I had surgery in May, I've been trying to be careful to get my protein in, supplementing with protein shakes. My hair has been coming out like crazy! How do I know whether my protein powder is even working? I've read online that some of the types of proteins in the powders can't even be broken down & utilized by the body!

The research that I read indicates that the body can only absorb so much Protein at any one time, therefore it is important to space out your protein supplements throughout the day.

A few weeks back there was a thread on hair-loss. It might help to look up that discussion.
