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: wheatgrass powder. Wheatgrass is the young grass of the wheat plant, sold here in powdered form.

There are no other active ingredients in this product.

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 is not established in our data. The product facts note insufficient reliable evidence to rate it for bronchitis, benign prostatic hyperplasia (an enlarged prostate gland), beta-thalassemia (a blood disorder), cancer, or the common cold.

If you're thinking about wheatgrass for a specific health reason, it's worth talking to your doctor or pharmacist about what the evidence actually shows.

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 quality and contamination concerns mean caution is wise — raw products especially may carry contamination risk, so get your doctor's clearance before use. The most common side effects reported are allergic reactions, loss of appetite, constipation, and nausea.

Since wheat is a major food allergen in the United States, wheatgrass can trigger allergic reactions in people sensitive to wheat. The facts don't contain enough safety information for pregnancy or breastfeeding, so talk with your doctor or pharmacist before use if you're pregnant or nursing.

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 before using this product if you take antidiabetes drugs (insulin or blood sugar pills) — wheatgrass may lower glucose levels and raise the risk of low blood sugar. Also double-check any medications metabolized by CYP1A2 enzymes; wheatgrass may decrease their 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.

Wheatgrass powder is generally well tolerated by mouth, but it can interact with blood sugar medications and drugs your liver processes through the CYP1A2 pathway. If you take insulin, diabetes pills, or any regular prescription, check your exact medications with the tool on this page before starting.

Talk to your pharmacist or doctor if you're pregnant, nursing, or have wheat allergies.
