Matcha powder and skim milk and truvia, woohoo!
Hate to rain on your parade, but if you add milk (no matter the fat content) to your tea, the caseins in the milk will prevent you from absorbing a lot of the nutrients (and for the same reason, you shouldn’t drink milk in combination with your multivitamin). As far as I know, using soy milk or any other non-dairy milk instead will not have the same effect. Source (one of many): http://www.sciencedaily.com/releases/2007/01/070108191523.htm
Soy, rice, and almond milk should NEVER have caseins! Just another reason to go dairy-free
