The book points out that with today's science, it would actually be classed as an amino acid. But, as the author says, "Too late now."

Which sheds light on its ability to help our brains. Perhaps, under stress, this particular amino acid is hard hit on the production lines; much as stress creates "progesterone steal" and we are low on that hormone. Adding progesterone to my regimen after menopause did wonders for me.

So adding this amino acid back in makes our brains work properly. And as I have discovered, when our brains are stressed and not working properly, it becomes a physical disease also; all those signals are not being sent right to the various glands and organs. Then those organs don't work right, either.
