I use a product called "Just Soy" and it's made by a company called "Interactive". Per 30g scoop is has:

120 calories
27 grams protein
0.9 grams fat
1 gram carbohydrate

Ingredients: soy protein isolate, protease I, protease II, lactase, amylase.

I take the natural, but there's also a vanilla flavour with sucralose that I find way too sweet. Interactive also makes a soy powder for women that has additional flax, spirulina, and cranberry, it's falvoured and sweetened with stevia, has 10 carbs per scoop. They make one for men too, with saw palmetto and some other prostate health promoting herbs.
