HelloPharmacist Scorecard of Standardized Bilberry Fruit Extract by Bluebonnet
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
This product contains one active ingredient: bilberry fruit extract, a concentrated form of the bilberry plant. Bilberry is a dark blue berry traditionally used to support eye and circulatory health.
The capsule itself is made from vegetable-derived materials, with cellulose, magnesium stearate, and silica as inactive ingredients to hold everything together.
Does it work?
Leans against
The evidence for bilberry extract is mixed and incomplete. For night vision, the data suggests it's possibly ineffective — meaning claims about sharp eyesight in low light don't hold up well in research.
For age-related cognitive decline, age-related macular degeneration (AMD), atherosclerosis, high cholesterol (hyperlipidemia), and chronic venous insufficiency, there simply isn't enough reliable evidence to say whether it works. If you're considering this supplement for any of these reasons, talk with your doctor or pharmacist about what the science actually supports.
How safe is it?
Well-documented data
Bilberry fruit as a food is generally well tolerated and safe. The supplement form, however, has limited long-term safety data, and we'd advise caution with concentrated doses.
The most common side effects you might notice are dark-colored stools (or even dark discoloration of your tongue or teeth), flatulence, and mild stomach discomfort. In small studies, a small number of people reported temporary digestive upset, and in one study roughly one-third of participants experienced mild-to-moderate gas — though that group had ulcerative colitis and lacked a control group, so the finding is limited.
Overall, when people do take it, bilberry extract seems to cause mostly tolerable effects.
Meds to double-check
Moderate interaction found
Before taking this product, check whether you take any blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel), diabetes medications, drugs metabolized by the CYP2E1 liver enzyme, or erlotinib. Bilberry extract may increase bleeding risk, lower your blood sugar further, or reduce how well these medications work.
The bottom line
Scorecard at a glanceFully disclosed formula with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you eat bilberries as food, that's fine. If you're thinking about taking this concentrated supplement, first check your medications against the interaction list below — especially if you take blood thinners, diabetes drugs, or cancer medications.
The evidence for what this supplement actually does is thin, and long-term safety data is limited. Talk with your pharmacist before starting.

Standardized Bilberry Fruit Extract by Bluebonnet Drug Interactions
HelloPharmacist Interaction Report
Bluebonnet's Standardized Bilberry Fruit Extract contains one active ingredient — bilberry fruit extract — which does interact with several medication types.
The most serious concern is with blood thinners and antiplatelet drugs (like warfarin, aspirin, or clopidogrel). Bilberry extract may slow down how your blood clots, raising the risk of bleeding if you're already on one of these medications.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to check if you take diabetes medications. Bilberry might lower your blood sugar further, which could tip you into low blood sugar (hypoglycemia).
Additionally, there are moderate interactions with drugs broken down by a liver enzyme called CYP2E1, and with erlotinib (a cancer drug). In both cases, bilberry extract might weaken how well these medications work.
Altogether, these interactions span 274 individual medications. We'd recommend running your exact medications through the interaction checker below before you start.

For each ingredient in Standardized Bilberry Fruit Extract with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Bilberry fruit extract
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.
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.
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.
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.
