HelloPharmacist Scorecard of Blueberry Extract by DC

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, a concentrate of the compound found in fresh blueberries. The softgel capsule also contains several inactive ingredients used as binders and capsule materials — gelatin, soybean oil, glycerin, soy lecithin, yellow beeswax, and natural caramel color.

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: antioxidant support to neutralize free radicals.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for blueberry extract's effectiveness is mixed and incomplete. For hypertension (high blood pressure), the data shows it's possibly ineffective.

For age-related cognitive decline, anxiety, athletic performance, hyperlipidemia (high cholesterol), and cardiovascular disease, there isn't enough reliable evidence yet to say whether it works. You're not looking at a supplement with a strong track record for any specific condition in the data we hold.

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.

Blueberry extract is generally well tolerated when taken by mouth. The most common side effects reported in trials are constipation, diarrhea, nausea, and vomiting — especially with freeze-dried forms.

In one clinical trial, about one in four people taking 50 grams daily of freeze-dried blueberries stopped the study in the first week due to stomach and bowel complaints, so gastrointestinal upset can be significant for some. For pregnancy, concentrated extracts haven't been well studied — the safety data you'd want isn't there.

The same goes for breastfeeding: high-dose extract safety is unknown. Fresh blueberries as food are fine, but this supplement is a concentrated form.

Talk with your doctor or pharmacist about whether it's right for you during pregnancy or while nursing.

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 you take DC Blueberry Extract, double-check if you're on antidiabetes drugs — this extract may lower your blood sugar further. Also confirm your dose if you're taking flurbiprofen (Ansaid) or buspirone (BuSpar), as the extract may raise their blood levels.

Use the search tool on this page to verify your exact medications.

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.

If you take antidiabetes medications, anti-anxiety drugs like buspirone, or nonsteroidal anti-inflammatories like flurbiprofen, you'll want to check your specific medications before starting this product. Blueberry extract is generally well tolerated, though digestive upset can happen.

The evidence for what it actually does for most conditions is thin. Have a conversation with your doctor or pharmacist about whether this fits your needs.

Blueberry Extract3 drug types · 88 drugs

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 Extract by DC: Common Questions

Does Blueberry Extract by DC interact with any medications?
Yes. Based on its ingredients, Blueberry 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 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.
Can I take this if I'm pregnant?
The safety data for high-dose concentrated extracts during pregnancy isn't established — we don't have enough information to know either way. Fresh blueberries as food are fine, but this is a concentrated supplement. Talk with your doctor or pharmacist for personalized advice.
Is it safe while breastfeeding?
The safety of high-dose blueberry extract while breastfeeding is unknown. Fresh blueberries as food are fine, but concentrated supplements haven't been studied enough. Check with your doctor or pharmacist about what's right for you.
What side effects might I notice?
Most people tolerate it well, but constipation, diarrhea, nausea, and vomiting can happen — especially with freeze-dried forms. In one trial, about one in four people taking 50 grams daily stopped early because of stomach and bowel problems in the first week.
Does it actually work for blood pressure or cholesterol?
For hypertension, the data shows it's likely not effective. For high cholesterol and heart disease, there isn't enough reliable evidence yet to say whether it helps. This isn't a supplement with proven results for those conditions in the research we hold.
What's the difference between this supplement and eating fresh blueberries?
This is a concentrated extract, so you're getting a more potent dose than you'd eat as whole fruit. The safety profile for high-dose extracts hasn't been studied as thoroughly as eating blueberries as food, which is why pregnancy and breastfeeding safety are uncertain for the supplement.
