Wow. Just wow!
I like most have some stress and along with it comes random but steady sleep disturbances. Tried L- Tryptophan, Melatonin, Tylenol PM, warm milk, and a host of other things over time. Not much luck sadly. But thats just me. Tried this to add to my barrage of attempts. Pretty powerful to say the least. Yes the pills are big but they snap in half with ease. I did half the dose- so 1 pill at first to see. I couldn't believe how I felt. I mean again- THIS IS MY EXPERIENCE ONLY and maybe Im deficient in Taurine or whatever else thats in it or who knows what else as I havent been eating much anyways to get proper nutrients and aminos so that could be it- perhaps its the ingredients combined? Who knows…but I was actually sorta stoned within an hour of taking it. I sat laughing at the dumbest videos for 2 hours. I felt like a kid. I was yawning by 1.5 hrs and almost crashing but in a good way. I woke up 5 hrs later amazed I had actually fallen into a solid sleep phase. Im normally up every couple of hrs because my brains on overtime. I thought - wow I didnt even take a full dose! It was still early morning so I decided to take another half of one. Quick snap and swallow. The half a pill size is perfect. Within another half hour- off to la la land yet again. It sorta reminded me of when I used to take prescription Ambian. Id highly suggest it to be taken at bed time or at a time your able to rest. Im not groggy at all the next day. But I am a weird calm. I can honestly say its a strange soothing washing over me that I feel. Like staring out at the ocean. Serene. Wholeness. Thats pretty amazing considering its all natural. I think I will order a few bottles to keep on hand to stock up. I have suggested this to a few friends already. If you feel like your going to explode or implode from your life and struggle to relax- you should really try this formula. Id recommend half dosing till you know how itll affect you, and certainly dont plan on doing many activities lol. Dont drive on this. Read the warnings if you take Lithium. Which I dont. I did try other “herbal” smokes prior to this that also did not work- but I would not mix anything with this. Its a very powerful concoction. Atleast for me. I simply love its affects. Relaxation and sleep have been given back to me and Im grateful! Ill probably throw out half the older bottles of stuff Ive tried that did not work now. You have nothing to lose. Its cost is great especially when its on sale to. I hope everyone has the same results I do! I was taking Gaba by itself prior and it didnt even compare to this. Plus your oddly quiet and calm inside the next day. Im not sure Ill need to take 2 pills at once. One does it for me. Maybe on the weekends Ill try 2 if I know I can monitor the next day affects. Pretty awesome stuff. You have nothing to lose in trying it as I said, for me its a great product. Works like a dream. Im curious if its affects will eventually wean down as I become tolerant. Being in Nursing I did my homework on all the ingredients and doses they used which are all in line and appropriate. I may then have to take two or cycle on and off to maintain its affectedness. We shall see. 10 stars!

Better than a sleep aid
This stuff WORKS. Though maybe TOO well, ha. I struggle with a racing heart in the mornings or waking up in the middle of the night with a racing heart. The suggested dose is 2 tablets. The tablets are huge. But they knock. Me. Out. I am “relaxed” in the morning - but mainly because I am so tired! lol. I tried also to just take one, and it helped a bit but it was still a drag to get out of bed. But it knocks me out and keeps me asleep. And no racing heart in the mornings! I am going to try to just take a half of one and see if that helps me not feel so groggy when I have to wake up so early. Or maybe take it mid afternoon instead of right before bed?

My all-time favorite anxiety reliever
I cant tell you how many people I've offered this to at work. This puts me in the BEST mood at work. This stuff relaxes me so my authentic self shines through. I stay productive at work...unloading freight trucks and I unwind quicker when I come home. This formula has never let me down. Bad things don't stick....like water off a ducks back. You will NOT be disappointed. The pills are huge so I chew 2 and Im off to a great day. They have no taste and break down fast. Just do it. You will be shocked how tolerant and resilient you become.

Great product, but with a side effect.
I purchased this mostly because of my insomnia and sleep issues that I had since I was a child. This product for sure helps with that. I can feel the effects about 20mins to 1 hour in. I get really relaxed, less stress, less anxiety and ready for bed. The one issue though, and this can be a me thing. It makes my poop horrible. I'm not talking smell but texture and color. When taking this (Please excuse the words in the next part) it makes my poop very muddy and black. When I stopped taking it the next few days my poop returned to normal. Solely because of that I have to remove a star because I'm not sure I want to continue taking this. Its a mess lol.

MY SECOND REVIEW - UPDATE
This is my second review - a sort of update since I have been taking Source Naturals Theanine Serene. Since I first started taking this supplement in February, I must admit I was a bit skeptical. However, I wanted something that was more natural based. Since then, I have to say, I have noticed a difference. It took about a week as I "wasn't paying too much attention" to this. I just wanted it to do its work, or not and "see." On the bottle it states to take at least two tablets; I like to be on the side of caution and take less and start with one and that's usually all I take per day. SOMETIMES I take a second, but I can say maybe it's been two or three days since February till now that I have taken two in a day. For me, one per day is sufficient. Also, to my surprise and pleasantly, and I really had paid absolutely NO attention but all of a sudden it just dawned on me one day, I noticed I was NOT having Restless Legs any longer! Serious! I have been suffering from this syndrome for well over 15 plus years and for the past 10 it had gotten worse (at night mostly). I don't suffer from any major neurological problems, just Restless Legs where when I am in bed at night I have to constantly move my legs for almost 1/2 hour or more so I need to get out of bed stretch. move them around, etc., etc. Sometimes during the day if I sit still too long, I get it at times, too. If anyone has this, they know what I mean. It can be rough. Anyway, when I say all of a sudden, it dawned on me, and disappeared. This seemed to have happened since I have been taking this supplement, Theanine! This was the ONLY change in my diet or anything else and the funny thing is I had stopped taking the supplement (not on purpose) for about five or six days and low and behold; my Restless Legs Syndrome were returning again and then again I realized I had not taken that supplement! I think, not only does this supplement "calm" and help one with stress, but it must do something with some neurological thing at least with me, with regards to my RLS. I can't tell you how great that is. If anyone reads this; and has RLS, of course I would hope you talk it over with your physician/neurologist, etc. I have (I also see a Neurologist for Migraines), so I just don't take it upon myself to "doctor" myself. I just wanted to share results. Remember, everyone is different; so speak with your physician first! Thanks for reading.

Better than most
Why did you pick this product vs others?: Slightly better than the rest. Bought based on podcast reccommendation for this specific combination of elements. Typically these things never work for me after first few weeks. I took 200 magnesium glycinate three hours after dinner. An hour later, I took two of these. I slept quickly. I did wake at 2:30 mid-dream and went back to sleep til 6:30am. Noticed a positive edge to my dream state. Will report back after the month mark.

Beneficial dose for sleep
I used to take this product back 30 years ago. Fast forward to today & researching all the new “social drinks” are just a micro dose version of this product. Plus they are expensive at $2-$3 per dose, such a waste of money. This product makes sense & the dosage is actually beneficial. I take 1 at bedtime and sleep great
