HelloPharmacist Scorecard of Dtx-gen by Genestra Brands

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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Dtx-gen contains three active ingredients: silver birch (in two forms — a bud extract and another preparation), and black currant bud extract. The product comes as a liquid and includes purified water, ethanol, and glycerin as inactive ingredients.

We don't have information in our data on what roles the silver birch forms play in this formula. Black currant bud extract is traditionally used in herbal medicine, though solid evidence for its effects on conditions like upper respiratory infections, cough, or skin conditions like eczema isn't established.

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 on black currant for the conditions this product may target — including Alzheimer disease, liver disease, upper respiratory infections, cough, and eczema — is insufficient. We hold no effectiveness data on the silver birch ingredients.

If you're considering this product for a specific health goal, talk with your doctor or pharmacist about whether the evidence supports its use for your situation.

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 berry in food amounts is considered safe, but concentrated supplements like those in Dtx-gen are less studied, so use caution and check with your doctor first. In a trial of over 2,000 people taking black currant seed oil at a higher dose, a small number experienced mild diarrhea a few days after starting.

Our data does not include pregnancy or breastfeeding safety information for this product. If you're pregnant, nursing, or planning either, talk with your doctor or pharmacist before using Dtx-gen.

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 Dtx-gen, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel) — black currant may increase bleeding risk. Also confirm if you're on phenothiazines (antipsychotics), where there's a theoretical risk of seizures.

We could not check the silver birch ingredients against your medications.

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.

Dtx-gen is a three-ingredient herbal liquid that hasn't been studied enough to confirm it works for conditions like cough or upper respiratory infections. The main caution is its black currant content, which may interact with blood thinners and certain psychiatric medications — so check your exact drugs before starting.

If you're pregnant or nursing, ask your doctor or pharmacist whether this product is right for you.

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.

How can one product interact with so many drugs?

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 on blood thinner medication?
Not without checking first — black currant in Dtx-gen may raise bleeding risk when combined with blood thinners or clot-prevention drugs. Talk with your doctor or pharmacist before starting.
Is this safe to take while pregnant or breastfeeding?
We don't have safety data on this product during pregnancy or lactation. Ask your doctor or pharmacist for personalized advice before using it.
What's the liquid supposed to do?
The ingredients are traditionally used in herbal medicine, but we don't have solid evidence that this product works for the conditions it may target — like upper respiratory infections, cough, or eczema. The science on black currant for these purposes is considered insufficient.
