HelloPharmacist Scorecard of Blueberry 450 mg 4:1 Extract 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 Jul 16, 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: blueberry extract in a 4:1 concentrate form (450 mg per capsule). The extract comes from the whole blueberry fruit and is delivered in a gelatin capsule with water as inactive ingredients.

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

This is a single-ingredient Blueberry product and its label doesn't state a use — see Blueberry's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for blueberry extract is mixed. It's rated possibly ineffective for high blood pressure.

For age-related memory decline, anxiety, athletic performance, and high cholesterol, the evidence we hold is insufficient to say whether it works. The data on cardiovascular disease benefit is also inconclusive.

The evidence, ingredient by ingredient Blueberry

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.

Blueberries eaten as food are generally well tolerated and widely consumed. This concentrated extract is generally well tolerated when taken orally, though freeze-dried blueberries have caused constipation, diarrhea, nausea, and vomiting in some people—in one trial, about a quarter of participants taking a high dose dropped out in the first week due to stomach complaints.

The safety data advises caution: concentrated blueberry supplements have not been well studied in pregnancy, and the safety of high-dose extracts during breastfeeding is unknown. Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant or nursing.

Side effects, ingredient by ingredient Blueberry

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Blueberry.
  • The most serious interaction on file is rated Minor.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 88 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.

Before taking this product, double-check with your doctor or pharmacist if you take antidiabetes medications (there's a Minor risk of low blood sugar), flurbiprofen (Ansaid), or buspirone (BuSpar). All three interactions are Minor severity, but your own healthcare provider can tell you whether any of them matter for your specific dose and health situation.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

Blueberry extract is generally well tolerated, but it can theoretically interact with antidiabetes drugs and a couple of other medications. If you take any prescription drugs—especially for diabetes, pain, or anxiety—check your specific medications with the tool on this page before starting.

Talk with your doctor or pharmacist to weigh whether the product makes sense for your situation.

Antidiabetes Drugs

Theoretically, blueberries or blueberry leaf extracts might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vitro research suggests that blueberry and/or blueberry leaf extracts can lower blood glucose levels.

Likelihood Unlikely Evidence D
Buspirone (Buspar)

Theoretically, blueberry juice might increase blood levels of buspirone.
In vitro research shows that blueberry juice can inhibit the metabolism of buspirone, possibly by inhibiting cytochrome P450 3A (CYP3A) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking buspirone hydrochloride 10 mg does not significantly affect the concentration or clearance of buspirone.

Likelihood Unlikely Evidence B
Flurbiprofen (Ansaid, Others)

Theoretically, blueberry juice might increase blood levels of flurbiprofen.
In vitro research shows that blueberry juice can inhibit the metabolism of flurbiprofen, possibly by inhibiting cytochrome P450 2C9 (CYP2C9) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking flurbiprofen 100 mg does not significantly affect the concentration or clearance of flurbiprofen.

Blueberry 450 mg 4:1 Extract by TerraVita Premium Collection: Common Questions

Does Blueberry 450 mg 4:1 Extract by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Blueberry 450 mg 4:1 Extract has a known interaction with 88 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Blueberry 450 mg 4:1 Extract 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.
Is blueberry extract safe to take while pregnant or breastfeeding?
The safety data advises caution. Eating blueberries as food is fine, but concentrated supplements like this one haven't been well studied in pregnancy, and the safety of high-dose extracts while breastfeeding is unknown. Talk with your doctor or pharmacist about what's right for you in your specific situation.
What side effects might I get from this product?
Blueberry extract is generally well tolerated. The most common side effects reported are constipation, diarrhea, nausea, and vomiting—mostly seen with high-dose freeze-dried forms. In one study, about a quarter of people taking a high daily dose stopped because of stomach problems in the first week.
Can blueberry extract help with my blood pressure or cholesterol?
The evidence doesn't support it for high blood pressure—it's rated possibly ineffective. For high cholesterol, the data we hold is insufficient to say whether it works or not.
I take diabetes medication. Is this supplement okay for me?
You need to check with your doctor or pharmacist first. Blueberry extract may theoretically increase the risk of low blood sugar when combined with antidiabetes drugs, since lab research suggests it can lower blood glucose on its own.
What's actually in this capsule?
One active ingredient: blueberry extract in a concentrated 4:1 form (450 mg). The capsule itself is made from gelatin and water.
