Life-changing Aid For A Heavy Problem Drinker
I’ve had intense anxiety (social and general) for as long as I can remember. Years ago I turned to alcohol to help—a 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 wasn’t drinking and getting drunk, but instead “dosing” throughout entire days and evenings. The moment I’d try to stop the world would come crashing down and it became a choice between feeling “normal” 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 wasn’t 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 (she’s 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 “sweet spot” 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 I’ve 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 you’ve 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! It’s my belief that when my brain finds equilibrium and begins to produce its own dopamine again (which I’ve read takes about 6 months for alcoholics and problem drinkers) that I’ll 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 I’m 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 you’ve 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: it’s over a year later, and I no longer drink, nor do I need to take Theanine (even in social situations!). My brain is clear, I’m 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 can’t 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.

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.

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.

Love it, you need this if your stressed!
I've use this supplement consistently, I am now on my last pill and Im ready to order another bottle. This has been a game changer, I noticed my eye was twitching from stress related to working with preschoolers. Within a week the twitch was gone!! I'm trying to keep my nervous system functioning & this has kept me sane it's not something you feel coming on strong but you know it works! No taste, no upset stomach, no order so easy to swallow. Please try!

Worked for autistic teen amazingly
I ordered this product for my 15yo autistic child and I am thrilled at how much this L-Theanine has worked for him. What an amazing difference. He seems so much happier now and will interact with the family now where before he seemed depressed and sad and angry and stayed in his room all the time.
