HelloPharmacist Scorecard of Extra Strength Black Radish Root 4:1 Extract Powder 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 powder contains one active ingredient: black radish root extract in a concentrated 4:1 form, meaning four pounds of fresh root are reduced to one pound of extract. There are no inactive ingredients listed, so what you're getting is the extract itself.

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 facts we hold show insufficient evidence to rate black radish for either biliary disorders or diabetes. This doesn't mean it doesn't work — it means the data isn't established enough for us to say either way.

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 widely eaten as food and is generally well tolerated in normal dietary amounts. However, concentrated supplements like this one haven't been studied as thoroughly as food-form radish, so caution is warranted.

Large amounts may irritate your digestive tract and cause mild indigestion; a rare allergy has also been reported, with symptoms including throat tightness and hives. Unwashed raw sprouts should be avoided.

Side effects, ingredient by ingredient Radish

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.

Antidiabetes drugs (like metformin, insulin, and sulfonylureas) are the main concern — radish may increase the risk of low blood sugar, a Moderate-severity interaction. Check your exact medications before starting.

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 is a concentrated radish extract, not the radish you'd eat in a salad. If you take diabetes medication, you'll want to talk with your doctor or pharmacist before adding this — the blood sugar-lowering effect could be a problem.

Otherwise, digestive upset and allergic reaction are the main things to watch for. Check in with your own healthcare provider about whether it's right for you.

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 4:1 Extract Powder by TerraVita Premium Collection: Common Questions

Does Extra Strength Black Radish Root 4:1 Extract Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Extra Strength Black Radish Root 4:1 Extract Powder 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 4:1 Extract Powder 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.
Can I take this if I'm on diabetes medication?
That's a conversation to have with your doctor or pharmacist before you start. Animal research shows radish can lower blood sugar, so combined with your medication it could drop too far. Your provider can tell you if it's safe for your specific situation.
What are the side effects?
Large amounts of radish may irritate your digestive tract and cause mild indigestion. A rare allergic reaction has been reported, with throat tightness and hives. Most people tolerate normal radish amounts fine, but this is a concentrated extract.
Is black radish proven to work for anything?
The evidence we have isn't solid enough yet to say it works for biliary disorders or diabetes. That doesn't mean it doesn't — just that we don't have reliable data to confirm it.
Is this safe to take?
Radish as food is safe and widely eaten. Concentrated supplements haven't been studied as much, though, so there's a bit more caution needed. Talk with your pharmacist or doctor about your specific situation.
Why is this powder a 4:1 extract?
A 4:1 extract means four pounds of fresh radish root were concentrated down to one pound. It makes the product more potent than whole radish.
What's the difference between this and eating radish?
This is a concentrated extract — much stronger than the radish you'd eat raw or cooked. That's why there's more caution around it, even though radish as food is very safe.
