Top-shelf supplement & company
I've been using SR L-Theanine for a few years on and off. I recently got my fiancée to use it too. It really helps reduce the stress and mind racing when you have a lot going on. It also helps with immune function directly and indirectly by reducing stress. I like the high quality of SR supplements. I used to buy them on Amazon but Amazon has gotten crazy with fake products so now I order directly from SR, just takes a little longer to get. Also, the support team is nice too.
