HelloPharmacist Scorecard of Blueberry Leaf Vanilla Flavor by TerraVita

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.

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 glycerite liquid extract. That's a concentrated form of blueberry leaf made by soaking the plant material in glycerin, which draws out the active compounds.

The other ingredients — glycerin and vanilla flavor — are inactive additives that provide the carrier liquid and taste. There's no filler list beyond those.

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 on blueberry leaf for most uses is thin. For high blood pressure (hypertension), it's rated possibly ineffective.

For age-related cognitive decline, anxiety, athletic performance, high cholesterol (hyperlipidemia), and heart disease, we don't have enough reliable evidence to rate whether it works. If you're considering this for one of those reasons, talk it over with your doctor — the science isn't there yet to say it'll help.

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 themselves are eaten as food all the time and are generally well tolerated. This concentrated extract, though, hasn't been well studied in pregnancy — the safety data advises caution, so talk with your doctor or pharmacist for personalized advice if you're pregnant or planning to be.

For breastfeeding, we don't have enough information on high-dose extracts. Some people on freeze-dried blueberries have reported constipation, diarrhea, nausea, and vomiting — in one trial, a quarter of participants dropped out in the first week due to stomach upset.

This liquid extract may carry similar risks.

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.

Check with your doctor or pharmacist before taking this product if you're on antidiabetes medication — there's a Minor risk that blueberry leaf might lower your blood sugar too much. You should also double-check if you take flurbiprofen (Ansaid) or buspirone (BuSpar), as this product may increase their blood levels.

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 worth considering if you're looking for a traditional approach to wellness, but the evidence for most uses is weak. If you take antidiabetes medication, flurbiprofen, or buspirone, you'll want to check with your doctor or pharmacist first.

Blueberry Leaf Glycerite Liquid 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.
