L-THEANINE 250mg
I'm hooked
I love the effect it has on me. I don't take it with caffeine and I don't need it, it calms me down but activates and focuses the mind, and that helps a lot in a head that is spinning more than thinking.

L-THEANINE 250mg
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.

L-THEANINE 250mg
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.

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

L-THEANINE 250mg
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.

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.
Minimum purchase of units!
