HelloPharmacist Scorecard of Bilberry & Lutein Once Daily 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 3 of its 3 active ingredients.
  • “Bilberry Fruit Extract” is listed as a grouped ingredient — the label gives one combined amount (160 mg) without saying how much of each component you get.
  • “Lutein” is listed as a grouped ingredient — the label gives one combined amount (6 mg) without saying how much of each component you get.

Solaray's Bilberry & Lutein Once Daily contains 3 active ingredients: zeaxanthin, bilberry fruit extract (which provides anthocyanosides), and blueberry fruit extract. Zeaxanthin and the anthocyanosides from bilberry are carotenoids — pigments your body uses to support eye health.

Blueberry adds additional antioxidants in the same family. The capsule also contains inactive ingredients like cellulose, gum arabic, magnesium stearate, water, and silica, which are standard binders and fillers.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Eye health and vision support.
  • We looked for evidence on: Age-related macular degeneration (AMD), Asthenopia (eye strain), Cataracts, Central serous retinopathy, Choroideremia, Diabetic retinopathy — and 4 related terms.
  • The strongest evidence on file: Zeaxanthin is rated "Possibly Effective" for Age-related macular degeneration (AMD) (Natural Medicines).
  • Also on file: Blueberry is rated "Insufficient Reliable Evidence To Rate" for Cataracts.
  • Also on file: Zeaxanthin is rated "Insufficient Reliable Evidence To Rate" for Cataracts, Glaucoma, Asthenopia (eye strain), Macular telangiectasia type 2.

The evidence for this product is mixed. Zeaxanthin is possibly effective for age-related macular degeneration (AMD), a common eye condition in older adults.

For age-related cognitive decline and Alzheimer disease, the data on zeaxanthin isn't strong enough to say whether it works. Blueberry extract shows possibly ineffective evidence for high blood pressure, and for conditions like anxiety, athletic performance, and heart disease, the data is insufficient to know if it helps.

Neither ingredient has strong evidence for the other uses listed in the research.

The evidence, ingredient by ingredient Bilberry Blueberry Lutein Zeaxanthin

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 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both zeaxanthin and blueberry are generally well tolerated at typical supplement doses. However, freeze-dried blueberries can cause constipation, diarrhea, nausea, and vomiting — in one trial, about a quarter of participants taking 50 grams daily quit in the first week due to stomach upset.

Regarding pregnancy and breastfeeding, zeaxanthin and blueberry extract are rated Likely Safe, though supplement safety hasn't been thoroughly studied in these populations. Food amounts are fine, but talk with your doctor or pharmacist before using concentrated supplements if you're pregnant or nursing.

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?
  • 2 of the 2 matched ingredients can interact with medications — Blueberry, Zeaxanthin.
  • The most serious interaction on file is rated Moderate.
  • 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 your medications if you take antidiabetes drugs (insulin, metformin, sulfonylureas, or others), because zeaxanthin and blueberry both may theoretically lower blood sugar. Also double-check if you're on buspirone for anxiety or flurbiprofen for pain — blueberry may slow how your body clears these drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you're interested in eye health support, especially for age-related macular degeneration, this could be worth considering. Anyone taking diabetes medication, buspirone, or flurbiprofen should check their exact medications with the tool on this page first.

If you experience nausea or digestive upset, start with a lower dose or check with your pharmacist — it may be the freeze-dried blueberry component.

For each ingredient in Bilberry & Lutein Once Daily 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 Fruit 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

Blueberry Fruit 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 & Lutein Once Daily by Solaray: Common Questions

Does Bilberry & Lutein Once Daily by Solaray interact with any medications?
Yes. Based on its ingredients, Bilberry & Lutein Once Daily 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 & Lutein Once Daily contains 3 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.
Will this help my eyesight or prevent macular degeneration?
Zeaxanthin in this product is possibly effective for age-related macular degeneration. That means there's some evidence it may help, but it's not proven. For other eye conditions and cognitive decline, the evidence isn't strong enough yet to say whether it works.
Can I take this if I'm pregnant or breastfeeding?
Zeaxanthin and blueberry are both rated Likely Safe in pregnancy and lactation, though concentrated supplement safety hasn't been well studied. Food sources are fine, but talk with your doctor or pharmacist before using this supplement to make sure it's right for your situation.
What side effects should I watch for?
Most people tolerate this well. However, the freeze-dried blueberries in here can cause constipation, diarrhea, nausea, or vomiting — in one study, about 26% of people taking 50 grams daily had stomach problems bad enough to quit. If that happens, try a lower dose or stop and talk with your pharmacist.
What's the difference between zeaxanthin, anthocyanosides, and lutein?
They're all carotenoids — natural pigments that support eye health. Zeaxanthin and lutein are similar compounds found in leafy greens and berries. Anthocyanosides are the antioxidant pigments in bilberry and blueberry that give them their dark color.
Is this product the same as just eating blueberries?
No. This is a concentrated extract, so you're getting much more active compound in one capsule than in fresh or whole berries. That's why the safety concerns focus on the extract form — eating regular blueberries doesn't carry the same gastrointestinal risks.
