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: a wheatgrass glycerite liquid extract and a barley grass glycerite liquid extract. The wheatgrass component is prepared as a liquid extract using glycerin as the carrier, and the barley grass is similarly processed.
Glycerin is listed as an inactive ingredient—it's the base that keeps the extracts in liquid form and doesn't add therapeutic action on its own.
Does it work?
Strong evidence
The evidence for wheatgrass against conditions like bronchitis, prostate health, blood disorders, colds, and cancer is not established in the data we hold—the research available doesn't reliably support a rating. Barley grass, on the other hand, is likely effective for lowering cholesterol and supporting heart health.
If you're considering this product for cholesterol or heart protection, the barley grass content is where the evidence stands; for the wheatgrass side, the benefits remain unclear.
How safe is it?
Well-documented data
Wheatgrass is generally well tolerated when taken by mouth, though quality and contamination concerns warrant caution—raw products in particular may carry a contamination risk. Common side effects are allergic reactions, loss of appetite, constipation, and nausea.
Because wheat is a major food allergen in the US, anyone with wheat sensitivity should be aware this product may trigger an allergic reaction. Barley is well tolerated as a food but contains gluten, which matters if you have celiac disease or gluten sensitivity.
When barley is concentrated into a supplement form (rather than eaten as a grain), pregnancy and breastfeeding safety data is limited, so talk with your doctor or pharmacist before using during those times. Barley's most common side effects are bloating, gas, and an unpleasant taste.
Meds to double-check
Moderate interaction found
Before taking this product, double-check it with your doctor or pharmacist if you take antidiabetes drugs like metformin or sulfonylureas—wheatgrass may lower blood glucose and raise hypoglycemia risk (Moderate severity). Also check medications processed through the CYP1A2 enzyme pathway (Moderate severity), as wheatgrass may reduce their levels.
If you take triclabendazole for parasitic infection, confirm this product is safe for you (Moderate severity).
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 is worth considering if you're looking for barley grass's evidence-backed support for cholesterol and heart health, especially if you don't have wheat or gluten sensitivities. If you take antidiabetes medications or any blood sugar regulators, or if you're on any regular prescription (especially ones processed through the CYP1A2 pathway), check with your doctor or pharmacist before starting.
Pregnancy, breastfeeding, gluten sensitivity, and wheat allergies all warrant a conversation with your healthcare provider first.
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 Liquid does interact with medications, primarily through its wheatgrass and barley grass content.
The most serious interaction is with antidiabetes drugs: wheatgrass may lower blood glucose levels and raise the risk of low blood sugar (hypoglycemia). Additionally, wheatgrass can decrease how your body processes certain medications broken down by the CYP1A2 enzyme pathway, potentially reducing their effectiveness.
Barley grass has one documented interaction: it may reduce how well triclabendazole (a deworming medication) works in your body, though this has been shown only in animal studies so far. Altogether, these interactions span 272 individual medications.
