HelloPharmacist Scorecard of Horseradish Root 450 mg 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 6, 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 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: horseradish root at 450 mg per capsule. Horseradish is a pungent root vegetable traditionally used in food and herbal preparations.

The capsule itself is made from gelatin and water.

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 Horseradish product and its label doesn't state a use — see Horseradish'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 horseradish isn't established in our data. We hold insufficient reliable evidence to rate its use for respiratory tract infections, intestinal parasites, urinary tract infections, or gout.

While it's been used traditionally for these purposes, we can't claim it works based on the data we have on file.

The evidence, ingredient by ingredient Horseradish

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.

Horseradish in food amounts is generally well tolerated. But this supplement is a concentrated form, and taking large amounts can irritate your digestive tract and mucous membranes.

The most common side effects from high doses are gastrointestinal upset, diarrhea, and bloody vomiting. In rare cases, consuming large amounts has caused vasovagal syncope (a sudden drop in heart rate and blood pressure leading to fainting).

During pregnancy, the safety data advises against medicinal amounts—stay with food amounts only. During breastfeeding, there isn't enough data to know either way; talk with your doctor or pharmacist about whether this supplement is right for you.

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 — Horseradish.
  • The most serious interaction on file is rated Moderate.
  • For scale: 16 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 use thyroid hormone medications. A Moderate interaction means horseradish may interfere with how your thyroid medication works, and your levels may need monitoring.

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.

Horseradish Root may be worth considering if you're interested in traditional herbal support, but the evidence for specific conditions isn't established. If you take thyroid medication, check with your doctor or pharmacist before you start.

Anyone with a sensitive stomach should be cautious with concentrated supplements like this one.

Horseradish Root 450 mg by TerraVita Premium Collection: Common Questions

Does Horseradish Root 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Horseradish Root 450 mg has a known interaction with 16 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Horseradish Root 450 mg 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.
Will horseradish irritate my stomach?
Food amounts are usually fine, but this is a concentrated supplement. Large amounts can cause gastrointestinal upset, diarrhea, and irritation of your digestive tract and mucous membranes. If you have a sensitive stomach, start cautiously and talk with your pharmacist about the right dose for you.
Can I take this while pregnant or breastfeeding?
During pregnancy, safety data advises against medicinal amounts—stick to food amounts only. During breastfeeding, there isn't enough study data to know whether it's safe; talk with your doctor or pharmacist for personalized guidance.
Does horseradish actually work for UTIs or respiratory infections?
We don't have reliable evidence to confirm it works for those uses. While it's been used that way traditionally, we can't rate its effectiveness based on the data we hold.
What's in this besides the horseradish?
The capsule is made from gelatin and water—no other active ingredients. There are no added fillers or binders beyond what the capsule itself requires.
Is there a risk of fainting from this supplement?
Vasovagal syncope (fainting from a sudden drop in heart rate and blood pressure) is very rare, but it has been reported with large amounts of fresh horseradish. It's most likely a risk with very high doses rather than typical supplement use.
