Maca is a very interesting super food and good for so many things in our body. This site gives a good break down of how beneficial it is.: http://www.macaroot.com/benefits/index.html Maca has a slightly bitter taste so it's good to mix it in with stronger tasting ingredients. You can find Maca in most health food stores. I have added various things to my shake. Today I'm having strawberries instead of carob.
