Source Naturals Theanine Serene, 120 Tablets

Works within 15 minutes if taken at bedtime, it helps with sleeping. I take it as needed not daily. great for focusing and calm the body down completely , love this supplement

My kids (19&17) use this to help them sleep. My son has autism and adhd and this helps get a full nights rest. He doesn’t wake up groggy the next morning either. My daughter has ADHD and also uses it when she is stressed and having a hard time sleeping. No side effects. If you have problems going to sleep it helps a lot!

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.

Bought these for help sleeping. There's not taste to it so it's easy to swallow. Helps with focusing and it doesn't make you have the jitters. A nice buy

I give this product a four star because I have been only taking it for two weeks or so. It is early for a five star, but that is how I "feel" about the product. There are so many variables that go into sleep, age possibly being the biggest. Two years ago my quality of sleep took a fairly dramatic decline. I have worked with drugs and all sorts of behavioral modifications, such as reducing alcohol intake. None of my habits are bad. I have always been disciplined about going to bed and getting up a regular times. I have never been a big drinker or coffee imbiber, but I have always had some "transgressions." Having said all that, I continue to work on behavior and have started this supplement. Not every night, but on average, I have slept better with this supplement than prior to taking it. So far I recommend it. And, oh yes, the pills are huge! I call them horse pills. But that is not a real problem. My wife, on the other hand, could never swallow these. Net, net, I am pleased so far.
