For Whey: Dymatizeor any Hydrolyzed whey. Next best thing is one that is nanofiltered like TruNutrition Sciences Whey and Isolate which are very low in lactose. LG Lipotropic has concentrate in it but is low enough to be called lactose-free and it is cheap. Otherwise you are looking at Egg, Soy, .
Are you lactose intolerant or just trying to rule things out?
