9L-Theanine for concentration

[LeoWinkler]

Hi guys for some reason the older I get I the more memory and concentration I lose some people told me about supplement improving memory and concentration and I found this 9l thianine online, I wonder if this is really effective, and this supplementing thing is like a long term treatment to feel any improvement, thank you.

I am sure Muskate will chime in on this one. I know he has done a bit of research on it.

For me, I keep it simple and just stick to a cup of black coffee for extra concentration.

the best thing you can do for this is simple: sleep more and better, eat better, exercise
