Because it’s ground into a powder it contains the nutrients from the entire tea leaf, which means there is a greater amount of caffeine and antioxidants than found in typical green tea.  It’s been around for centuries in Japan but now it’s everywhere because of the nutritional benefits.  The high chlorophyll content makes it rich in antioxidants to stabilize free radicals, reduce cell damage and chronic disease.  It can also protect your liver, prevent cancer, promote heart health and even help you lose weight (ok maybe not in cookie form).
