Review: Works great but "ADHD tax" not included - OK, so I have had great results using L-theanine to self-medicate for my ADHD. This powder is no exception, when it comes to how well it works as L-theanine. It's a kind of fluffy powder, with no flavor, and takes a minute to dissolve in my coffee, which is how I take it, but it works quite well in combination with caffeine to settle my brain and let me focus on things without having to wait for the hyperfixation fairy to decide to show up. But the problem is, I have ADHD! And any medication is only as good as you are at actually taking it. And that's something that you're going to have to think about and plan for a bit more with this powder, than if you're taking it in tablet or capsule form, already pre-measured and ready to go. I've heard this called the "ADHD tax," and you either pay it up front, or you pay it later on. So I just want to let anyone like me know, this is a very economical way of getting your L-theanine, compared to the pre-measured tablets or capsules, but you may need to give some thought to how you're going to use it, and where you're going to keep it, so that you actually do get the benefits.
Review: The Perfect Balm For Frazzled Nerves - L-theanine is a rare amino acid found in green tea. It induces relaxation without sleepiness. It does not inhibit speed, judgement, coordination or reflexes (it would actually aid performance on a test or a long drive). A subtle but very real relaxation takes over, much like an hour at the beach in the warm summer sun. It is best used on an empty stomach. I also use it daily at bedtime with magnesium threonate. While they do not CAUSE sleepiness, they aid in providing a mellow state that allows a wonderful slumber. Theanine (with magnesium) is not a drug. The effects are not sudden or severe (or dangerous). The powder stirs easily into coffee or tea. It can also be blended into colder liquids. An excellent product: economical and effective!
