HelloPharmacist Scorecard of Bilberry Plus 6000 mg by SimplySupplements

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Bilberry Plus 6000 mg contains one active ingredient: bilberry extract, a concentrate from bilberry fruit. The tablet also contains microcrystalline cellulose, magnesium stearate, and silicon dioxide as inactive ingredients (binders and flow agents that help hold the tablet together).

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 Bilberry's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: antioxidant support for eyes and body health.
  • We looked for evidence on: Age-related macular degeneration (AMD), Asthenopia (eye strain), Cataracts, Chronic venous insufficiency (CVI), Diabetic retinopathy, Dry eye — and 4 related terms.
  • The closest evidence on file: Bilberry is rated "Possibly Ineffective" for Night vision (Natural Medicines).
  • Also on file: Bilberry is rated "Insufficient Reliable Evidence To Rate" for Age-related macular degeneration (AMD), Cataracts, Chronic venous insufficiency (CVI), Diabetic retinopathy, and more.

The evidence for bilberry extract is mixed and often limited. For night vision, the data suggests it's possibly ineffective.

For age-related cognitive decline, age-related macular degeneration, atherosclerosis, high cholesterol, and chronic venous insufficiency (poor circulation in the legs), we don't have enough reliable evidence to say whether it works. The facts we hold don't establish a clear benefit for any of these conditions.

The evidence, ingredient by ingredient Bilberry

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.

Bilberry fruit in food amounts is generally well tolerated, but the safety data for concentrated supplements is sparse and long-term safety isn't well studied. The safety notes advise caution — supplement doses are used without enough reliable safety information.

The most common side effects from bilberry are dark-colored stools, flatulence, and mild stomach discomfort. In some trials, around a third of participants reported mild-to-moderate gas, and temporary stomach upset occurred in a smaller number.

You may also notice dark discoloration of your stools, tongue, or even teeth — this is harmless staining from the extract's natural color.

Side effects, ingredient by ingredient Bilberry

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Bilberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 275 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.

Before taking Bilberry Plus, check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like warfarin, clopidogrel, or aspirin) — bilberry may increase bleeding risk. Also double-check if you take diabetes medications, since bilberry may lower blood sugar further.

If you're on erlotinib (a cancer drug) or any medication metabolized by the liver enzyme CYP2E1, mention this product too.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Bilberry extract is not well proven for any of the conditions it's marketed for, and concentrated supplement forms lack solid long-term safety data. If you take blood thinners, diabetes medications, or erlotinib, this product is worth discussing with your doctor or pharmacist first.

For most others, the main caution is limited evidence of benefit and the lack of robust safety testing in supplement form.

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.

Bilberry Plus 6000 mg by SimplySupplements: Common Questions

Does Bilberry Plus 6000 mg by SimplySupplements interact with any medications?
Yes. Based on its ingredients, Bilberry Plus 6000 mg has a known interaction with 275 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bilberry Plus 6000 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Does bilberry really help with eyesight or night vision?
For night vision, the evidence suggests it's not effective. For other eye conditions like age-related macular degeneration, we don't have enough reliable data to know if it works. The hype around bilberry and vision is stronger than what the research actually shows.
Is bilberry safe to take while I'm pregnant or breastfeeding?
Bilberry is rated as likely safe in pregnancy and lactation. That said, the safety data on concentrated supplements is limited, so it's worth talking to your doctor or midwife before starting.
What are the side effects?
Bilberry is generally well tolerated. The most common side effects are dark stools, gas, and mild stomach discomfort. You may also notice dark staining of your tongue, teeth, or stools — that's just the berry's natural color and isn't harmful.
Will bilberry turn my stool black or dark?
Yes, it can. The dark pigments in bilberry extract may stain your stools dark blue, green, or black, and occasionally your tongue or teeth too. This is harmless and temporary — it stops when you stop taking the supplement.
Can I take this if I'm on blood thinners or aspirin?
Bilberry may theoretically increase bleeding risk when combined with blood thinners or antiplatelet drugs. Check with your doctor or pharmacist before adding this product to your routine if you take any of these medications.
Will this lower my blood sugar if I'm diabetic?
Bilberry extract may theoretically increase the risk of low blood sugar when taken alongside diabetes medications. If you take diabetes drugs, mention this product to your pharmacist or doctor before starting.
