HelloPharmacist Scorecard of Elderberry Force by New Chapter

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 23, 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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: black currant and European black elderberry extract. Black currant provides gamma-linolenic acid (GLA), a fatty acid with potential effects on blood clotting and inflammation.

European black elderberry is a concentrated plant extract; we hold limited safety and interaction data for it as a supplement. The capsule itself is an inactive ingredient (the container).

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Black Currant product and its label doesn't state a use — see Black Currant's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold on black currant doesn't establish that it works reliably for Alzheimer disease, liver disease, upper respiratory tract infection, cough, or eczema — the data shows insufficient reliable evidence to rate it for any of these. For the elderberry extract in this product, we don't have effectiveness ratings on file.

If you're considering this supplement for a specific condition, talk it over with your doctor or pharmacist about what the broader research shows.

The evidence, ingredient by ingredient Black Currant

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.

Black currant berries eaten as food are generally well tolerated, but concentrated supplements are less studied. A small number of people taking black currant seed oil reported mild diarrhea starting 2–10 days after beginning treatment.

The safety data for concentrated black currant supplements is limited, so it's worth checking with your doctor first. We don't have safety or adverse-effect data on file for the European black elderberry extract.

Side effects, ingredient by ingredient Black Currant

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 — Black Currant.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 140 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 Elderberry Force, check with your doctor or pharmacist if you take blood thinners or antiplatelet medications (like warfarin, aspirin, or clopidogrel) — black currant may increase bleeding risk. Also check if you take phenothiazines (psychiatric or anti-nausea drugs) — there is concern about a possible interaction affecting seizure threshold.

We could not check the elderberry extract against medications, so run all your medications through the search tool on this page.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is designed to combine two berries, but the evidence for their effectiveness at the conditions listed isn't established in the data we hold. More importantly, if you take blood thinners or antiplatelet drugs (like warfarin or aspirin) or phenothiazines, you need to talk with your doctor or pharmacist before starting it — the black currant can interact with these medications.

Black Currant2 drug types · 140 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, black currant seed oil might increase the risk of bleeding if used in combination with anticoagulant or antiplatelet drugs.
Gamma-linolenic acid (GLA), a constituent of black currant seed oil, appears to have antiplatelet effects.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, black currant seed oil might increase the risk of seizure in patients receiving phenothiazines.
Black currant seed oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines, although there is no evidence that black currant seed oil causes seizures. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure. In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily, which contains GLA, was added. One of these patients had a prior history of seizures.
