HelloPharmacist Scorecard of EnviroDefense by Dr. Garber's

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (83 mg) without saying how much of each component you get.

EnviroDefense is a liquid supplement with five active ingredients: a proprietary blend containing black currant, briar rose, juniper, gelene, and pineal extract. The product also contains three inactive ingredients — glycerin, purified water, and alcohol — which serve as the liquid base and preservatives.

Black currant and juniper are the two ingredients we have detailed information about; they're both plant extracts traditionally used in herbal medicine.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: environmental and seasonal support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for black currant in this product is not established — we have insufficient data to rate it for Alzheimer disease, liver disease, upper respiratory infection, cough, or eczema. Similarly, we lack reliable evidence to rate juniper for GERD, rheumatoid arthritis, urinary tract infections, wound healing, kidney stones, or bronchitis.

For the other three ingredients (briar rose, gelene, and pineal extract), we hold no effectiveness information.

The evidence, ingredient by ingredient Black Currant Juniper

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.

Black currant from food is generally fine, but concentrated supplements like this one are less studied. The most common side effect reported was mild diarrhea — a small number of trial participants experienced it 2–10 days after starting black currant seed oil.

Juniper is generally well tolerated in small doses over the short term, but long-term use may irritate your kidneys and should be avoided. Topical exposure to juniper can cause skin irritation or allergies.

For juniper during pregnancy, the safety data advises against it — do not use during pregnancy. While breastfeeding, there isn't enough safety information on juniper, so talk with your doctor or pharmacist before taking it.

We hold no pregnancy or breastfeeding data for black currant, briar rose, gelene, or pineal extract — discuss these with your healthcare provider if you're pregnant or nursing.

Side effects, ingredient by ingredient Black Currant Juniper

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 — Juniper, Black Currant.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 302 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 EnviroDefense, check your medications against the following: blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel), antipsychotic or seizure medications, diabetes drugs (metformin, insulin, sulfonylureas), diuretics (furosemide, hydrochlorothiazide), and lithium. These are the medication types with documented interactions — the worst concern is the increased bleeding risk with blood thinners.

For the three ingredients we could not check (Briar Rose, Gelene, and Pineal extract), no interaction data is held.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may suit someone looking for a herbal blend, but it's not straightforward if you take blood thinners, diabetes medications, antipsychotics, diuretics, or lithium — those are the big medication concerns. If you're pregnant or breastfeeding, check with your doctor or pharmacist before starting, because we don't have enough safety data for most of these ingredients during pregnancy, and juniper is off-limits.

Run your full medication list through the checker on this page, then confirm with your doctor or pharmacist that it's okay for you.

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.

EnviroDefense by Dr. Garber's: Common Questions

Does EnviroDefense by Dr. Garber's interact with any medications?
Yes. Based on its ingredients, EnviroDefense has a known interaction with 302 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
EnviroDefense contains 5 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.
Is black currant safe to take daily?
Black currant from food is fine, but concentrated supplements like the one in this product are less studied. A small number of people reported mild diarrhea when taking black currant seed oil, usually 2–10 days after starting. Because long-term safety isn't well established, talk with your doctor about daily use.
Can I take this if I'm on blood thinners like warfarin?
Black currant in this product may increase your bleeding risk if combined with blood thinners or antiplatelet drugs. Don't start this supplement without clearing it with your doctor or pharmacist first — they can assess your individual risk.
Does juniper in this product lower blood sugar?
Yes, animal research shows juniper berry can lower blood glucose. If you take diabetes medications, combining them with juniper could cause dangerously low blood sugar. Check with your doctor or pharmacist before using this product.
What about the other ingredients — briar rose, gelene, and pineal extract?
We hold no interaction or safety data for those three ingredients. That doesn't mean they're unsafe, but we can't tell you what to expect. Mention this product by name to your doctor or pharmacist so they can review all five ingredients with you.
Can I take this while pregnant?
Juniper in this product should not be used during pregnancy — the safety data advises against it. We don't have enough pregnancy safety information for the other ingredients, so talk with your doctor or pharmacist before taking it if you're pregnant or planning to become pregnant.
Is this safe while breastfeeding?
There isn't enough safety information on juniper for breastfeeding, so it's best avoided while nursing. We also lack data on the other ingredients, so discuss this product with your doctor or pharmacist if you're breastfeeding.
