How to mix superfood/herb powders evenly?

I know this is a dumb question but I cant find the answer anywhere. Im going to make my own "superfood" powder batch, very similar to dr schulze put it in one of my glass jars. Question is how do I get them in evenly so every tablespoon I use will pretty much have the same amount of ingredients in each. Do I just put all the powders in one container and stir? Thank you in advance. Tweet
