Thats what I thought! Free form glutamine has the exact same efect as glutamate - and its in almost all commercially sold whey protein powders, especially the isolate forms of whey. Unless it is totally undenatured raw protein powder its a big no-no.
Im so upset to find this out.
My brother also has been taking glutamine powder in the morning and he adds whey protein every morning to his oatmeal! I just called him to let him know.
Watch the video!!
EDIT I found the article below by Dr.Blaylock. The glutamine is being transformed to glutamate by the body when unusual amounts are given, such as in glutamin powder and whey protein powders with free glutamine. It happens during manufacturing that the complete protein is broken down and free glutamine forms.
