HelloPharmacist Scorecard of Horseradish 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.

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 a single active ingredient: horseradish extract in powder form, concentrated at a 4:1 ratio. There are no inactive ingredients listed — just 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 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 as a remedy isn't established in our data. We don't have reliable evidence to rate it for respiratory tract infections, intestinal parasites, urinary tract infections, or gout.

If you're considering it for one of these uses, talk with your doctor about whether the science supports it and what other options exist.

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 is generally well tolerated in food amounts. However, this is a concentrated extract powder, and large amounts can irritate your digestive tract and mucous membranes, causing stomach upset, diarrhea, or bloody vomiting.

In rare cases, consuming large quantities has triggered a sudden drop in heart rate and blood pressure (vasovagal syncope). During pregnancy, safety data hasn't been established — avoid medicinal amounts.

While lactation safety ratings differ across sources in our data, medicinal use during breastfeeding hasn't been well studied; sticking to food amounts is the safer approach. Talk with your doctor or pharmacist if you're pregnant or nursing and considering this product.

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.

If you take thyroid hormone medication, talk with your doctor or pharmacist before using this product — horseradish may reduce its effectiveness. No other medication interactions are documented for the ingredients we could check.

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 extract is generally well tolerated in food amounts, but this concentrated powder can irritate your digestive tract if you overdo it. The key concern is thyroid medications — if you take thyroid hormone, check with your doctor or pharmacist before adding this.

For any use, start low and talk it over with your own healthcare provider first.

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

Does Horseradish 4:1 Extract Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Horseradish 4:1 Extract Powder 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 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 pregnant?
The safety data advises against medicinal amounts during pregnancy because it hasn't been well studied. Talk with your doctor or pharmacist about whether this product is right for you right now.
What are the most common side effects?
In food amounts, horseradish is generally well tolerated. But in large amounts — like what you'd get from a concentrated powder — it can cause stomach upset, diarrhea, or gastrointestinal irritation. In rare cases, very large amounts have caused a sudden fainting episode.
Is horseradish proven to work for UTIs or respiratory infections?
The evidence we have is insufficient to rate horseradish for those uses. If you're considering it for a urinary tract infection or cough, talk with your doctor about treatments with stronger evidence behind them.
Can I use this while breastfeeding?
There isn't enough data to know either way about medicinal use during breastfeeding. Sticking to food amounts is the safer approach, and it's worth checking with your doctor or pharmacist for personalized advice.
What does '4:1 extract' mean?
It means the powder is concentrated — four parts of the fresh plant were processed down to one part powder. That makes it much stronger than just dried, ground horseradish, so you're getting a more potent dose.
