L-THEANINE 250mg
Excellent with caffeine
Caffeine is that simple, basic supplement that never fails, but sometimes causes those spikes, which then also cause a crash. This is an excellent modulator, providing energy without those spikes

L-THEANINE 250mg
Correct.
I have a special immunity to caffeine, or at least to its negative effects, but I started taking it since, due to situations, my sleeping hours have been reduced and I needed to know if I can sleep with more quality, and apparently it is working for me, since I feel more repaired since I started taking it.

L-THEANINE 250mg
Operates in cycles
You notice its effects improving cognitive performance but as it is a sustained effect, as soon as you balance you will no longer notice those effects. I would take it in 3-4 day cycles.

Excellent for anxiety
If you have anxiety and intrusive thoughts THIS IS YOUR SUPPLEMENT! I never get tired of recommending it to everyone. 100% effective, after 45 minutes of ruminating on thoughts, you forget everything.

I love it
It does the job, better concentration, more focus and it also keeps you relaxed. I would even say it puts you in a good mood. Highly recommended if you are a person a little scattered and you find it hard to concentrate.
