### ⭐⭐⭐⭐⭐ Review
*by M***O on 26 June 2013*

So my Theanine Serene arrived in the mail today.. WOW. I’m impressed. I’ve been using suntheanine by Solgar for awhile now as part of my caffeine + L-Theanine nootropic stack for steady focus and concentration. For those uninitiated, L-theanine is a nonessential amino acid found almost exclusively in the camellia sinensis plant (green tea). It helps to counteract the negative effects of caffeine by calming the excitatory neurotransmitters in the brain that cause anxiety. So, I found the Solgar brand to be very subtle and it took a few days to really kick in, and even when it did the effect was negligible unless I took up to 300mg twice a day and that was on top of also taking Alpha BRAIN which contains 200mg of theanine as well. I can say after about a half hour of taking Theanine Serene I was so super chilled out. I went to work a couple hours later and nothing seemed to phase me, which is a big deal considering what a high stress environment it is. To me; that’s all the proof I need. I’ve researched everything in it: magnesium, GABA, taurine, theanine, and Holy Basil leaf. That’s why I decided to go with this particular brand; because it combines so many elements which act upon GABA brain receptors towards the same effect. So it’s a multi-pronged attack. I imagine that’s why it’s so effective. OF COURSE something to remember is that 1.) These are supplements that you may or may not already be partially procuring through diet already and so therefore may have some degree of tolerance if you experiment with them. And 2.) Individual physiology differs from person to person (weight, metabolism, age, etc.) dictates how you’ll react. If anyone reads this and decides to give it a chance, give it a week at least or more based on the aforementioned variables to allow the components to pass the blood/brain barrier and saturate your receptors.
