Im taking 2g of GABA sometimes before sleep but have read it doenst cross the blood/brain barrier. L-on the other hand would beable to accomplish this. So can we say taking 500mg of L-Theanine before is a potential sleep aid?
I believe 500mg Theanine is too much. Besides Theanine can awake you instead of relax you to sleep. I took theanine for other reasons, and avoid in night, cause I feel awake with it.
