Doctor's Best L-Theanine Contains Suntheanine, Helps Reduce Stress & Sleep, Non-GMO, Gluten Free, Vegan, 150 mg (DRB-00197), 90 Count...

This has been wonderful! Helps take edge off and feel more relaxed.

Obviously there is no flavor, as it is a capsule that you swallow, but I guess I could say I do not experience any after taste, once it is in my stomach, LOL. I researched, and purchased this item, as I was finding that my low carb focus dietarily, was - while good for me otherwise - seemed to be resulting in some unwelcome changes in terms of increased adrenaline. I had switched from my caffeinated coffee to decaf, and was experimenting somewhat unsuccessfully with teas, rueful smile. While feeling better through out the day, I found I still had, on occasion, episodes of waking from sleep with some pretty silly worries, that just refused to be "put to bed". This supplement without question helps in that regard. After I take even one dose, I sleep like the proverbial baby, with no waking, and no negative after effects the next morning/day. I do not take it every night. I only take one, as directed, the next night before bedtime, if I have one of those wakeful nights the night before. Laughs, somehow that just gets more confusing each time I rewrite, but I hope the idea that, even if you only use it occasionally, It Works!

L-Theanine was first recommended to us by a psychiatrist for our younger son when he was in 4th grade and developed a tic due to stress of a teacher in a new school. It didn't do anything for the tic, but our older son took some one day, and really felt great! He's in high school and had been feeling pretty stressed. He said it helped him feel calmer and less anxious while not losing any focus. The good thing is L-Theanine is an amino acid; it's found in green tea. It can cross the blood brain barrier and has a positive effect on alpha-brain waves; it has a relaxing effect, reducing physical and mental stress, boosts mood and cognition. It also acts in concert with caffeine to boost cognitive performance. L-Theanine has been tested on small groups of people with significant sleep disorders, and while it's not overly sedating, it does affect alpha waves and tends to be relaxing. It helps those people with sleep, as it does with anxiety. My husband and I recently added it to our ZeeBooth subscription list of supplements when we read an article in Life Extention Foundation's December 2013 magazine about supplements one should consider adding when facing the flu. It was incredibly timely! No sooner did I get the magazine, read it, stock up and get enough for all the kids, than I got socked with a sinus infection/flu. I have never before gone without a course of antibiotics, but this time really wanted to make the effort. I hunkered down with my supplements - L-Theanine included, ate cooked mushrooms (natural anti-viral) several times, as well as maintaining good hydration, and stayed in bed. I finally made it through my very first painful sinus infection/flu w/o antibiotics! So, yes, I heartily recommend L-Theanine! I'll keep buying it for myself, my husband, and our kids!

I have a cat named Nicholas who is a marker. I found a product on here, Fizzion, that takes care of the smell & stains, but still wanted to find something that would address the root of the problem. He's also sometimes aggressive towards my other cats, and easily stimulated. Three strokes along his back, fine - four, he tries to bite. I asked my vet about Prozac or Xanax, because I heard that sometimes they can be used on animals. Instead, my vet recommended Anxitane, an all natural calming supplement that contains L-theanine. It worked great - but it was expensive. $30 for thirty tablets. My budget didn't allow for an additional $30 a month, but I really wanted to help him. I looked for the active ingredient on the bottle and saw "suntheanine" so I bought a bottle of tablets and ground them up to mix in his food. Didn't work. I mentioned it to a cat behaviorist friend, and she corrected me - I have to use Suntheanine "L-theanine". Not just regular Suntheanine. There's a difference. I found Doctor's Best L-theanine and bought a bottle. Bingo. Big difference in his behavior. His marking was reduced tremendously, but that could also be attributed to the Fizzion (I've reviewed that too - it's phenomenal. But the change in behavior was awesome. In fact, I started giving it to a couple of my other cats too. One is a pariah and is terrorized by the other cats, so he's very stressed. He has his own room, but even that only helped so much. After starting this supplement, I noticed a marked reduction in his stress level. The Anxitane tablet is 100 mg and the dosage is 50mg 2x a day - you break it in half. The Doctor's Best capsules are 150 mg, so you have to open them up and mix a third of one into wet food 2x a day, or mix a whole capsule into three servings - share with other cats or just store the other two servings. I just ran out of it and noticed my cats began reverting to old behavior almost immediately. I'm not going to run out again!
