Barley Juice Powder Concentrate [Vital Nutrition] is derived from young barley plants, which have a strong resistance to disease and fungus. Barley greens are also a superior source of chlorophyll, the nutrient-rich byproduct of photosynthesis that makes plants green and is chemically similar to human blood. Barley greens provide 30 times more vitamin B1 and calcium than milk, seven times more vitamin C than oranges, and nearly five times the iron of spinach. Each capsule contains 480 mg barley juice powder. Take 8 capsules daily with water on an empty stomach.
