Quick Take

Evidence is preliminary — may offer modest antioxidant and digestive benefits, but don't expect dramatic effects.

Barley grass is the young leaf of the barley plant (Hordeum vulgare), typically dried and powdered. It contains chlorophyll, vitamins C and K, minerals, and enzymes. Its antioxidant and anti-inflammatory effects stem from polyphenols like saponarin and lutonarin, which can scavenge free radicals and modulate cytokine activity. Small human trials suggest modest reductions in LDL cholesterol and oxidative stress markers, and some evidence supports gut-health improvement. It is most often used by adults seeking to increase greens intake or support general wellness.

How It Works

Barley grass provides polyphenols (especially saponarin and lutonarin), chlorophyll, and superoxide dismutase-like activity that neutralize reactive oxygen species. These compounds may also inhibit pro-inflammatory signaling pathways, such as NF-κB, and support detoxification enzymes in the liver.
