Nature's Xanax
I bought these after hearing them referred to as Nature's Xanax. For awhile, I was taking them at night before bed, hoping it would help me fall asleep and wake up with less anxiety about work. It seemed to help paired with workouts. But lately, I've been taking them and pairing it with either caffeine to help me focus, or I take them on their own to help me relax. Three interesting things occurred with these specifically: One night I paired one of these with a Happy Healthy Hippie Joy-Filled supplement. The HHH tends to make me super drowsy so I thought the combo would help me sleep, but my brain was wide awake when I took these after my workout. I started to get that tired and wired feeling to the Nth degree. All of a sudden, my eyes were heavy and yet I was typing notes into my phone and researching different things for over an hour. It's what I imagine Adderall would feel like (minus the sleepiness.) This wasn't bad per se, but it was fascinating to see how intensely focused and wired my brain got. Another day, after taking this and HHH, the following morning I did an intense workout. I walked for 30 minutes and then did the elliptical with a weight vest on for about 20 or 30 minutes. I showered and got ready for a long drive to Temecula. I was stressed, as I always am before a long drive. But once I got on the road, I felt immensely calm. To the point where I almost felt like I was high or something. I have pretty bad road rage that pairs horribly with my driving anxiety, but the whole way, I didn't flinch. People were tailgating me, cutting me off, you know - the usual California driver bs - but I felt nothing but calm and happy. And the other weird thing is almost every single time (and I mean EVERY single time) I make this drive, by the time I arrive, my bladder is full and I have to race to the bathroom. But this time I showed up with no issue. Which is crazy because I drank a lot of water after my workout. One last thing I wanted to mention, after taking this and HHH more regularly, one night a few weeks ago, I made a couple of mixed drinks. And I am very aware with exactly how I feel after a few drinks. But this particular time, I felt spacey. Not in a bad way, but that same sort of high feeling. It was so interesting because I have never felt "high" after drinking. I remember saying something funny to my cat and then looking at my boyfriend and saying, "I feel like I'm stoned or something." I know that was a long one but I thought those experiences were worth mentioning. I don't think it's just because I'm taking this- I'm taking the Happy Healthy Hippie supplements, which have 6 or 7 different ingredients. I also take B vitamins and have been working out more intensely than usual. I've also been using essential oils more. So I think all these small thing combined is making a big difference. I don't think there is ever just one thing we can do or take to make a big difference in our day to day life - same as we can't just eat one fruit or vegetable over and over and expect it to keep us healthy. You have to find the right mix of everything that works for you. I definitely recommend getting some of these if you struggle with anxiety. Add it to your routine and see if it works!

Very effective!!!
Shipping was quick! I had a hard time choosing a brand but I'm glad I chose this one. It has done everything it's acclaimed to do, including slashing my appetite and sweet cravings to almost nil! I feel calmly happy, sometimes fabulous every day. I have energy and I sleep well every single night. And no I don't combine it with any caffeine. I've been using it 2 weeks now. After week one I increased it to 2 capsules a morning on an empty stomach and, I won't lie, it has worked miracles for me! Only issue I've found is I'm just as constipated when drinking green tea but that's easily rectified. The benefits are sooo much more. I'll be reordering this product before the bottle finishes. UPDATE: I keep purchasing this product. I buy the bottle by the pair. It really works exactly the way it's supposed to. Really helps with my depression spells. I work shift also so relaxation and sleep is hard to achieve. It really really really helps! I love this product!

Works wonders for sleeping, but may cause stomach upset...
Works wonders for sleeping, but may cause stomach upset...I have been using one 200 mg capsule for sleeping along with a half of one Benadryl (12.5 mg). The combination is working very well overall and I have been sleeping soundly. I am also able to get up very early with ease. When I get up early to exercise, I drink hot green tea in preparation. This supplement seems to enhance the effects of the green tea. During the day, I found that my energy level varied, but I felt calm overall everyday. One night I took the capsule and I woke up at 1:00 am with (hate to say it) explosive diarrhea and I felt nauseous. Since that time, I have found that I need to "go" more frequently in the morning using this supplement. Last night I took 1/2 of one Imodium to counteract things a bit and this helped tremendously. My diet consists of lentils and chickpeas, other legumes and chia seeds, so I probably take in more fiber than most people. I am going to follow up after more use, but so far the benefits (sleeping well and overall calmness) significantly outweigh the negatives. I did not get paid or receive a free product sample - unlike many of the reviews here.

Amazing, High Quality Product
This is my first time using L-Theanine so I don't have anything to compare to but this stuff works! I was a slight bit skeptical at first, but when paired with caffeine, L-theanine can really work wonders. Within five or so minutes I feel more focused and less stressed. Not only this but should I consume more caffeine than my tolerance is accustomed to, normally I would get jittery and lose my appetite, but if I take L-theanine and over-consume caffeine I am able to function perfectly fine. The best results I have experienced so far have been by drinking coffee and then about an hour later slamming a Wild Tiger energy drink. I have rode the lightning. It's great. 11/10 would buy again and pair with Wild Tiger.

Superb Quality and Company!
I purchased my first bottle a month ago. It arrived on time. I've taken several products of L Theanine, and didn't realize there's a difference until I began taking this product. If you're not familiar with L Theanine, it's an amino acid that calms and energises at the same time. It helps with focus and concentration. This product is one I'd recommend. Also, I'm weaning myself off coffee, and this product helps me enjoy the 1 cup I drink a day without the caffeine making me feel jittery. I also wanted to commend the company for emailing me. Apparently, I ordered after a promo that was to buy 1 and get one free. They still sent me a free bottle. That's a great customer service experience and I'm thankful.. I'll be sticking with this product for many reasons!

This brand is a keeper!
I started taking L theanine in April and have tried many different brands. This is definitely a brand that I will purchase again. I've had to increase my dose since April as I take it daily and it can start to get a little pricey. I find the price for this brand to be more than reasonable. I like to take L theanine in the morning with my coffee (the suggested ratio is 2:1) as it seems to make me a little sharper and calmer without causing drowsiness. Sometimes, I'll take a smaller dose before bed and it really helps me sleep more soundly throughout the night. These pills are easy to swallow, though I've never had any issues swallowing pills. If you do, there's always the option to open the capsule and sprinkle the powder in your drink.

L-theanine is more your fast acting every day thing to combat minor stressors, mental tasks, improve mood, and remain calm
Gaba is known for its anti anxiety and relaxing properties. However, taking straight Gaba supplements usually is not very effective as it does not cross the blood brain barrier. L-Theanine on the other hand is a unique amino acid that upregulates GABA and should be effective for the purpose of producing calmness and reducing anxiety such as a racing mind and acute stress. Clinical studies have shown that L Theanine reduces stress, improves the quality of sleep, diminishes the symptoms of PMS, heightens mental acuity, and reduces the negative side effects of caffeine. Typical dose is 200mg 1 or 2 times a day or as needed. It does not act as a sedative at this dose, L-theanine is more your fast acting every day thing to combat minor stressors, mental tasks, improve mood, remain calm (inhibiting cortical neuron excitation) and can even modulate blood pressure increases in a high-stress-response. Glutamate is the body's main excitatory neurotransmitter. Gaba is one of the body's most inhibitory neurotransmitters. Gaba helps to relax and calm, balancing against the glutamate. High copper by the way inhibits the B6 conversion of glutamate to gaba and glutamine, resulting in high glutamate levels. Has my review been of help to you? If so, would you consider hitting the "helpful" button below? I'd greatly appreciate it. Thank you!

Made me sleepy.
I bought this for mild anxiety. First time I took it (with coffee) I slept for 3 hours! Two days later, I took it at night thinking it would help me sleep and it did. I felt somewhat tired the next day, but that's kind of normal for me--so can't 100% attribute it to the product. I can definitely recommend this as a sleep aid! I probably won't try it again for anxiety, but everyone is different and it may be a fit for some.

Excellent Product!
I've ordered L-Theanine for the first time. I've read many positive reviews and decided to try out. Me and my husband are taking it now for 2 weeks. We both noted that our ability to focus on our tasks improved significantly. In addition, we are sleeping very well, restful sleep without waking up during the night. We usually take 1 capsule together with our morning cup of coffee. I intend to continue taking it.

Rilassamento, calma relax ma da problemi allo stomaco
Da un senso di calma e rilassamento quasi immediato (Soffro di disturbo d'ansia). Può dare un po di problemi allo stomaco, ma ne vale la pena.

Muchas gracias. Lo volveré a comprar.
