An item I always purchase I have recommended L-Theanine for years. It was recommended to me by an MD. It helps to calm and relieve stress by taking "the edge" off thinking that is spinning too fast. Just a month ago I saw that Dr. Amen was in favor of it (he suggests 400 mg) a day. The Swanson brand is the best value for the cost. May 3, 2013
L-theanine this product helps me relax, i take it at nite, before bed May 3, 2013
Stress reliever Used widely in Japan, this amino acid is free of caffeine and calms the alpha brain waves to help deal with stress. It also aids sleep patterns. May 1, 2013
Didn't quite cut it I didn't get the noticeable relaxation response that the others here evidently got. This brand is good, no bad reaction and can't compare it to others. It's probably an individual reaction and perhaps other brands would work better for me, though I'm not going to try them out just now. April 30, 2013
Wonderful and calming I wouldn't be without Suntheanine. It promotes relaxation without drowsiness. It is the ONLY form of L-theanine that has a patent (Taiyo). All other forms of L-theanine are not nearly as good as this. In addition to promoting calm relaxation, it also mitigates the effect of caffeine 'jitters.' If you're not familiar with SunTheanine, by all means treat yourself to a bottle. It's magic. April 24, 2013
great product really helps to reduce stress. l would totally recommend it to others. April 23, 2013
Not Uptight Anymore Had never heard of this amino acid before having someone suggest it to me. Being in a lot of stress and tempers beginning to flare, I ordered this L-Theanine product and after about three weeks, I felt more relaxed and things didn't seem to bother me as much. I was taking one capsule a day for a while and decided to take one twice a day and am now feeling so much better! Wonderful! April 15, 2013
Truly effective I bought Suntheanine to see if the claims for it were valid. I can say they truly were. To help calm and relax you,to take the edge off stress and to give a satisfying nights sleep, this is the product. It especially helped my wife, who is very "highly strung". She is definitely easier to get along with and smiles more than she has done for years! April 11, 2013
I think it's great When I first started taking this product I could feel an overall change in my mood. I had a better sense of well being. I supposed if I stopped taking it I would be able to confirm its effectiveness. April 7, 2013
Wont Go A Day Without It I absolutely love this product! I start my day out with it and sometimes end my day with it. I have noticed a distinct overall calmness since I have been taking it. I have recommended L-Theanine to most of my friends and family. I don't go a day without it and for the great price, I wont have to. March 28, 2013
Get Leveler My homepathic recommended this supplement. When I found Swanson's brand at such a great value I was sold. I am a repeat purchaser. It brings a calm without any drug affect. Buy it and give it a try. March 23, 2013
Swanson's L-Theanine My husband and I think this product works great. We like the way it seems to relax us. We make sure we never run out. March 22, 2013
Very useful supplement! I keep this one in my arsenal to help combat grouchy moods. Taken with a couple other supplements, & this is one I refuse to live without! Great positive benefits! Best price anywhere! March 22, 2013
Helps me sleep This is a great product, not real expensive and works for good sleep. The only thing is, it won't last all night. I have to take one around 1 AM to sleep the entire night on top of the first one I take before bed. But for the price and effectiveness, I would recommend it. March 21, 2013
takes the edge off Good stuff! An amazing product and an affordable price. Increase clarity of mind as well as relaxing....good product March 18, 2013
Best purchase ever. This product works great. I will definitely recommend it. March 12, 2013
Did not work for me I gave this product five leaves because I do believe that it is a good product, unfortunately I did not like this product. I did not feel well after I took this. I wish it would work for me, it is supposed to have great benefits. March 12, 2013
delivers as promised This product does help one achieve an overall sense of calm -- it's subtle but definitely there, without drowsiness. Have been taking it twice a day for a month. March 3, 2013
Recommended It helps me unwind, without making me sleepy. February 22, 2013
A natural alternative for calming I would never take any product that interferes with my mind or ability to function optimally, so this product is a gentle answer to help bring forth a state of calm equilibrium, naturally! February 20, 2013
The product didn't work as well for me as it did for a woman on a certain doctor's tv show. She claimed she went from sleeping one hour a night to sleeping eight hours a night from using it. For me, I fall asleep about two hours faster and wake up about half as often than before. So I gain about three more hours overall of sleep. But I wake up slightly foggy-headed. I will purchase L-Theanine again. February 20, 2013
Wow! Decided to try this after reading the reviews. I was loooking for something to take my stress level down a notch at work. This absolutely does the trick and more. Marked mood improvement. When I do get ticked, it seems to pass quickly. I definitely feel happier while taking this supplement. If you get grumpy and sometimes just feel generally unhappy, pop one of these when you get up in the morning and life is good. February 18, 2013
Anti-stress One capsule at bedtime helps me sleep better and wake up relaxed. On days of pressure, I take one more at breakfast and things go smoother, without any energy drop. An effective supplement. February 16, 2013
Best Product Being a faithful Swanson's customer for many years this product is the best purchase ever. When I discovered it and began using it regularly I am convinced it keeps me on an even positive outlook and spirits and less stressed feeling. I also started my husband on Suntheanine L-Theanine. We both benefit from the product and wouldn't be without it. Thank you Swanson's for all your great products. February 15, 2013
Great Stuff! I would buy it again This product really helps relax you and keep your mind focused on the day. PROS: Less stressed Better feeling of wellness over all. CONS: None, deal with it. February 7, 2013
