As I already understand, the benefit of casein protein is that it is slow absorbing, and hence able to keep our bodies in a positive nitrogen balance over an extended period of time. This makes it optimal for nighttime recovery.
However, if I do not have access to casein protein, is there a hack I can do with whey protein isolate to make it digest more slowly, thereby providing the same benefits as casein regarding overnight muscle recovery? eg take it with high fibre food?
