HelloPharmacist Scorecard of Bilberry Berry Extract by Solgar
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 two active ingredients: standardized bilberry extract and blueberry powder. Bilberry extract is made from the fruit of the bilberry plant and has been concentrated to contain consistent levels of its active compounds.
Blueberry powder is simply dehydrated blueberry fruit in powder form. The product also contains a few inactive ingredients—microcrystalline cellulose and vegetable cellulose (both binders), vegetable magnesium stearate (a flow agent), and a proprietary PhytO2X blend—to form and deliver the capsules.
Does it work?
Couldn't assess
The evidence for bilberry extract's benefits is mixed and often limited. It is rated possibly ineffective for night vision, the claim it's most famous for.
For age-related cognitive decline, age-related macular degeneration, atherosclerosis, high cholesterol, and chronic venous insufficiency, there isn't enough reliable evidence to establish whether it works. Blueberry powder faces similar gaps.
It is rated possibly ineffective for high blood pressure and has insufficient evidence for cognitive decline, anxiety, athletic performance, high cholesterol, and cardiovascular disease.
How safe is it?
Well-documented data
Bilberry fruit as food is generally safe, and both bilberry extracts and blueberries are typically well tolerated when taken by mouth. However, the safety data on concentrated bilberry supplements, especially over the long term, is limited—so the caution here is that while food amounts are fine, high-dose extracts warrant care.
Most common side effects with bilberry include dark-colored or greenish stools, flatulence, and stomach discomfort; some people have also reported temporary tongue or tooth discoloration. Blueberry may cause constipation, diarrhea, nausea, or vomiting, particularly with freeze-dried forms—in one trial, stomach complaints were serious enough that a quarter of participants dropped out in the first week.
Both bilberry extract and blueberry powder are rated likely safe in pregnancy and lactation. However, the facts note that concentrated blueberry supplements haven't been well studied in pregnancy, and the safety of high-dose blueberry extracts while breastfeeding is unknown—talk it over with your doctor or pharmacist if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
If you take blood thinners or antiplatelet drugs (like warfarin, clopidogrel, or aspirin), diabetes medications, the cancer drug erlotinib, or drugs broken down by your liver's CYP2E1 or CYP3A enzymes, double-check your specific prescriptions with the interaction checker on this page before starting Solgar's Bilberry Berry Extract. The severity ranges from Moderate (bilberry with blood thinners and diabetes drugs) to Minor (blueberry with certain pain relievers and anxiety 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 and blueberry are familiar foods with long histories, and the extracts here are generally well tolerated. That said, the evidence that either one actually works for its popular claims—sharper night vision, clearer thinking, or better heart health—is thin to absent.
If you take blood thinners, diabetes medications, or other prescription drugs, check your exact medications with the tool on this page before starting. Then have a conversation with your doctor or pharmacist about whether this product makes sense for you and your health goals.

Bilberry Berry Extract by Solgar Drug Interactions
HelloPharmacist Interaction Report
Solgar's Bilberry Berry Extract contains two active ingredients—bilberry extract and blueberry powder—and there are documented interactions with medications.
The most serious concern is a Moderate-severity interaction between bilberry extract and blood thinners or antiplatelet drugs (like warfarin or aspirin): bilberry may increase bleeding risk by inhibiting platelet clumping, though this has been observed mainly in lab and animal studies, not yet in humans.
Read the full breakdown — every affected drug type, severity by severity
Bilberry extract also carries Moderate interactions with diabetes medications (a risk of low blood sugar), certain cancer drugs like erlotinib (Tarceva), and drugs broken down by the CYP2E1 liver enzyme. Blueberry powder adds Minor interactions with some diabetes medications, the pain reliever flurbiprofen, and the anxiety medication buspirone—all rooted in how your liver processes these drugs.
Altogether, these interactions span 277 individual medications. To know whether your specific prescriptions are affected, run them through the interaction checker on this page before you start.

For each ingredient in Bilberry Berry Extract with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
standardized Bilberry 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.
Blueberry powder
Antidiabetes Drugs
Theoretically, blueberries or blueberry leaf extracts might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vitro research suggests that blueberry and/or blueberry leaf extracts can lower blood glucose levels.
Buspirone (Buspar)
Theoretically, blueberry juice might increase blood levels of buspirone.
In vitro research shows that blueberry juice can inhibit the metabolism of buspirone, possibly by inhibiting cytochrome P450 3A (CYP3A) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking buspirone hydrochloride 10 mg does not significantly affect the concentration or clearance of buspirone.
Flurbiprofen (Ansaid, Others)
Theoretically, blueberry juice might increase blood levels of flurbiprofen.
In vitro research shows that blueberry juice can inhibit the metabolism of flurbiprofen, possibly by inhibiting cytochrome P450 2C9 (CYP2C9) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking flurbiprofen 100 mg does not significantly affect the concentration or clearance of flurbiprofen.
