HelloPharmacist Scorecard of Bilberry Extract 25% Anthocyanidin by Herb Xtra
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
Partial disclosure
This product contains 4 ingredients total. The active ingredient is 20 mg of bilberry extract concentrated to a 100:1 ratio — that means it's a concentrated form that delivers the anthocyanidins (the blue pigments) bilberries are known for.
The other three ingredients are gelatin (the capsule itself), water, and 230 mg of cellulose fiber, which are inactive — they're there to hold the capsule together and help it dissolve.
Does it work?
Leans against
The evidence for bilberry extract is limited. For night vision, the data rates it as possibly ineffective — meaning the studies we have don't support that claim.
For other uses like age-related macular degeneration, cognitive decline, atherosclerosis, high cholesterol, and chronic venous insufficiency, we don't have enough reliable evidence in our data to rate how well it works. If you're considering this for a specific condition, talk to your pharmacist about what the current research actually shows.
How safe is it?
Well-documented data
Bilberry extract is generally well tolerated when taken by mouth. The most common side effects are mild: dark-colored stools (from the pigments), flatulence, and mild stomach discomfort.
A small number of trial participants reported these effects. Gelatin, the capsule material, is safe in food amounts, though you should check with your doctor about supplement doses.
Some people can have allergic reactions to gelatin, though that's rare. There's limited long-term safety data for bilberry extract supplements specifically, so the data advises caution with concentrated forms.
Meds to double-check
Moderate interaction found
Before you take this, double-check if you're on blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel) — bilberry may increase bleeding risk. Also check diabetes medications (metformin, insulin, sulfonylureas) because bilberry may lower blood sugar further.
If you take erlotinib (Tarceva) or drugs metabolized by CYP2E1, flag those too.
The bottom line
Scorecard at a glancePartially disclosed formula with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product is generally well tolerated and has a straightforward safety profile for most people. But because of the interactions with blood thinners, diabetes drugs, and certain other medications, you really do need to check your prescriptions before starting it.
If you're on any regular medication, run it through the tool below first — and talk to your pharmacist.

Bilberry Extract 25% Anthocyanidin by Herb Xtra Drug Interactions
HelloPharmacist Interaction Report
Herb Xtra's Bilberry Extract 25% Anthocyanidin does interact with several medication types, so it's worth a quick check before you start.
The most serious concern is with blood thinners and antiplatelet drugs (like warfarin, aspirin, and clopidogrel) — bilberry extract may increase bleeding risk by interfering with how your platelets clump together. This is a Moderate-severity interaction.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to watch for interactions with diabetes medications. Bilberry extract may lower blood sugar (hypoglycemia) on its own, so combining it with drugs like metformin, sulfonylureas, or insulin could push your levels too low.
That's also Moderate severity. Additionally, bilberry extract may speed up how your liver breaks down certain drugs processed through the CYP2E1 enzyme pathway — which could make them less effective — and it may reduce how well erlotinib (Tarceva), a cancer drug, works.
Both are Moderate interactions.
We couldn't check water or cellulose fiber for interactions. Altogether, these interactions span 274 individual medications.

For each ingredient in Bilberry Extract 25% Anthocyanidin 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.
20 mg Bilberry Extract 100:1
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.
