HelloPharmacist Scorecard of Bilberry Fruit Mint 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.

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: bilberry fruit glycerite liquid extract. Bilberry is a small dark berry rich in anthocyanidins, natural compounds that give it antioxidant properties.

The glycerite form means the bilberry is extracted and suspended in glycerin, making it a liquid supplement with mint flavoring added.

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 Bilberry product and its label doesn't state a use — see Bilberry'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 what bilberry actually works for is thin. For night vision, the data suggests it's likely ineffective.

For age-related cognitive decline, age-related macular degeneration (AMD), atherosclerosis, high cholesterol (hyperlipidemia), and chronic venous insufficiency (poor circulation in the legs), there isn't enough reliable evidence in our data to rate how well it works. If you're considering it for any of these reasons, talk with your doctor about whether the evidence supports it for your situation.

The evidence, ingredient by ingredient Bilberry

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.

Bilberry fruit and juice from ordinary food amounts appear to be well tolerated. However, supplement doses—especially concentrated extracts like this one—have limited long-term safety data, and the research we hold advises caution with concentrated supplement doses.

The most common side effects are dark-colored stools, flatulence, and gastrointestinal discomfort. In trials, a small number of participants reported temporary GI upset, and some noticed dark or bluish discoloration of their stools and tongue—a harmless cosmetic effect from the berry's natural pigments.

Bilberry is rated Likely Safe in pregnancy and lactation, so food amounts would not be expected to cause problems, but long-term supplement safety in these situations hasn't been well studied.

  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Bilberry Fruit Mint Flavor might appeal to you if you're looking for a traditional herbal supplement, but the evidence that it actually works for vision, cognition, or circulation is either weak or missing from our data. More importantly, if you take blood thinners, diabetes drugs, certain cancer medications, or drugs processed by a liver enzyme (CYP2E1), this product could interfere with them.

Talk with your doctor or pharmacist before starting it, especially if you're on any prescriptions.

Bilberry Fruit Glycerite Liquid Extract4 drug types · 275 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, bilberry fruit extract might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro, animal, and clinical research suggest that anthocyanidin extracts from bilberry can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, bilberry leaf or fruit extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that bilberry leaf extract might have blood glucose-lowering activity. Also, one small clinical trial in patients with type 2 diabetes shows that taking bilberry fruit extract 470 mg as a single dose prior to an oral glucose tolerance test lowers plasma glucose levels when compared with placebo.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, bilberry fruit extract might decrease levels of drugs metabolized by CYP2E1.
Animal research shows that exposure to small concentrations of bilberry extract in drinking water for around one month increased CYP2E1 activity by 31%. However, exposure over a 2-month period did not increase CYP2E1 activity. This effect has not been reported in humans.

Likelihood Possible Evidence D
Erlotinib (Tarceva)

Theoretically, bilberry fruit extract might reduce the efficacy of erlotinib.
In vitro research suggests that bilberry fruit extract and its constituents, delphinidin and delphinidin-3-O-glucoside, inhibit the activity of erlotinib. This interaction has not been reported in humans.

Bilberry Fruit Mint Flavor by TerraVita: Common Questions

Does Bilberry Fruit Mint Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Bilberry Fruit Mint Flavor has a known interaction with 275 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bilberry Fruit Mint Flavor 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.
Does bilberry actually help night vision?
No—the evidence suggests it's likely ineffective for that. This is one of the most popular claims about bilberry, but the science doesn't back it up.
What are the side effects I might notice?
The most common ones are dark-colored stools, gas, and mild stomach discomfort. You may also see a dark or bluish tint to your stools and tongue—that's just the berry's natural pigment and isn't harmful.
Is it safe to take bilberry while pregnant or nursing?
Bilberry from food is rated Likely Safe during pregnancy and lactation, so ordinary amounts shouldn't be a problem. Long-term safety data on supplement doses, though, hasn't been well studied in these situations—talk with your doctor or pharmacist if you're pregnant or nursing and want to take this.
What's the difference between this liquid extract and whole bilberry?
This is a glycerite—the bilberry has been extracted and concentrated into a liquid form for easier dosing. Whole berries or juice from food are likely fine, but concentrated supplement extracts like this one have limited long-term safety data.
Will bilberry lower my blood sugar if I'm diabetic?
Possibly—animal studies suggest bilberry can lower blood glucose, so if you're already taking diabetes medication, combining them could increase the risk of low blood sugar. Talk with your doctor or pharmacist before adding this product.
