HelloPharmacist Scorecard of Extra Strength Black Radish Root 450 mg 4:1 Extract by TerraVita Premium Collection

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: black radish root extract in a 4:1 concentration, supplying 450 mg per capsule. Black radish has a long history in traditional herbalism for digestive and liver support.

The capsule itself is made from gelatin and water — the inactive ingredients that hold and deliver the extract.

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 Radish product and its label doesn't state a use — see Radish'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 for black radish in biliary disorders and diabetes is insufficient to rate. We don't have reliable clinical data showing it works for these conditions in humans, so we can't make a claim about its benefit based on the research we hold.

The evidence, ingredient by ingredient Radish

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.

Radish is a common food and is generally well tolerated in normal dietary amounts. However, the safety profile of concentrated radish supplements — like this extract — hasn't been thoroughly studied.

A small number of people have reported allergy to radish (throat tightness and hives are possible). Large amounts may irritate the stomach lining or cause mild indigestion, though it's sometimes unclear whether that's from the radish itself or from other ingredients in a mixed product.

Raw, unwashed radish sprouts should be avoided due to food safety concerns.

Side effects, ingredient by ingredient Radish

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 — Radish.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

Check with your doctor or pharmacist before taking this product if you take any antidiabetes drug — insulin, metformin, sulfonylureas, or any other medication to lower blood sugar. The moderate interaction risk is that radish may deepen its blood-sugar-lowering effect and raise the chance of low blood sugar.

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.

If you take antidiabetes medications, talk with your doctor or pharmacist before starting this product — the radish extract may lower blood sugar further and increase your risk of going too low. Even though radish is a food, concentrated supplements are less well studied than the vegetable itself.

A conversation with your own healthcare provider will help you decide if it's right for your situation.

Antidiabetes Drugs

Theoretically, radish might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that radish extract, juice, and sprouts can reduce glucose levels. Animal research also shows that radish root juice 300 mg/kg reduces fasting and postprandial blood glucose in a rat model of diabetes, with effects similar to glibenclamide.

Extra Strength Black Radish Root 450 mg 4:1 Extract by TerraVita Premium Collection: Common Questions

Does Extra Strength Black Radish Root 450 mg 4:1 Extract by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Extra Strength Black Radish Root 450 mg 4:1 Extract has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Extra Strength Black Radish Root 450 mg 4:1 Extract 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.
Does black radish actually work for blood sugar or liver problems?
The evidence we have is insufficient to say. Animal studies suggest radish may lower glucose, but we don't have reliable human research showing it works for diabetes or liver conditions, so we can't confirm a benefit.
Can I eat radish as a vegetable if I take diabetes medication?
Yes — normal food amounts of radish are considered safe. The concern with this product is that it's a concentrated 4:1 extract, which packs far more active compound into one dose than you'd eat in a salad or cooked dish.
What side effects have been reported?
Allergy to radish is rare but possible, and can include throat tightness and hives. Large amounts may cause mild stomach irritation or indigestion. Most people tolerate it well, though concentrated supplements haven't been studied as thoroughly as the food itself.
Is this product safe to take while pregnant or breastfeeding?
We don't have safety data on file for black radish in pregnancy or lactation. Talk with your doctor or pharmacist about whether this supplement is right for you during these times.
What exactly is a 4:1 extract?
It means the extract is concentrated — four parts of the original plant material were processed down to one part of extract. This makes each dose more potent than eating the radish fresh.
