It works. Very Calming.
I'm high strung and always in fight or flight mode for some reason. I have a hard time falling asleep and staying asleep, as well. It is starting to take its toll. Some research suggested this might help. I have taken it for about a week now and I do feel a little better. My sleep quality isn't much better, but this definitely has taken some of the the edge off during the day. I have no side effects and is easy to tolerate. It doesn't make me more focused or give me more energy. I'm just not as jumpy, nervous, or quick to anger. I do feel better. That is well worth the money. Plus, there is a lot of it.

There is no taste which is ok with me no smell . Has a little scooper to tell you how many mg. Works amazing for me .

Good quality and value!
Item arrived quickly and in good condition. The powder comes in a sturdy zip foil pouch, but I like to keep my supplement powders in glass containers so I transferred the powder into a 8oz glass jar. The product comes with a small plastic scoop. The powder is white and has a fine fluffy consistency. There is no distinct taste or smell. The powder dissolves easily in warm/hot water which is how take it every evening before bed. I take 100mg to 200mg l-theanine along with 3mg melatonin, 450mg magnesium glycinate , and 50 mg zinc glycinate before bed and I sleep like the dead. Sometimes I will also use 100mg to 200mg with my morning coffee or caffeine in order to smooth out the jitters from the caffeine. Love that this product has no fillers and comes with a large number of servings for a really good price. I will definitely buy again.

No caffeine side effects with this!
I purchased this to mix in with my coffee to help my body absorb the caffeine better and get less side effects like jitters, headaches, and an energy crash. This product definitely helps minimize those caffeine side effects. It mixes great with hot liquids. It takes a bit more effort to get it to mix with cold liquid, and sometimes I can’t get it all to mix into cold coffee. Overall a good value, a bag lasts forever, as the serving size is a tiny scoop. It comes with the serving scoop, which is handy too.

Great quality
This seems like a very good quality supplement. It has absolutely no smell and very little taste. You can of course taste it a little, as it is a glutamate-derived amino acid. It has a slightly umami taste like MSG, but much less strong and with more earthiness. It dissolves very quickly in water. I typically put it in green tea or dissolve it in a glass of water (in 8 oz, you can't taste it at all). I take 200-400 mg a couple times a day. I lost the scoop pretty much immediately, but I would recommend volumetric dosing anyway: just dissolve a known amount into a known about of water, and take a shot or add it to your drinks. As for whether it works: I dunno. I haven't figured out whether L-theanine is a placebo for me or not, because the effects are subtle, but it does seem to calm me down, or at least make me think I can calm myself down. It works exactly as well as suntheanine capsules have worked for me in the past. I appreciate that this company lab tests (their HPLC results looked good), everything put together it seems very pure and legit.

Most Cost-Effective Version So Far
In general, I really like l-theanine as a sleep/focus aid as well as a potential anxiety reducer. Its effects are subtle, but if you already practice mindfulness, it can be a great help to that end. As far as things I have noticed, my sleep is much deeper than it ever used to be. I still get woken up on occasion at night, but the length of time it takes to ease back into sleep from them is much shorter. As far as focus goes, I find it easier to become absorbed in tasks at work in areas I used to struggle to sit down for. As for the anxiety part, I occasionally have too much coffee and feel a nasty rush of anxiety. I used to have to wait out the feeling, but l-theanine seems to cut the time for me to come down from that anxious state enormously. I would even wager to say it gets the job done in 15 or so minutes. As for this particular brand of l-theanine, it's the most cost-efficient version I have found on Amazon so far. I prefer powder versions of l-theanine for its cost-efficiency on a general basis and I dissolve the powder in hot drinks like coffee and tea. I have noticed trying to mix it into room temperature or cooler drinks is not as easy. That being said, I highly recommend l-theanine to people with sleep/anxiety issues if they pair it with practicing mindfulness. After years of poor luck with melatonin, zzquil, etc I am really glad I have found something that works for me and serves other functions without side effects.

Great product. But upped the price a lot.
Edit: only a month later (29 Aug) price has again hiked, now to nearly £46. Abysmal. Was great, I bought this product regularly, until they upped the price from £30 to £42 in a matter of months. There’s no justification for this IMO. Since have bought elsewhere for a better price and am happy. The only upside of this product is that the bag it comes in is absolutely fantastic, long lasting.. reseals months later like new. But £12 for a better bag just isn’t worth it.

doesn't seem to work
I have always bought 'Supplemented' Theanine and it helped be through a very rough few years in my life. Not finding 'Supplemented' trading on Amazon anymore, I bought these and they tasted like rice flour and when I wake at night and can't get back to sleep, 'Supplemented' Theanine always got me asleep about 20 minutes later - NOT THESE. Three times this has happened lately and I have not found that sleep after taking these. I found 'Supplemented' trading on their own online so bought some from them and now I get to sleep 20 minutes after I take them.
