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.

I been taking L- Theanine by sport research for year now. I love this supplement because I have anxiety. I take one everyday at night, when I feel like I'm having anxiety attack I take 2-3 supplements to calm myself. Boy, it helps me so much! 30 mins it's working and I have a sense of calm . I have tried other brands but sport research is the only one that really helps me. If you have anxiety and stress, I recommend this. I like taking it with magnesium at night. It works!!
