HelloPharmacist Scorecard of Wheat Grass & Barley Grass Vanilla Flavor 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.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “Wheat Grass & Barley Grass Glycerite Liquid Extract” is listed as a grouped ingredient — the label gives one combined amount (0.13 mL) without saying how much of each component you get.

This product contains two active ingredients: wheat grass glycerite liquid extract and barley grass glycerite liquid extract. The product also includes glycerin and vanilla flavor as inactive ingredients to improve taste and texture.

Both grasses are concentrated liquid extracts meant to deliver the nutritional compounds found in these plants. The two ingredients are listed as a blend, so the exact ratio of wheat grass to barley grass isn't specified on the label.

Does it work?

Strong evidence
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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Barley) (Natural Medicines).
  • On file: Hypercholesterolemia — rated "Likely Effective" (Barley) (Natural Medicines).

The evidence for wheatgrass on its own isn't well established yet—we don't have reliable data on whether it helps with bronchitis, prostate health, thalassemia, colds, or cancer. Barley grass, on the other hand, does have solid evidence backing its use for two things: lowering cholesterol and supporting heart health.

It's considered likely effective for both high cholesterol and coronary artery disease.

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • 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, but quality and contamination concerns warrant caution—stick with reputable sources. The most common side effects are nausea, loss of appetite, and constipation.

Because wheat is a major food allergen in the U.S., people with wheat sensitivity should be aware that wheatgrass may trigger allergic reactions. Barley is generally safe when eaten as food, but it contains gluten, so anyone with celiac disease or gluten sensitivity should avoid it.

As a concentrated supplement (rather than food), barley hasn't been well studied in pregnancy or while breastfeeding. Barley may cause bloating, gas, or an unpleasant taste.

Like wheat, barley can trigger allergic reactions in sensitive individuals.

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?
  • 2 of the 2 matched ingredients can interact with medications — Barley, 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 any blood sugar medications (antidiabetes drugs) you're on—wheatgrass may lower your glucose further. You'll also want to verify medications your liver processes through the CYP1A2 pathway, since wheatgrass may weaken them.

If you take triclabendazole (Egaten) for parasites, barley grass could reduce how well it works. Use the medication checker on this page to look up your exact prescriptions.

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 interested in barley's cholesterol and heart-health benefits and you're not concerned about gluten or medication interactions. Anyone taking blood sugar medication, medications processed by your liver (a very common group), or triclabendazole needs to check their specific drugs with the interaction tool below.

Talk to your pharmacist before starting, especially if you have wheat or gluten sensitivity.

Wheat Grass & Barley Grass Vanilla Flavor by TerraVita: Common Questions

Does Wheat Grass & Barley Grass Vanilla Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Wheat Grass & Barley Grass Vanilla Flavor 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 & Barley Grass Vanilla Flavor 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 cholesterol?
Barley grass in this product is likely effective for lowering cholesterol and supporting heart health, which is one of the two active ingredients here. Wheatgrass doesn't have solid evidence behind it for cholesterol yet.
Is it safe if I'm pregnant or breastfeeding?
The data isn't clear enough for either stage. As a concentrated supplement, barley grass hasn't been well studied in pregnancy or breastfeeding, and there's no safety information on file for wheatgrass. Talk with your doctor or pharmacist—they can weigh what you're trying to treat against what we don't know.
What's the most common side effect I might notice?
Nausea is the top complaint with wheatgrass, along with constipation and loss of appetite. Barley is more likely to cause bloating, gas, or an unpleasant taste. Either ingredient could trigger an allergic reaction if you're sensitive to wheat or gluten.
Does it contain gluten?
Barley contains gluten, so yes—this product is not safe for anyone with celiac disease or gluten sensitivity.
Why does the product say it interacts with so many drugs?
Wheatgrass can affect how your liver processes a very large family of medications (CYP1A2 substrates), which includes everything from certain antidepressants to some heart and cancer drugs. That's why the count is so high. Your specific medications may or may not be in that group—the checker below will tell you for sure.
