Barley Grass Powder
Also known as: Hordeum vulgare grass, young barley leaf, barley leaf powder, green barley
Barley grass is the young leaf of Hordeum vulgare, harvested before the plant heads and dried or juiced into a green powder. Like wheatgrass it is a staple of greens blends and is valued for chlorophyll, fiber, and antioxidant flavonoids such as saponarin. Small human studies of young barley leaf extract have looked at lipid and glucose markers, and a review has catalogued its constituents. Evidence is preliminary, so it is treated as a nutrient-dense green rather than a targeted active.
Research summary
Flavonoids and insoluble fiber studied for antioxidant activity and slowing of postprandial glucose rise.
