Wheatgrass is the leafy growth of young wheat plants (Triticum aestivum). Although wheat has been used as a grain for millennia, this part of the plant has been consumed by humans for research purposes to investigate its effectiveness as a dietary supplement since the 1930s. It is packed with nutrients, including essential vitamins, minerals, enzymes, phytonutrients and all essential amino acids. It also contains antioxidants such as chlorophyll. Wheatgrass contains only 10-15 calories per teaspoon, without fat or cholesterol. It is an excellent source of protein and provides about one gram of protein per teaspoon. Wheatgrass protein contains 19 of the 22 amino acids, including all the eight essential amino acids (those the body cannot do for itself). It is thus an excellent source of protein for vegans, who often lack it in their diet. Wheatgrass is also rich in vitamins, including A, B1, 2, 3, 5, 6, 8, B12, C, E and K. It is richer in vitamin C than orange, and twice as rich in vitamin A as carrot. It contains a lot of chlorophyll. Rawpowder's Wheatgrass comes from an organic farm in Canterbury, New Zealand. The whole process is organically certified and very careful that a large proportion of the plant's original nutritional value is maintained. Organic production and processing help maintain the vitamin B12 content of the product, which is a byproduct of microorganisms on the plant rather than part of the growth structure. Store in a cool, dark and dry place. This product is suitable for vegetarians and vegans.
