Not sure yet if it works or not!
I am using this product for 2 months so far. I have mild cognitive impairment. I think it’s still too early to tell, however, I noticed that I stay focus a little longer. But I have not seen a difference in my memory. So the verdict is still out. But there is no such big difference so far, no better, no worse. I’m still taking this supplement in hopes that it will eventually make a noticeable difference, so I will continue it for another few weeks then decide to continue or not this product. Not even sure if I should recommend it or not.
