I just got my free trial today so I can't say how effective they are, but I just want to say that this article and the reviews are complete BS. All of the ingredients are clearly listed on the bottle and website (B3, B6, and a Nootroo blend made of caffeine, GABA, Bacopa Monnieri, Alpha GPC, L-theanine, Phosphatidylserine, L-tyrosine, Vinpocetine, Huperzine-A). Also, all you have to do is read the fine print (which unless you're an idiot you always do) and it tells you that you'll be charged every month if you don't cancel. That's literally how every free trial works. So don't blame the product because you can't read.
Bottom Line: Yes, I would recommend this to a friend
