Looks like you found, like me, a beneficial concoction that's palatable. Yeah, the stevia is a must add to the mix.The matcha you get seems to be top shelf. As for the tumeric Mike adds, it's also a good anti-inflammatory, like cayenne. See here: http://umm.edu/health/medical/altmed/herb/turmeric
You can also look into brewing dandelion tea. Having it with meals is supposed aid in digestion and de-tox the liver, kidneys & gall bladder. My internal medicine doc swears by it. (I'm all for de-toxification...lol)
I contacted the Hershey Co. to find out whether the special dark or the natural unsweetened cocoa contained the most nutrients. Surprisingly it is the natural, lighter type, not the special dark. https://www.thehersheycompany.com/en_us/products/product/hersheys-natural-unsweetened-cocoa-8-ounce-cans.html
