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 Sep 24, 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 powder form, concentrated as a 4:1 extract (meaning four parts fresh plant material were reduced to make one part of the extract you're taking). There are no inactive ingredients listed.

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 in our data. We hold insufficient reliable evidence to rate it for bronchitis, benign prostatic hyperplasia (enlarged prostate), beta-thalassemia (a blood disorder), cancer, or the common cold.

If you're thinking about it for one of these reasons, that's worth discussing with your doctor.

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, though quality and contamination concerns mean caution is wise. Raw products carry a contamination risk, so safety isn't established unless your doctor has cleared it.

The most common side effects are allergic reactions, loss of appetite, nausea, and constipation. Because wheat is a major food allergen in the United States, wheat grass can trigger allergic reactions in sensitive individuals — if you have a wheat allergy, avoid this product.

Side effects, ingredient by ingredient Wheatgrass

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.

Before you take this product, check with your doctor or pharmacist if you take antidiabetes drugs — wheatgrass may lower blood sugar and raise the risk of hypoglycemia. Also double-check any medication metabolized by the liver enzyme CYP1A2, as wheatgrass may reduce its effectiveness.

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 4:1 Extract Powder may interact with blood sugar medication and drugs processed through your liver's CYP1A2 enzyme. If you take antidiabetes drugs or any medication your doctor has noted is metabolized by CYP1A2, check with your doctor or pharmacist before starting.

Those with wheat allergies should avoid it. For anyone else, talk it over with your own healthcare provider to decide if it's right for you.

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.
Will this help my blood sugar?
We don't have reliable evidence to rate wheatgrass for blood sugar management. In fact, animal research suggests it may lower glucose — which is exactly why you shouldn't take it with diabetes medication without clearing it with your doctor first.
Does wheatgrass have any side effects?
Most people tolerate it well, but some experience nausea, loss of appetite, constipation, or allergic reactions. If you have a wheat allergy, avoid wheatgrass entirely — it's classified as a major food allergen.
Is it safe during pregnancy or breastfeeding?
We don't have safety data on file for wheatgrass in pregnancy or lactation. Talk with your doctor before taking it if you're pregnant, planning to become pregnant, or breastfeeding.
Is this product pure, or does it have fillers?
This product lists no inactive ingredients, so there are no added fillers, binders, or capsule materials. That said, quality and contamination concerns are a caution — make sure you're buying from a reputable source.
What does '4:1 extract' mean?
It means four parts of fresh wheatgrass plant material were concentrated down into one part of the extract powder you're getting — so you're taking a more potent form than the whole plant would be.
