HelloPharmacist Scorecard of Elderberry-V by Douglas Laboratories

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 11, 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.

Elderberry-V contains a single active ingredient: elderberry extract. Elderberry is made from the berries of the Sambucus tree and has been used traditionally to support immune function and respiratory health.

The product also contains cellulose and vegetable stearate as inactive ingredients — standard capsule fillers.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Immune support and respiratory health.
  • We looked for evidence on: Upper respiratory tract infection (URTI), Lower respiratory tract infections, Respiratory tract infections, Rhinosinusitis, Common cold, Influenza — and 1 related terms.
  • The closest evidence on file: Elderberry is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections (Natural Medicines).
  • Also on file: Elderberry is rated "Insufficient Reliable Evidence To Rate" for Rhinosinusitis, Upper respiratory tract infection (URTI), Lower respiratory tract infections.

The evidence for elderberry isn't well established yet. Our data shows insufficient reliable evidence to rate it for allergic rhinitis (hay fever), cardiovascular disease, chronic fatigue syndrome, chronic obstructive pulmonary disease, cognitive function, and respiratory tract infections.

That doesn't mean it doesn't work — it means the clinical studies to prove it aren't solid enough to call it established.

The evidence, ingredient by ingredient 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 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.

Properly prepared elderberry products made from ripe fruit are generally well tolerated. The risk comes from raw or unripe berries, seeds, leaves, and bark, which contain cyanogenic glycosides and can cause nausea, vomiting, severe diarrhea, weakness, dizziness, numbness, and even stupor — but cooking eliminates that toxin.

One case report linked elderberry to autoimmune hepatitis (liver inflammation) in a patient with an underlying autoimmune condition; symptoms resolved after stopping the supplement and starting treatment. During pregnancy, there isn't enough reliable safety information, so it's best to avoid it.

The same goes for breastfeeding — the data to know either way isn't there. Talk with your doctor or pharmacist if you're pregnant or nursing and thinking about this product.

Side effects, ingredient by ingredient Elderberry

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 — Elderberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 121 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 you start, double-check this product against immunosuppressants (drugs that weaken your immune system after transplant or for autoimmune disease) and pazopanib (Votrient), a cancer medication — both are rated Moderate severity concerns.

The bottom line

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

If you take immunosuppressants or pazopanib, skip this product — it could work against your therapy. If you're on other medications, check them with our tool first.

Otherwise, properly prepared elderberry is generally well tolerated, though the evidence for what it actually does isn't strong yet.

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-V by Douglas Laboratories: Common Questions

Does Elderberry-V by Douglas Laboratories interact with any medications?
Yes. Based on its ingredients, Elderberry-V has a known interaction with 121 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Elderberry-V 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.
Is this safe to take while pregnant or breastfeeding?
There isn't enough reliable safety information about elderberry in pregnancy or while breastfeeding to say yes or no. Talk with your doctor or pharmacist for personalized advice based on your situation.
What happens if I take raw elderberries instead of this supplement?
Raw or unripe elderberries, plus the seeds, leaves, and bark, contain toxins that can cause nausea, vomiting, severe diarrhea, weakness, dizziness, and numbness. Cooking eliminates the toxin — that's why properly prepared products are safe but raw ones aren't.
Does elderberry actually work for colds or the flu?
We don't have enough reliable evidence to say it works for respiratory tract infections. The science just isn't solid enough yet to call it established.
Can this boost my immune system?
Elderberry has immunostimulant activity — it does increase immune signaling — but we don't have reliable evidence it improves immune function in a way that matters for real-world health.
What are the inactive ingredients?
The capsule contains cellulose and vegetable stearate — both standard, inert fillers that help hold the supplement together.
