Regarding Protein supplementation, Soy is my choice. Like Helpmytrap said, most Soy is GMO unfortunately, and unless the supplement says 'GMO FREE' on the label, then it is not GMO free unfortunately. Also when supplementing, check that there is a 'Stamp of Accountability' from an Internationally recognized Independent organization to hold the Supplement company accountable for what is on the Label. The supplement should also state that it's made from 'food' (in the traditional human food chain), most supplements are derived from petroleum (which is also organic and natural as it comes from the ground). That is my 2 cents
