Hi all, I am doing a lot of research concerning the need for deep sleep. According to Dr. Ginevra Liptan, author of Figuring out Fibromyalgia, it is deep sleep that we are so lacking. She shows studies of fibro patients spending as little as 4 minutes in deep sleep compared to 75 minutes in a non-fibro patient. And as most of us know, deep sleep is where our muscles and cells are repaired and growth hormones are released. GABA does help improve deep sleep, but now the question is does the supplement get past the blood brain barrier?

My question is, does the Prohealth Peaceful Nights which has GABA in it have the bacteria, Lactohacillus hilgardii?
