HelloPharmacist Scorecard of Bilberry 160 mg by Solaray

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.

From our pharmacy team — supplement deep dive

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 2 of its 2 active ingredients.
  • “Bilberry Extract” is listed as a grouped ingredient — the label gives one combined amount (160 mg) without saying how much of each component you get.

This product has two active ingredients. Bilberry extract and blueberry extract are both plant concentrates — the bilberry extract is a blend of its component parts listed separately here.

The main active compounds you're getting are anthocyanosides, a type of plant pigment in these berries. The capsule also contains inactive ingredients: cellulose, magnesium stearate, and a rice extract blend.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Blueberry's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Circulation and eye support.
  • We looked for evidence on: Age-related macular degeneration (AMD), Asthenopia (eye strain), Atherosclerosis, Cardiovascular disease (CVD), Cataracts, Chronic venous insufficiency (CVI) — and 4 related terms.
  • The closest evidence on file: Blueberry is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD) (Natural Medicines).
  • Also on file: Blueberry is rated "Insufficient Reliable Evidence To Rate" for Cataracts.

The evidence for blueberry extract is mixed and often thin. For high blood pressure (hypertension), the data suggests it's likely ineffective.

For age-related memory loss, anxiety, athletic performance, and high cholesterol, we don't have enough reliable evidence to say whether it works or doesn't. The facts we hold don't establish that this product is effective for any condition.

The evidence, ingredient by ingredient Bilberry Blueberry

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.

Blueberries themselves are eaten safely by millions of people, and the extract is generally well tolerated. The most common side effects in trials were gastrointestinal — constipation, diarrhea, nausea, and vomiting, especially with freeze-dried blueberries at high doses.

In one study, over a quarter of people taking 50 grams daily of freeze-dried blueberries quit within the first week due to stomach upset. For pregnancy and breastfeeding: while eating blueberries as food is fine, concentrated supplements haven't been well studied in pregnancy or during breastfeeding.

Talk with your doctor or pharmacist before taking this if you're pregnant or nursing.

Side effects, ingredient by ingredient Bilberry Blueberry

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Blueberry.
  • The most serious interaction on file is rated Minor.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 88 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.

Check before taking this if you use antidiabetes drugs — blueberry extract may increase the risk of low blood sugar. Also double-check if you take flurbiprofen (an anti-inflammatory) or buspirone (an anxiety medication), though these interactions are minor.

No interactions are documented for anthocyanosides.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Only minor medication interactions are documented, and safety information is well characterized.

This product is a blueberry concentrate that some people try for circulation or eye health, though the evidence is limited. If you take antidiabetes medications, blood thinners, or anxiety drugs, check with your pharmacist first — blueberry can affect how your body handles these.

Generally well tolerated, but stomach upset is possible at higher doses.

For each ingredient in Bilberry 160 mg 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.

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.

Likelihood Possible Evidence D
Bilberry Extract full monograph & interactions

Blueberry Extract3 drug types · 88 drugs

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.

Likelihood Unlikely Evidence D
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.

Likelihood Unlikely Evidence B
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.

Bilberry 160 mg by Solaray: Common Questions

Does Bilberry 160 mg by Solaray interact with any medications?
Yes. Based on its ingredients, Bilberry 160 mg has a known interaction with 277 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bilberry 160 mg contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough data to know whether concentrated blueberry supplements are safe in pregnancy or while breastfeeding, even though eating fresh blueberries is fine. Talk with your doctor or pharmacist about whether this product is right for you.
What side effects might I notice?
Most people tolerate it well. The most common side effects are gastrointestinal — constipation, diarrhea, nausea, or vomiting. In one trial, over a quarter of people taking a high dose quit within the first week due to stomach problems.
Does blueberry extract actually work for anything?
The evidence we hold shows blueberry is likely ineffective for high blood pressure. For memory, anxiety, athletic performance, and cholesterol, we don't have enough reliable evidence to say whether it works.
Why can't you check anthocyanosides for interactions?
We hold no interaction data for anthocyanosides, so we can't tell you whether it interacts with medications. That doesn't mean interactions don't exist — just that we don't have that information on file.
Is this safe to take with my diabetes or anxiety medication?
Blueberry extract may theoretically increase the risk of low blood sugar with diabetes drugs and may raise levels of buspirone (an anxiety medication). Both are minor interactions, but check with your pharmacist using the tool on this page with your exact medication names.
