non-dairy protein supplement

In order of preference:

Jay Robb egg white protein - tastes good and does not separate, do not heat or you get scrambled eggs

GNC soy protein isolate - average in every respect

Lipotropic gemma (pea) protein - very sweet with an under taste reminicent of sweet peas; more palatable if mixed with strong flavors like PB2 (powdered eanut butter) or hershey's unsweetened cocoa powder; or in protein coffee or tea

Vegan rice protein - not exactly gross but not delicious, drink it quickly because it separates easily 

Netrition.com or Vitamin Shoppe for all except soy.  GNC.com for soy.
