Dr. Jessica Peatross explains how nervous system dysregulation blocks deep sleep, with symptoms like an exaggerated startle reflex. She recommends liposomal GABA with L-Theanine, which may cross the blood-brain barrier and signal through gut receptors via the vagus nerve to calm anxiety at night.

You think about how hard it is to change yourself. I'm asking other people to change that are dysregulated and don't see themselves. When people are in nervous system dysregulation, they do things like they have this horrible startle reflux. They won't be able to get into a deep REM sleep at night. So sometimes I have some herbs and some supplements that will help. Things like one of my favorites is liposomal GABA with L Theanine. There was controversy before whether GABA could cross the blood brain barrier, and now that we think it does, but even if it doesn't, you have GABA receptors in your gut that attach via the vagus nerve and the gut brain, access to the brain, and you have receptors here, too. So it's modulating the the entire gut brain axis. And that really helps to calm the monkey brain at night, calm the anxiety during the day.
