HelloPharmacist Scorecard of Blueberry Leaf Powder 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.

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 powder. There are no inactive ingredients listed.

The blueberry is provided as a powder, which concentrates the compounds that give blueberries their potential health effects.

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 limited or lacking. For high blood pressure, the data we hold rates it as possibly ineffective.

For age-related cognitive decline, anxiety, athletic performance, high cholesterol, and heart disease, we don't have enough reliable evidence yet to say whether it works. If you're considering this for a specific health goal, talk with your doctor or pharmacist about what the current science actually shows.

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 generally well tolerated and widely eaten safely. This powder is generally well tolerated when taken by mouth, though some people experience constipation, diarrhea, nausea, or vomiting — especially with freeze-dried forms.

In one clinical trial, about a quarter of people taking 50 grams of freeze-dried blueberries daily quit in the first week due to stomach upset. For pregnancy, eating blueberries is fine, but concentrated supplements have not been well studied in pregnant people — there isn't enough data to know if high-dose powder is safe.

The same goes for breastfeeding: the safety of concentrated extracts while nursing is unknown. Talk with your doctor or pharmacist for personalized advice 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.

If you take blood sugar medications (antidiabetes drugs), be aware that blueberry powder may theoretically increase the risk of low blood sugar — check your exact medications and blood sugar levels closely. Also double-check if you take flurbiprofen for pain or buspirone for anxiety, since lab research shows blueberry may slow how your body clears these drugs.

Check your own medication Run your meds through the checker above

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 Powder may be worth trying if you're interested in blueberry's potential — the food itself is well tolerated and safe. However, if you take diabetes medications, pain relievers like flurbiprofen, or anxiety medications like buspirone, check with your own pharmacist or doctor first.

If you're pregnant or nursing, discuss it with your healthcare provider before starting.

Blueberry, Powder3 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 Leaf Powder by TerraVita Premium Collection: Common Questions

Does Blueberry Leaf Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Blueberry Leaf Powder 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 Powder 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 with blood pressure or high cholesterol?
For blood pressure, the evidence we have rates blueberry as possibly ineffective. For high cholesterol, we don't have enough reliable evidence yet to say whether it works. Talk with your doctor about proven treatments for these conditions.
Can I take this if I'm pregnant or breastfeeding?
Eating blueberries as food is fine during pregnancy and nursing. However, this is a concentrated supplement, and we don't have enough safety data on high-dose powders during pregnancy or breastfeeding. Talk with your doctor or pharmacist for personalized advice.
What side effects might I notice?
Most people tolerate blueberry powder well. Some experience constipation, diarrhea, nausea, or vomiting — stomach upset is the main concern. In one trial, about 26% of people taking a high dose quit in the first week due to digestive complaints.
Is this a food or a supplement?
This is blueberry in powder form — concentrated as a supplement, not a whole food. That's why the safety data is different from just eating fresh blueberries.
I take diabetes medication. Can I use this?
Animal research suggests blueberry may lower blood sugar, so combined with your medication it could theoretically increase the risk of low blood sugar. Check with your doctor or pharmacist before starting, and monitor your blood sugar closely if you do.
