HelloPharmacist Scorecard of Wheat Grass and Barley Grass Combination 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

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.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This powder contains 2 active ingredients: barley and wheatgrass, both in powdered form. They're blended together in a proprietary mix, which means the exact proportion of each isn't disclosed 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 Barley's overall clinical evidence instead.

Strong

Strong clinical evidence supports Barley 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 ingredient's overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Natural Medicines).
  • On file: Hypercholesterolemia — rated "Likely Effective" (Natural Medicines).

Barley powder has solid evidence behind it for heart health. It's rated Likely Effective for lowering cholesterol and for supporting heart disease prevention.

The evidence for wheatgrass isn't established in the data we hold.

The evidence, ingredient by ingredient Barley

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.

Barley is generally well tolerated as food, but it contains gluten — so skip it if you're gluten-sensitive or have celiac disease. The most common side effects from oral barley are bloating, gas, belly distension, and an unpleasant taste.

Allergic reactions can happen in sensitive people, ranging from mild itching in the mouth to, rarely, serious reactions like swelling of the throat or anaphylaxis. For pregnancy and breastfeeding, the safety data on concentrated barley supplements (like this powder) is thin.

Barley as regular food is considered likely safe in pregnancy, but we don't have enough information on concentrated supplements either during pregnancy or while breastfeeding — talk with your doctor or pharmacist about whether this product fits your situation.

Side effects, ingredient by ingredient Barley

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 — Barley.
  • The most serious interaction on file is rated Moderate.
  • For scale: 1 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.

If you take triclabendazole (Egaten) for a parasitic infection, check with your doctor or pharmacist before adding this product — barley may reduce how well the medication works.

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.

If you're looking to support cholesterol and heart health and you don't have gluten sensitivity, barley powder is well studied and generally well tolerated. Just check with your doctor or pharmacist first if you take triclabendazole, are pregnant, breastfeeding, or have any gut conditions that make bloating or gas a problem.
