Life-changing Aid For A Heavy Problem Drinker
Iโve had intense anxiety (social and general) for as long as I can remember. Years ago I turned to alcohol to helpโa couple of drinks when I felt anxious, or before a social situation calmed everything down, and I felt as though I could manage. But it quickly spiraled out of control to the point where I wasnโt drinking and getting drunk, but instead โdosingโ throughout entire days and evenings. The moment Iโd try to stop the world would come crashing down and it became a choice between feeling โnormalโ by drinking something, or dealing with nonstop racing heart, shortness of breath and severe depression. Well the latter was absolutely horrible to live with, so I kept choosing the former. I was hiding liquor bottles in the house so I could pop back to a room and take a nip the moment I would start to feel overwhelmed. Obviously this wasnโt sustainable. My epiphany occurred when my senior dog had a seizure, and to cope, I begged my partner to go and pick up a pint of alcohol, just to get through the worry and fear (sheโs okay now). I realized SOMETHING had to change. I read and did research and decided to try L-theanine. This brand was the first brand I tried. I began with 2, and then upped the dose each day until I found the perfect โsweet spotโ for me at 1200mg*. That seems like a lot, but my brain had been depleted of natural anxiety defense for years. The day I took at the amount for the first time changed the entire course of my future. For once I was able to breathe, to think clearly, to feel calm and normal without a drop of alcohol. The effect lasted nearly 12 hours, and that night I slept like a baby. I tried it the next day, when that familiar anxiety and urge to drink crept up... and it worked again. Within the hour, my heart began to beat normally, and I was calm and content, and once again drifted off to sleep that night genuinely looking forward to waking up (a rare thing when you drink every night). So far Iโve been sober for three weeks, and I feel amazing. There are no sedation, stimulating or uncomfortable side effects, it kicks in within 30-60 minutes (depending on whether youโve eaten), and one dose lasts me 12+ hours. I have zero urge to drink, I sleep great, my mood is amazing, and my typical ADHD brain is clear and focused! Itโs my belief that when my brain finds equilibrium and begins to produce its own dopamine again (which Iโve read takes about 6 months for alcoholics and problem drinkers) that Iโll only need the L-theanine on difficult or stressful days. For someone who spent every waking moment suffering the pain of severe anxiety, I could really cry from joy for this mental, physical and emotional reprieve. For once Iโm truly excited about the future. *1200mg is a high dose, and over the recommendations based on studies looking at changes in alpha waves (200-400mg). I am not a doctor or health practitioner, nor am I suggesting people follow my dosage right out of the gate. If youโve never had substance abuse issues, you likely will not need such a high dose. Research and consult your doctor before adding any supplement, especially if you intend to take more than the recommended amount. I began with two (the highest recommended dose) and did not increase that dose until 24 hours later. I stopped at 1200mg because that was the dose that gave me the relief and results I was looking for; I do not intend to exceed that amount for myself in the future. Edit to Update: itโs over a year later, and I no longer drink, nor do I need to take Theanine (even in social situations!). My brain is clear, Iโm genuinely happy, and so so glad I discovered this. Quitting drinking can be hard, but this absolutely saved my sanity and my life. I still will always keep a bottle on hand, and I canโt recommend it hard enough for folks desperately looking for aid. Good luck out there friends!

Helps with sleep
As I have gotten older good sleep is harder to come by. I researched that L-Theanine would help with that and be better than taking melatonin. I am happy to report that it does a nice job helping me get mellow. I seem to be able to achieve longer deep sleep and I still can wake up in the morning without feeling drugged or hungover like regular sleeping pills do. I trust this company and have a few other products from them and think it is a great product.

Helps Me Turn the Volume Down on My Brain
I added this to my daily routine to help with focus and relaxation, and I've been really happy with it. It helps take the edge off without making me feel sleepy or foggy. I especially like using it on busy or stressful days when my brain has about 47 tabs open at once. High-quality softgels, easy to take, and definitely staying in my supplement lineup.

Helpful
Just a few days in. Took 2 capsules the first day. 4 the next day. So far so good. Experienced my usual anxiety-inducing stressor and was fine, not dysregulated. I think it helped!

Relaxed & Happy In Wisconsin, Zzzzzz.... and ahhh...!
Did you know that L-Theanine can help with anxiety in addition to several other optimal health benefits. I have been so pleased with this product! Since this product helps with both rest and clarity, I gave it go to see if it would help with anxiety, which I suffer have from time to time. I hate to take prescription meds and this product has helped me cut back on nearly every medical prescription. As a middle-aged woman, I am thrilled! Thanks Sports Research! Another update on the benefits of this awesome product! On nights that I have trouble sleeping and I feel exhausted in the morning and need a little nap, but feel too stressed to sleep, I will take one tablet of L-theanine and it will help me to relax and take a little nap if needed. If a nap is not needed, my mind is still more sharp and clear than it would be without this product. Interesting how it can both help me relax and sharpen my focus! Great product Sports Research! Update: After numerous months of using this product, I am pleased to report that it works! I use L-theanine to help me to relax and go to sleep at night. I take it about 30 minutes before putting my head on the pillow and usually it puts me out and I wake feeling rested! Thanks Sports Research! I purchased the L-Theanine because a friend said it helps her to fall asleep. Skeptical, I researched and purchased the Sports Research brand because of high ratings and the fact that it was made with coconut oil, etc. It did not disappoint! I have been able to relax and fall asleep without any other aids or medication since using this product. It also calmed my scalp psoriasis! Nothing has helped that in over 10 years. Impressed, I then ordered the SR Biotin made with coconut oil; between the two, I am sleeping better and am no longer constantly scratching my head! Yay! Update: still Love this product! I use it to help me to relax or to sleep. Works like a charm.

This stuff is an all Natural MIRACLE!
I've been experiencing some pretty intense anxiety in my life lately due to a lot of stress (layoffs at work, graduate school, family life, wrecking my car, etc). I went to the Dr. to check my options, where my Heart Rate is normally 60 BPM it has been at 100 BPM. I have had the shakes, the tight chest, breathing has been a little labored, very edgy and irritable, and I cry over EVERYTHING ALL THE TIME (I litterally cried over a dead pigeon in my parking garage at one point!). My poor fiance has not known what to do with me the past couple of weeks! I hate taking pharmaceuticals and have taken 5-htp and L-Tyrosine supplements in the past to help with some slight depression (which also worked wonders!). I started doing some research on natural remedies and supplements for Anxiety and found some great articles (Dr. Daniel Kalish is a wonderful resource for natural treatments for just about anything!) my research informed me L-Theanine is a great alternative to your Xanex Anti-anxiety meds but it doesn't cause any drowsiness (and I refuse to touch any kind of anti-depressant pill). I read from my research to take 200-400mg of L-Theanine 2-3 times a day but not to exceed 1200mg total in a day (I am not a medical dr. and found this in my own research! Before you take this medicine or deicde what dosage you are going to take be sure to do your own research on this supplement to see what works best for YOU!). I also read that you want to look for a product that has Suntheanine in it (which is a brand of L-Theanine from Japan that is the purest and extracted the best for the most effective results). I tried 200mg last night on my way to one of my graduate classes after learning a massive layoff was happening the next day at work, also didn"t have my homework done for that class and was quite honestly a mess. By the time I got to class I noticed I was so much calmer! My chest was still slightly tight but my breathing, shaking, and tenseness had subsided dramtically and I felt....normal. Today I took 400mg on an empty stomach and took it with my morning coffee (researchers have found doing a stacking method with a ratio of 1:1 with L-Theanin and Caffeine helps with anxiety but the caffeine helps give you a very good focus and mental sharpness through the day) 2 hours later (and might I add today is the day of the layoff's) I feel completley calm, collected, happy and focused!! So far this stuff has been God Sent. It has spared me my sanity, my graduate career, and my relationship! Also, this brand makes the supplement with Coconut Oil and with its wonderful qualities makes me feel even better and gives me total peace of mind to be taking this supplement! My favorite thing so far has been the immediate results and relief I've gotten from this supplement....I dont have to wait 6 weeks to see if it works! This will become a permanent fixture in my daily supplement supply! I HIGHLY Recommend this stuff if you have anxiety, ADD, focus problems, or mood problems!!!

Finally Sleep!!!
Okay this is the first review I've ever posted on here. I've been an Amazon Prime customer for years. I make tons of purchases on here (133 in the last six months) but I've never left a review until now. I decided to write this review because this may be the best product for me and life changing product ever! Also, I wasn't given any kind of discount or promotion for this review!!! I have suffered with insomnia off and on for years. The main contributor has been the fact that I've had to do lots of on call and shift work. I've tried virtually everything at one time or another from OTC antihistamines, herbs, minerals and other amino acids like kava, valerian, magnesium, passion flower, tryptophan, melatonin, zinc, ashwagandha, hops, chamomile on and on with no real luck. I have also tried prescription sleep medication like Ambien, Lunesta, Sonata, Valium, Rozerem to name a few. Ambien works pretty well, and I have continued use with it over the years off and on but really wanted to eliminate it all together especially because I'm very limited on how often I'm allowed to take it due to my employment. I also don't like the idea of having to take any type of medication habitually and that's not what it's intended for. My current employment also forces me to change back and forth from nights to days and vice-versa which makes it impossible to get into a good sleep routine. On a whim after reading some reviews, I decided to give L-theanine a try for my sleep issues. I had read that some people take it during the day and some at night. Some people combine it with coffee for more focus, some use it for anxiety, others sleep. It sounded like different people used it for different things. I was interested in it only to help me with my sleep (primarily falling asleep). I know individual body chemistry can play a huge role in the response each person has to different medications/supplements. I was just hoping that this amino acid would finally be the solution I've been trying to find for so long. I went ahead and ordered it and all I can say is WOW!!! I've only been using it for five days, but my sleep has been amazing. I personally take it about 30 minutes before bed. I can actually feel the effects from it in about that time. For me it feels slightly dissociative. I don't necessarily feel sedated but I don't linger on any thoughts. I almost feel like I'm wrapped in a blanket and my mind goes clear or black. Any thoughts that I start to have flash away. I know that sounds weird, but it's the best way I can describe it. The days before I tried it I had been working nights and wasn't able to fall asleep until around nine in the morning. That is so frustrating. I would lose not only the time laying in bed at night but also half the next day. As soon as I started taking these around 11:30 PM I was out sometime between 12:00-1:00 AM every time. I have woke up a couple nights, but I was able to go back to sleep. I've been able to get a minimum of seven hours of sleep every night I've used these. I did try a different brand 100mg dose, and it did not work for me. I always like to use the lowest dose possible of anything. It looks like I will be continuing with this brand and dose. Time will tell for me if this supplement/amino acid continues to work the miracle it has the last few days. I can honestly say I'm ecstatic at the results so far!!! Obviously this won't work for everyone (nothing does) but this has reacted great to my body chemistry and accomplishing what I want it to (deep sleep with fast onset). I definitely recommend trying it for anyone who has suffered insomnia/fatigue like I have. I wouldn't wish that on my worst enemy!!!!!!!!!

The magic pill for sure! The best product!
So, let me start off by saying how this product is seriously such an amazing one! I am so glad that I tried and love it! Here is a little background about myself... I suffer from really bad migraines and tension headaches (at least twice a week from 3-4 days), basically almost most of my weekdays, due to stress from work. It was at the point that I would come home, shower, and go to bed (avoiding everything, including my own family). This was really at the point that it would prevent me from doing the things that I enjoy and even taking care of my kids. To make my long story short, I tried a variety of things to see what could help, including acupuncture, seeing a chiropractor, migraine prevention and emergency pills, change in my diet... and nothing helped. The emergency pill does help, but only for the moment and the pain usually comes back again within 24-36 hours after taking it. I got to the point that my neurologist prescribed me to try something that only brought out the worst side effects on me that I had to take a few days off as it affected my nervous system. I freaked out and felt like I was running out of options and that these headaches were ruining my life completely... until I started researching for natural supplements and I came across this amazing product. After reading and checking out some reviews, I decided to order a bottle and give it a try (I mean, what could I lose at this point?!...). Let me tell you that since the second day that I started taking it, I have been feeling the goodness of this product; the magic! It has been over 2 weeks already, and I have only gotten one mild migraine (yes, only on migraine within the last two weeks) which this never happened before. Definitely reducing the number of migraine episodes that I get. I take it at night, right before bed, and I wake up easily, feeling energized, clear minded, and focused. Iโve also noticed that I am more focused and I donโt get as stressed as I was compared to before taking it. I feel like this helps me staying relaxed but focused. Not groggy at all! I even told one of my coworkers who also suffers from migraines to give this product a try since it worked for me. Iโm no doctor whatsoever, but this was definitely worth the try. I plan on continuing taking this and even buying more bottles of L-theanine. Moreover, I highly recommend it! The quality of the product is great and I donโt get any after tastes. I look forward to less headaches (as itโs heloing me at the moment) and hope that it continues working.

No headache Best theanine so far, worth the money
This is a 5 star product. Ive tried Naka, organika, and a few other l theanine products from other brands always ending up with headaches or gastrointestinal discomfort. This one takes the cake. Coconut oil, gelatin and beeswax capsule which is amazing and sun theanine so there are no impurities. No headaches. amazing results
