HelloPharmacist Scorecard of Organic Barley Grass by BulkSupplements.com

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 Jul 11, 2026

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: barley grass powder. Barley grass is the young plant harvested before the grain develops, and it's used in supplement form to deliver concentrated amounts of the plant's nutrients.

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).

The evidence supports barley for two cardiovascular uses. Barley is likely effective for lowering cholesterol (hypercholesterolemia) and for reducing coronary heart disease risk.

These ratings reflect solid research backing the ingredient's ability to help with those two conditions.

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 grass is generally well tolerated as a supplement. The most common side effects are mild gastrointestinal ones — bloating, gas, and abdominal distension — along with an unpleasant taste.

Because barley contains gluten, it's not suitable if you have celiac disease or gluten sensitivity. Allergic reactions are possible in sensitive people, and in rare cases can be serious — including anaphylaxis.

There isn't enough safety data on concentrated barley supplements during pregnancy or breastfeeding to know whether they're safe; talk with your doctor or pharmacist for personalized advice if you're pregnant, trying to become pregnant, or nursing.

Moderate interaction found

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), a parasitic infection medication, you'll want to check with your pharmacist before using this product — barley may reduce how well it works.

Triclabendazole (Egaten)

Theoretically, barley might decrease the clinical effects of triclabendazole.
Animal research suggests that a diet supplemented with barley can reduce the bioavailability of triclabendazole when taken concomitantly. This effect has not been shown in humans.

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.
Does barley grass actually lower cholesterol?
Yes — the evidence is solid enough that we rate it likely effective for lowering high cholesterol and for reducing coronary heart disease risk. That said, a supplement works best alongside diet and lifestyle changes, not instead of them.
Will this upset my stomach?
For most people, no. The most common side effects are mild — bloating, gas, and some abdominal distension. An unpleasant taste is also reported. If you're sensitive to fiber or new supplements, start with a small dose.
