For Dietary Supplementation: "I've always been a kind of anxious person but after years of alcohol abuse my anxiety hit the roof. I had anxiety for months on end and could find no relief. Eventually I had to start working out three times a day to actually get relief from anxiety. After days and days of researching I finally stumbled upon green tea and how can relax you. I started drinking gallons of green tea every day and start feeling a little bit less anxious. After a few weeks of doing this I decided to look into why green tea helped and found out it was L-theanine. I took these pills three times a day for three months and was finally able to breathe again. Greatest discovery ever!!! I highly recommend trying them."

For Dietary Supplementation: "I started taking this about two weeks ago for insomnia. It was combined with lavender oil as a natural sleep aid. It works for helping me to shut my brain off at night and fall asleep, but it caused severe dizzy spells and bad headaches. I also had some stomach upset. I hear that's a rare reaction, but just wanted users to be aware of the possibility. Today I had a dizzy spell so bad in the kitchen that I fell and hurt my hip. I am a 37 year old woman."

For Dietary Supplementation: "This works on my dog's anxiety, my anxiety and my college son's anxiety. We all get relief within 15 minutes of taking this. I actually found it orinally from my vet (expensive anti anxiety dog pill ingredients l theanine and meat flavoring). I keep buying tablets in the large foil bag on EBAY (the ones for humans not dogs!). It is better than an anti anxiety pill as there is no exhaustion or other side effects, just a calming feeling that allows you to relax a bit and think I buy a huge bag and that makes it cheap. The capsule form is more expensive"

For Dietary Supplementation: "I had great results. It enhanced my cognitive thinking and lessoned my memory loss. The only problem was it gave me an unbelievable body odor. I could smell it but not sure if anyone else could. No one mentioned me smelling bad. I had to stop taking them because I couldn't stand the odor. My girlfriend takes it to help her blood pressure, which the doctors couldn't seem to regulate."

For Dietary Supplementation: "I have trouble turning off my brain as soon as the lights go off at bed time. I some times get only 4 hours of sleep. This melatonin plus 200gm L-theanime is helping me go to sleep and stay asleep. I am type 2 Diebetic and I have also noticed my blood sugar levels are much better."

For Dietary Supplementation: "I have ptsd, generalized anxiety, and panic disorder from years of substance abuse which effect many facets of my health. I cannot handle stress well, my head is usually pulsing or aching, and I frequently get dizzy spells and feel lightheaded. I tried lexapro and it did not really make me feel well. It helped with anxiety and the panic attacks, but I felt emotionally flat and withdrawn from life. Since stopping the lexapro, I have resumed many of my previous daily symptoms associated with anxiety. I just started taking a liquid concentrate of l-theanine sublingually and it is nothing short of a miracle. My head is clear again and I can actually deal with my responsibilities. I feel like my life was given back to me. Highly recommended."

For Dietary Supplementation: "Military Veteran suffering from ptsd, anxiety, and insomnia. I was skeptical at first, after taking 400mg per day I definitely notice a difference. Not a miracle happy pill, but takes the edge away, allows me to feel halfway normal in stressful situations. Helps take my stomach out of knots. Sleep a little better. Can't complain, will continue to take."

For Dietary Supplementation: "I purchased this product a few days ago because it's a safe alternative to ssri'so for my son's anxiety. He's on the autism spectrum, he's 13 with severe anxiety. I have been giving him a hundred milligrams 3 times a day and he told me how much better he feels, he's so much happier. He isn't easily distracted or buried in video games. He's talkative and his conversations are appropriate. So far I think this is a miracle drug. I really hope this continues."

For Dietary Supplementation: "I take about 800 mg of L-theanine appx 1/2 hour before skating competitions to reduce my stage-fright/performance anxiety. I have also taken it before presentations at work. It works amazing well at eliminating my anxiety and allowing me to focus so that I can utilize all my practice and preparation (without being hindered by anxiety). The other benefit of L-theanine is that it doesn't make me drowsy. My Naturopath first prescribed it and now I just buy it"

For : "I use L-theanine to help with my anxiety and OCD. I take 400mg-600mg 1-2x/day as needed. It has helped to calm and relax in intense situations. An evening dose has helped calm the anxiety keeping me awake at night. It also takes the edge off of caffeine and helps calm nerves for public speaking."

For Dietary Supplementation: "I take L-Theanine Stress Formula with Calming Blend by Sundown. It greatly helps me relax at night time. It is not like taking a benzodiazipine, but definitely helps take the edge off. I am prescribed Adderall for trouble concentrating. I sometimes use it with the Adderall to decrease jitteryness. I also often mix L-Theanine with Valerian (whole root, not extract) to help me sleep."

For Dietary Supplementation: "I am a 53 year old female and have ADD. For almost 1 year, I was having extremely difficult memory problems. There weren't enough Post-it notes in the world to help relieve my anxiety about my progressing memory problem. The biggest result I have had is the ability to focus on my work, assimilate information and stay on task. I've taken prescribed medications (Ritalin, Xanax) in an effort to correct my mild ADD. This supplement is a life-saver, and job-saver for me."
