HelloPharmacist Scorecard of Blueberry Leaf Extract 60 mg by Swanson Superior 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

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 leaf extract at 60 mg per capsule. The extract comes from the leaves of the blueberry plant and delivers compounds that research suggests may affect blood sugar and how certain medications are processed in your body.

The capsule also contains inactive ingredients — rice bran, gelatin, silica, magnesium stearate, and maltodextrin — that serve as fillers and binders.

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 leaf extract is mixed. For high blood pressure (hypertension), it's rated possibly ineffective — meaning the data we hold does not support a benefit.

For age-related cognitive decline, anxiety, athletic performance, high cholesterol (hyperlipidemia), and heart disease, there isn't enough reliable evidence in our data to rate how well it works. If you're considering this supplement for any of these reasons, talk with your doctor or pharmacist about what the current evidence actually shows for your specific situation.

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 as food are well tolerated and eaten widely. This concentrated supplement, however, hasn't been studied much in pregnancy or while breastfeeding — the safety data simply isn't there.

If you're pregnant or nursing and considering this extract, check with your doctor or pharmacist. Common side effects from freeze-dried blueberries in studies include constipation, diarrhea, nausea, and vomiting; one trial found that 26% of people taking 50 grams daily stopped within the first week due to stomach upset.

This product is 60 mg — a much smaller dose — but digestive effects remain possible.

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, check with your doctor or pharmacist if you take any blood sugar medication (the most important), flurbiprofen or other NSAIDs, or buspirone. These are the medication types documented to interact with blueberry leaf extract in our data.

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 leaf extract is generally well tolerated, but it may lower blood sugar and could slow how your body clears certain medications. If you take diabetes drugs, flurbiprofen, or buspirone, check your exact medications with your doctor or pharmacist before starting.

The evidence for heart, cholesterol, brain, or anxiety benefits isn't solid, so be clear on why you're taking it.

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 Leaf Extract 60 mg by Swanson Superior Herbs: Common Questions

Does Blueberry Leaf Extract 60 mg by Swanson Superior Herbs interact with any medications?
Yes. Based on its ingredients, Blueberry Leaf Extract 60 mg 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 Leaf Extract 60 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.
Will this help my blood sugar or blood pressure?
For blood pressure, the evidence doesn't support a benefit. For blood sugar, while blueberry extract may lower it in lab studies, that's also why it could interact with diabetes drugs — and we don't have solid evidence it helps manage diabetes itself. Talk with your doctor about what you're trying to treat and whether this supplement fits your plan.
Is it safe to take while pregnant or breastfeeding?
Eating blueberries is fine, but concentrated supplements like this haven't been well studied in pregnancy or while nursing. The safety data just isn't there. If you're pregnant or breastfeeding and want to take this, check with your doctor or pharmacist first.
What are the side effects?
Blueberry extract is generally well tolerated, but freeze-dried blueberries have caused constipation, diarrhea, nausea, and vomiting in studies — sometimes enough that people stopped taking them. This product is a smaller dose, but digestive upset remains possible.
Can I take this with my blood pressure or diabetes medication?
If you take diabetes drugs, there's a theoretical risk of blood sugar dropping too low when combined with blueberry extract. For blood pressure medication, the interaction data we have doesn't flag a concern — but run your exact medication list through the checker on this page to be sure.
What is blueberry leaf extract made from?
It's a concentrated extract from blueberry plant leaves, delivered at 60 mg per capsule. The capsule itself is made with gelatin, rice bran, silica, magnesium stearate, and maltodextrin.
