Q: I need to find a protein supplement that contains no soybean. Any suggestions?

A: Many or even most whey and egg protein supplements contain soy lecithin derived from soybeans, which I assume does not fit your requirement. But as far as I know casein protein supplements don't contain any lecithin, so they may be your best your best bet -- check with wherever you buy supplements. My favorite brand for protein supplements is Optimum Nutrition -- they tend to be cheap and of good taste and quality. Most supp retailers carry them.
