safe to take if I'm pregnant or breastfeeding?
There isn't enough reliable information on concentrated quince supplements during breastfeeding, so caution is advised and it's best to talk with your doctor or pharmacist first. For pregnancy, we don't have enough data to know either way — that's also a conversation to have with your healthcare provider.
What are the side effects?
We don't have adverse effects documented for quince in our data. That said, concentrated supplements haven't been well studied overall, so some people may experience mild digestive changes — if anything seems off, stop and check with your pharmacist.
Does this interact with my medications?
No interactions are documented in our data for quince. To be safe, run your exact medications through the checker on this page or confirm with your pharmacist — absence of documented interactions isn't a guarantee none exist.
