As far as the protein goes, not a big deal. I am not a fan of GMO foods, but there are a couple of things to consider here.
First, is that over 96% of the US soybean crop is GMO, so it is VERY hard to find non-gmo soy products.
Second, is the amount in the product. It is listed as one of the last ingredients, so there can't possibly be much soybean oil in the product to begin with.
Again, in a perfect world, no GMO's would be great; but I do believe in some sort of moderation as well. I wouldn't want to eat bowls of GMO soybeans every day, but having some protein powder that has a TINY amount of soybean oil doesn't really bother me. I do have options that don't have it, but they do cost quite a bit more
