Spectacular
Theanine has proved to be a highly effective natural tranquilizer. I thoroughly recommend it.

I do not notice anything
In my case at least, I don't notice anything at 250 or 500mg, with or without caffeine, which doesn't mean that it doesn't work, but at least it hasn't helped me.

Good
It is quite good, when you do not need the acceleration of caffeine.

As always
HSN is a guarantee. It arrives quickly, well packaged, the product corresponds to the description and it works. I have yet to see how it goes in the medium to long term.

Theanine plus melatonin: equals deep sleep.
I have found the perfect blend to sleep perfectly, no matter how many shifts I have to work. I mix melatonin with theanine, this supplement is as effective as any other, but it's at a better price. And I get many hours of sleep without waking up.

I mix it with the evobrain, between work and the competitive exams, I don't know if it's a suggestion but I feel more like studying.

Good quality/price, but it does not relax me as much as it is said.

Perfect
I use them together with the caffeine pills to give me energy but to take away my nervousness. They are perfect to combine them and I no longer have those cardiac problems.

To calm nerves a little
It is a good product to calm some stress and anxiety in everyday life. Do not expect miracles, it is not a pharmaceutical product, but it helps. In addition, it does not leave you "plof", but you can stay focused. The capsules are not very large and have an adequate concentration. In addition, the price is very reasonable. A "must" in my supplements.
