HelloPharmacist Scorecard of Wheat Grass 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 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 in a 4:1 concentrated powder form. That means the extract has been concentrated down, so you're getting more of wheatgrass's compounds per dose than you would from the fresh plant alone.

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 treating specific health conditions isn't established in our data. We hold effectiveness ratings for bronchitis, benign prostatic hyperplasia (enlarged prostate), beta-thalassemia, the common cold, and cancer — and for all of them, the evidence is insufficient to make a reliable call.

If you're considering this product for a specific reason, talk with your pharmacist about what the current science actually supports.

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 as a food, but the safety data comes with an important caveat: quality and contamination concerns mean caution is wise. Raw wheatgrass products in particular may carry a contamination risk.

The most common side effects people report are nausea, loss of appetite, and constipation. Because wheat is a major food allergen in the United States, anyone sensitive to wheat should know that wheatgrass can trigger allergic reactions.

Our data notes there isn't enough safety information to recommend this unless your doctor approves, so it's worth asking before you start.

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.

If you take antidiabetes drugs or medications broken down by the liver enzyme CYP1A2, check with your pharmacist before starting this product — both interactions are Moderate severity and could affect how well your medications work or your blood sugar control.

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.

Wheatgrass extract is generally tolerated, but it's not your move to make alone if you take diabetes medications or drugs metabolized by the liver enzyme CYP1A2 — both need a conversation with your pharmacist first. If you're allergic to wheat, skip it.

The evidence for what this product actually does for specific health conditions isn't established yet.

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

Does Wheat Grass 4:1 Extract Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Wheat Grass 4:1 Extract Powder 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 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.
Does wheatgrass actually work for colds, cancer, or other conditions?
Our data doesn't establish that it does. For bronchitis, the common cold, cancer, and several other conditions people ask about, the evidence is too thin to make a reliable call. If you're thinking about this for a specific health reason, ask your pharmacist what the current science actually supports.
Will wheatgrass make my blood sugar drop if I take diabetes medication?
It could. Wheatgrass can lower blood glucose and trigger insulin release on its own, so taking it with your diabetes medication carries a real risk of your blood sugar dropping too low (hypoglycemia). You need to talk to your doctor or pharmacist before you add this product.
What are the side effects?
Most commonly, nausea, loss of appetite, and constipation. If you're allergic to wheat, wheatgrass can trigger an allergic reaction since it's a wheat product. Because quality and contamination concerns exist with raw products, our data notes caution is wise — check with your doctor first.
Is it safe to take while pregnant or breastfeeding?
Our data doesn't include safety information for pregnancy or lactation, so there isn't enough to know either way. Talk with your doctor or pharmacist for personalized advice before using this product if you're pregnant or breastfeeding.
What does '4:1 Extract' mean?
It means the wheatgrass has been concentrated — the extract is four times as strong as the original plant material. So you get more of wheatgrass's compounds in a smaller dose than you would from fresh wheatgrass.
Does it have any fillers or other ingredients?
No inactive ingredients are listed for this product — what you're getting is the extract powder itself.
