HelloPharmacist Scorecard of Barley Juice Powder by Nature's Sunshine

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 12, 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 leaf juice concentrate. Barley leaf juice is the concentrated extract from barley grass — the young shoots of the barley plant — processed into a powder form.

The capsule itself is an inactive ingredient that holds the powder.

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 research on barley shows it's likely effective for helping lower cholesterol (hypercholesterolemia) and supporting heart health in coronary heart disease. These ratings come from clinical trial data, so there's real evidence behind them.

Keep in mind that supplements work best alongside diet and lifestyle changes, not as replacements for them.

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 a food, but this product does contain gluten, which matters if you're sensitive or celiac. The most common side effects from barley supplements are mild digestive ones — bloating, gas, abdominal distension, and an unpleasant taste.

Some people may have allergic reactions, especially if they're sensitive to grains. For pregnancy and breastfeeding, the safety data on concentrated barley supplements (rather than barley as a regular food) isn't solid enough to give a clear yes or no — talk with your doctor or pharmacist for personalized advice if you're pregnant or nursing.

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), an antiparasitic medication, check with your pharmacist before using this product — barley may reduce how well it works.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Barley juice powder may be worth considering if you're looking to support your cholesterol and heart health and you don't have a gluten sensitivity. If you take triclabendazole for parasitic infection, check with your pharmacist first.

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.
