Matcha is reported to have the nutritional value of up to 10 cups of regular green tea and up to 137 times more antioxidants than regular green tea.
Matcha literally means "powdered tea." With matcha green tea, you're drinking the actual leaves, which have been dried and then stone ground into a fine powder.
To make matcha tea, plants are covered with shade cloths before they're harvested. This increases chlorophyll content and creates a vibrant green colour that's rich in antioxidants.
Because matcha is made from high-quality tea, and the whole leaves are ingested, it's a more potent source of nutrients than regular green tea.
