Concentration

A little help to mental concentration. Much better with caffeine, but I prefer to graduate the proportion myself, so it is better to buy it on its own.

Fantastic product!!!

Fantastic product: combined with caffeine allows to maintain attention and activity without nervousness problems. Combined with melatonin, excellent for falling asleep.

Help with cognition and relaxation

I take it with coffee for cognition and attention in the morning (not every day) and before bedtime for relaxation. Excellent quality

Convenient format

In capsules it is very convenient to take. I usually take one in the morning and it makes me feel better. It is recommended to take them with some food to improve absorption.

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.
