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.

Brałem 3 kapsułki do pierwszego posiłku. Działanie nasila się sie wraz z upływem czasu. Zaobserwowałem: lepsze skupienie, poprawa nastroju oraz pojawia się zapał do działania (być może to efekt placebo), ale jestem w stanie za taki efekt zapłacić:-)

Purchased for my dad who had stroke two years ago. trying to help him with memory loss issue. We can see his improvement little by little since the second bottle of Jarrow Formula,Alpha GPC. So I will continue to purchase it!

I have not actually consumed any of my purchase so far but I am very satisfied with the service that I received and how quickly the produce was sent to me. At this point I would certainly deal with iHerb.com again. Thank you for your excellent service. Doug Hodgins

It is hard to say what it does... I feel something for sure.... maybe I feel a bit more concentrated and focused as well as in some in instances I think I have a small improvement with memory. Will see :)
