HelloPharmacist Scorecard of Bilberry 90 mg by BIOVEA

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.

Bilberry 90 mg is a single-ingredient supplement: bilberry extract. Each capsule delivers 90 mg of this fruit-derived ingredient, which is rich in compounds called anthocyanidins that give bilberries their deep blue color.

The capsule itself is made from inactive ingredients—rice flour, hydroxypropyl methylcellulose (a plant-based binder), microcrystalline cellulose, and vegetable magnesium stearate.

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 data on bilberry extract for its most common marketed use—night vision—shows it is possibly ineffective based on the evidence we hold. For other conditions bilberry is sometimes promoted for, such as age-related cognitive decline, age-related macular degeneration (AMD), atherosclerosis, high cholesterol (hyperlipidemia), and chronic venous insufficiency (CVI), the evidence is insufficient to rate its usefulness.

More research would be needed to know whether bilberry extract delivers real benefits for these conditions.

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 itself is generally well tolerated as a food, and orally, bilberry fruit, juice, and extracts appear to be generally well tolerated overall. However, the supplement evidence and long-term safety data are limited—most of what we know comes from food consumption rather than concentrated supplements.

The most common side effects are dark-colored stools, flatulence, and mild stomach discomfort. In one small study, about a third of participants taking concentrated bilberry juice reported mild-to-moderate gas, and some people have experienced temporary digestive upset.

Bilberry may also turn your stools and tongue dark blue or black; one person even had slight tooth discoloration. Because long-term safety data for supplement doses are lacking, use caution with concentrated bilberry supplements.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Bilberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 275 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 Bilberry 90 mg, check your medications against these types: blood thinners and antiplatelet drugs (warfarin, aspirin, clopidogrel)—bilberry may increase bleeding risk; diabetes drugs—bilberry may lower blood sugar further; drugs broken down by the CYP2E1 enzyme; and erlotinib (Tarceva), a cancer medication. All carry Moderate severity interactions.

Use the interaction checker on this page with your exact medication names, and confirm with your doctor or pharmacist.

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 extract is sometimes used for eye health and cognitive support, though the current evidence doesn't show it works for night vision. If you take blood thinners, diabetes medications, or certain cancer drugs, you'll need to check with your doctor or pharmacist before starting it—the interactions are real and could affect how well your medications work or increase your bleeding risk.

The supplement is generally well tolerated, though it may cause gas or temporarily darken your stools. Talk with your own healthcare provider about whether it fits your situation.

Bilberry 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 90 mg by BIOVEA: Common Questions

Does Bilberry 90 mg by BIOVEA interact with any medications?
Yes. Based on its ingredients, Bilberry 90 mg 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 90 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.
Does bilberry really help your eyesight?
The evidence says bilberry is possibly ineffective for night vision, which is its most common marketed use. For other eye and vision conditions like age-related macular degeneration, there isn't enough reliable evidence to say whether it works.
What are the most common side effects?
Dark-colored (blue or black) stools, gas, and mild stomach discomfort are the most common. In one study, about a third of people taking concentrated bilberry juice reported flatulence, and some had temporary digestive upset. Your tongue and even your teeth may also darken slightly.
Is bilberry safe to take while pregnant or breastfeeding?
Bilberry is rated likely safe during pregnancy and lactation. If you're pregnant or nursing, the available information does not advise against it, but talk with your doctor or pharmacist for advice tailored to your situation.
Is this supplement safe long-term?
Long-term safety data for concentrated bilberry supplements are limited. Most safety information comes from eating bilberry as a food rather than taking concentrated supplements, so caution is advised if you're planning to use it long-term.
Why does bilberry turn my stools dark?
Bilberry's natural blue-purple pigments (anthocyanidins) pass through your digestive system and color your stool and even your tongue dark blue or black. This is harmless but expected—it's just the pigment doing its normal job.
