HelloPharmacist Scorecard of Bilberry Extract by BulkSupplements.com
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 a single active ingredient: bilberry fruit extract. Bilberry has a long history as both a food and a traditional remedy, and the extract concentrates compounds called anthocyanidins that give bilberries their deep color.
There are no other inactive ingredients listed in this powder.
Does it work?
Couldn't assess
The evidence for bilberry extract is mixed and often limited. For night vision, the data suggests it's likely ineffective — despite the popular belief.
For age-related cognitive decline, age-related macular degeneration, atherosclerosis, high cholesterol, and chronic venous insufficiency, there simply isn't enough reliable evidence yet to say whether it works. If you're considering bilberry for one of these uses, talk with your doctor about whether the current evidence supports trying it.
How safe is it?
Well-documented data
Bilberry fruit itself is generally well tolerated as a food. However, the safety data for concentrated supplements is limited, and the manufacturers advise caution with supplement doses due to lack of long-term safety data.
Common side effects from bilberry extracts are mostly mild and involve your digestive tract — dark-colored or black stools, gas, and stomach discomfort. In studies, these happened in a minority of people.
Some folks also report temporary darkening of the tongue or teeth. If you're pregnant or breastfeeding, bilberry is rated as likely safe, but talk with your doctor or pharmacist before starting any supplement.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking this if you use blood thinners or antiplatelet drugs (like warfarin or aspirin) — bilberry may increase bleeding risk. Do the same if you take diabetes medications, since bilberry may lower blood sugar further.
Also flag it if you're on erlotinib (Tarceva) or other drugs metabolized by the liver enzyme CYP2E1, as bilberry may reduce their effectiveness.
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 may appeal to you if you're interested in traditional eye health support, but the evidence for its effectiveness is weak or absent for most claims. The bigger issue is that it can interact with blood thinners, diabetes medications, and certain cancer drugs — so if you take any prescription medications, check them against this product before you start.
Talk it over with your doctor or pharmacist to make sure it's right for your situation.

HelloPharmacist Interaction Report
Bilberry Extract by BulkSupplements.com does interact with several types of medications, and the most serious concern involves blood thinners.
Bilberry fruit extract may increase your bleeding risk if you're taking anticoagulants or antiplatelet drugs like warfarin or aspirin — research suggests the active compounds in bilberry can slow how your blood clots.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to check if you take diabetes medications. Bilberry extract may lower blood sugar further, raising the risk of low blood sugar (hypoglycemia).
Additionally, it may affect how your body processes certain cancer drugs, particularly erlotinib (Tarceva), by potentially reducing their effectiveness. There's also a theoretical concern with medications broken down by a liver enzyme called CYP2E1, though the research here is mixed.
Additionally, no interactions are documented in our data for any other drug categories. Altogether, these interactions span 275 individual medications.
Before you start this supplement, run your exact prescriptions through the interaction checker below, or talk with your doctor or pharmacist about whether it's safe to combine with what you're taking.

For each ingredient in Bilberry 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.
