HelloPharmacist Scorecard of Elderberry Chewables by NutriCology

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

This product has 2 active ingredients: bilberry fruit powder and Eldermune, which is an elderberry extract. Both are plant-based ingredients used traditionally to support immune function and eye health.

The product also contains several inactive ingredients — sorbitol, xylitol, mannitol, honey powder, mixed berry flavor, and a few processing aids — to make it chewable and palatable.

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.

Why this rating?
  • The label markets this product for: support immune and digestive health.
  • We looked for evidence on: Constipation, Irritable bowel syndrome (IBS), Lower respiratory tract infections, Respiratory tract infections, Upper respiratory tract infection (URTI), Ulcerative colitis — and 3 related terms.
  • The closest evidence on file: Bilberry is rated "Insufficient Reliable Evidence To Rate" for Ulcerative colitis (Natural Medicines).
  • Also on file: Bilberry is rated "Insufficient Reliable Evidence To Rate" for Irritable bowel syndrome (IBS).
  • Also on file: Elderberry is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections, Constipation, Upper respiratory tract infection (URTI), Lower respiratory tract infections.

The evidence supporting what these ingredients actually do is limited. For bilberry, night vision shows possibly ineffective results, while claims about age-related cognitive decline, macular degeneration, atherosclerosis, high cholesterol, and chronic venous insufficiency lack sufficient reliable evidence.

For elderberry, effectiveness data isn't established in our records for hay fever, heart disease, chronic fatigue, COPD, cognitive function, or respiratory infections. Neither ingredient has solid proof behind the claims you'll often see.

The evidence, ingredient by ingredient Bilberry Elderberry

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 2 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.

Bilberry fruit is generally well tolerated when eaten as food, but supplement safety data is limited — the safety notes advise caution with concentrated supplements. Common side effects include dark stools, flatulence, and stomach discomfort; some people report temporary GI upset or discoloration of the tongue and teeth.

Elderberry prepared from ripe, cooked fruit is generally well tolerated, but raw berries and plant parts can be toxic due to natural compounds that cause nausea, vomiting, diarrhea, and weakness. One rare case report linked long-term elderberry use to liver inflammation.

During pregnancy and breastfeeding, safety data isn't sufficient — the facts advise against elderberry supplements in these situations, though bilberry is rated likely safe.

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 — Bilberry, Elderberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 394 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 this product, double-check with your pharmacist if you're on anticoagulants or antiplatelet drugs (blood thinners), antidiabetes medications, immunosuppressants, erlotinib (Tarceva), or pazopanib (Votrient). These are the medication types where documented interactions exist.

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.

If you take blood thinners, diabetes drugs, immunosuppressants, or the cancer medications erlotinib or pazopanib, you need to check this product with your pharmacist or doctor first. Even without those medications, evidence for what this product actually does is weak.

Talk to us before starting, especially if you're pregnant, breastfeeding, or on any regular medications.

Bilberry fruit powder4 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 fruit powder full monograph & interactions

Eldermune2 drug types · 121 drugs

Immunosuppressants

Theoretically, elderberry might interfere with immunosuppressant therapy due to its immunostimulant activity.
Elderberry has immunostimulant activity, increasing the production of cytokines, including interleukin and tumor necrosis factor.

Likelihood Possible Evidence B
Pazopanib (Votrient)

Theoretically, elderberry might interact with pazopanib, potentially increasing the risk of adverse effects.
In one case, a 65-year-old patient taking pazopanib for 4 weeks for soft-tissue sarcoma developed severe nausea, loose stools, and elevated alanine transaminase and aspartate transaminase levels and was diagnosed with grade 3 liver injury. The patient reported taking elderberry supplements for 2 years, dose unspecified, and was also taking a multivitamin and a calcium supplement. The patient's symptoms and liver enzyme levels improved upon discontinuation of pazopanib and all supplements. Pazopanib treatment was re-initiated, at a lower dose, with no further evidence of liver injury. It was unclear in this case report if the elderberry supplements were derived from the berry, the flower, or the combination.

Elderberry Chewables by NutriCology: Common Questions

Does Elderberry Chewables by NutriCology interact with any medications?
Yes. Based on its ingredients, Elderberry Chewables has a known interaction with 394 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Elderberry Chewables 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?
Bilberry is rated likely safe in pregnancy and lactation, but elderberry safety data isn't reliable enough — the facts advise against elderberry supplements during pregnancy and breastfeeding. Talk with your doctor or pharmacist about what's right for your situation.
What side effects should I watch for?
The most common ones are dark-colored stools, flatulence, and stomach discomfort from bilberry. Some people get temporary GI upset. Your tongue or teeth might turn dark blue or black — this is harmless but a heads-up. If you take raw elderberry (not common in supplements), nausea and vomiting are possible.
Does this actually help with vision or colds?
For night vision, the evidence says it's possibly ineffective. For colds and respiratory infections, there isn't enough reliable evidence to know. We hold limited proof that either ingredient does what marketing claims.
Why does it say 389 interactions?
That number counts all the individual medications across both ingredients — it's not that 389 drugs will all cause trouble with you, but rather these two plant ingredients affect how that many different prescription medications work. The checker on this page will tell you which ones matter for your specific drugs.
Is this safe to take long-term?
Bilberry supplement safety over the long haul hasn't been well studied, and the caution is to avoid concentrated supplements due to lack of data. For elderberry, one rare case report linked years of use to liver inflammation. Neither ingredient has strong long-term safety data, so talk with your pharmacist about how long you plan to take it.
