HelloPharmacist Scorecard of Wheat Grass 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 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: wheat grass extract at 450 mg in a 4:1 concentrated form. Wheatgrass is a young grass from the wheat plant that's been used traditionally in herbal medicine.

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 Wheatgrass product and its label doesn't state a use — see Wheatgrass'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 wheatgrass isn't established yet in our data. We hold effectiveness ratings for several claimed uses—bronchitis, benign prostatic hyperplasia (enlarged prostate), beta-thalassemia, common cold, and cancer—but all of them show insufficient reliable evidence to say whether it works.

That doesn't mean it doesn't; it means the research so far hasn't been solid enough to confirm it.

The evidence, ingredient by ingredient Wheatgrass

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.

Wheatgrass is generally well tolerated when taken by mouth, though we'd recommend caution because quality varies and contamination is a real concern with plant products. The most common side effects reported are allergic reactions, loss of appetite, constipation, and nausea.

If you're allergic to wheat, be careful—wheat and wheat products including wheatgrass are major food allergens in the U.S. Raw wheatgrass in particular carries a contamination risk, so stick with processed forms or get your doctor's okay first.

The safety data for pregnancy and lactation isn't on file, so if you're pregnant or nursing, talk with your doctor or pharmacist before taking this.

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 — Wheatgrass.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 272 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 pharmacist if you take antidiabetes drugs—wheatgrass may lower blood sugar further and increase hypoglycemia risk. Also double-check any medications that depend on the liver enzyme CYP1A2; wheatgrass may reduce how well they work.

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.

Wheat grass extract may appeal to you if you're interested in herbal support, but the evidence for what it does isn't solid yet. Be cautious if you take diabetes medications or drugs metabolized by CYP1A2—wheatgrass can affect both.

Check your exact medications with the tool on this page, and talk to your pharmacist before you start.

Wheat Grass 450 mg 4:1 Extract by TerraVita Premium Collection: Common Questions

Does Wheat Grass 450 mg 4:1 Extract by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Wheat Grass 450 mg 4:1 Extract has a known interaction with 272 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wheat Grass 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.
Will wheatgrass cause nausea or other side effects?
Nausea is one of the most common side effects reported with wheatgrass, along with loss of appetite and constipation. Some people also have allergic reactions. If you're allergic to wheat, be especially cautious since wheat is a major food allergen.
Is wheatgrass safe during pregnancy or breastfeeding?
We don't have safety data on file for pregnancy and lactation. If you're pregnant or nursing, talk with your doctor or pharmacist before taking this—they can give you personalized advice based on your situation.
Does wheatgrass really work for colds, cancer, or other conditions?
The evidence isn't established in our data. We have insufficient reliable evidence to say whether wheatgrass works for bronchitis, prostate health, certain blood disorders, common cold, or cancer. That doesn't prove it doesn't work—just that research hasn't confirmed it yet.
Can wheatgrass affect my diabetes medication?
Yes. Wheatgrass may lower blood sugar on its own, so taking it with antidiabetes drugs could push your blood sugar too low. Talk with your doctor or pharmacist before adding this if you're on diabetes medication.
Should I worry about quality or contamination?
Yes. Raw wheatgrass especially carries a contamination risk. Our data notes that quality varies, so caution is wise. Processed forms are safer than raw ones.
