HelloPharmacist Scorecard of Wheat Grass & Barley Grass by TerraVita
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.
What’s inside
Low disclosure
This product contains 2 active ingredients: wheat grass glycerite liquid extract and barley grass glycerite liquid extract. Both are concentrated plant extracts prepared with glycerin as the carrier.
Wheat grass is traditionally used for various health claims, while barley grass has research supporting its use for cholesterol and heart health. The product also contains glycerin as an inactive ingredient (the liquid base).
Does it work?
Strong evidence
Barley grass has solid evidence behind it — it's rated likely effective for high cholesterol and heart disease risk. Wheat grass, on the other hand, doesn't have enough reliable evidence in our data to rate it for any condition, including the claims often made about bronchitis, prostate health, and cold prevention.
If you're taking this mainly for the barley grass component's heart and cholesterol benefits, the evidence supports that; for other uses, you're working without established proof.
How safe is it?
Well-documented data
Both ingredients are generally well tolerated when taken by mouth. The most common side effects are mild — nausea, loss of appetite, constipation, bloating, and gas.
Allergic reactions are possible, especially if you're sensitive to wheat or barley; both are major food allergens in the U.S. There are also quality and contamination concerns with raw grass products, so the data advises caution.
For pregnancy and breastfeeding, there isn't enough safety data on concentrated barley grass supplements to say it's fine — talk with your doctor or pharmacist before use if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before you start, double-check with us if you take antidiabetes drugs — wheatgrass may lower your blood sugar too much. Also check if you're on CYP1A2 substrates (a broad group that includes some antidepressants, anxiety medications, and others) or the antiparasitic triclabendazole, as this product may reduce how well they work.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This product may help with cholesterol and heart health, thanks to the barley grass component. If you take antidiabetes medication, CYP1A2 substrate drugs, or triclabendazole, check your medications on this page first.
If you have a wheat or barley allergy, skip it. Talk to your pharmacist about whether it fits your specific health situation.
Educational only — not medical advice; always confirm with your pharmacist. Our editorial policy · How we use AI

Wheat Grass & Barley Grass by TerraVita Drug Interactions
HelloPharmacist Interaction Report
TerraVita's Wheat Grass & Barley Grass can interact with certain medications.
The most serious concern is with antidiabetes drugs — wheatgrass may lower blood sugar levels and raise the risk of low blood sugar (hypoglycemia). Animal research suggests wheatgrass stimulates insulin release, so if you take diabetes medication, you'll want to check this before starting.
Read the full breakdown — every affected drug type, severity by severity
Wheatgrass also interacts with a group of drugs called CYP1A2 substrates — it may decrease how well your body processes them and reduce their effectiveness. Additionally, barley grass may interfere with triclabendazole (Egaten), a medication for certain parasitic infections, by lowering how much of the drug your body absorbs.
Altogether, these interactions span 271 individual medications. Use the medication checker on this page to look up your exact prescriptions before you start.
