My favorite supplement!!
[This review was collected as part of a promotion.] 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!!

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.

More relaxed and focused
It took about 3 weeks to notice an effect but not experiencing racing heart and palpations as often as I used to.

helps ocd thoughts and anxiety
really helpful for ocd thoughts. one of the few supplements i've tried where i experience a notable difference when i'm taking it. some days it seems to help more than others, but generally speaking, the overall trend of my anxiety and rumination is definitely down

Works great!
Works great! Taken daily to help with anxiety and promote better focus. Can feel a difference with daily use - no more spikes in nerves.
