If you take "Phosphatidyl serine" for you cognitive functions, add "Alpha GPC" together with "Neurozyme" for more complete protection and improvement. Improvement has been rapid for me. My memory and focus are better. Update: Now some more months have passed. I still take PS (Phospatidylserine) daily together with "Alpha GPC" and "Neurozyme". Let me give you an example of my improvement. I speak five languages since long. But fibromyalgia, diabetes, muscular atrophy and chronic fatigue syndrome made it impossible for me to study a sixth language. My brain was in a terrible state since many years. Now I can study again, I am now studying my sixth language. I think this is a miracle, because I can can actually remember things again. I do not have "black-outs" and put things in strange places or not remembering what I was just doing anymore. "Alpha GPC" boosts growth hormone naturally, if there is a need for it. I have "adult onset growth hormone deficiency" and I can see that I am "growing younger". Although I take many "fountain of youth"- superfoods like GOJI, ACAI, Pollen, Chlorella, Colostrum etc. I think "Alpha GPC" has been vital in getting my natural hair colour back. All grey hair strands are gone! It is amazing to see. Alpha GPC improves coordination and balance. This I can notice. I no longer lose my balance, and I can hold things without losing the grip and dropping them on the floor. No more broken cups and glasses.

I just finished the one bottle. I have better sleep with one capsule a day.

Product works well, make sure you are not taking it on an empty stomach. I found it works best for me 1 hour after a meal or so.

No effect at all. This may vary or depend on the person using it. Perhaps there are other dietary or genetic factors at play, however in my case no noticeable change occurred.

Just a waste of money as far as I'm concerned. A good methylated B-Complex would have better cognitive enhancing effects IMHO. Personally I noticed zero change - apart from feeling slightly fuzzy/less focused mentally. Might work for some... But is it worth checking - at THAT PRICE!!
