Good complement
I have tried several similar products and this is the one that suits me best. It has its necessary activation point but without overdoing it.

It was given to me as a gift in an order and I have taken it on some days when I needed to be more alert and it does give a plus of energy.

It works
It is the first time I take it and it works. I don't feel the typical sleepiness after a morning of mental exertion.

functional!
I take it only on days when I don't sleep well and it really works, it keeps my mind active all day long. I recommend taking it only in the morning because of its long lasting effect.

Great
I take them in the morning on an empty stomach when I wake up. If you practice intermittent fasting this supplement is a plus to improve results.
