Alpha-GPC 50% Capsules are also available.
Alpha-GPC is a phospholipid metabolite and precursor to phosphatidylcholine and acetylcholine. ??Alpha-GPC is considered one of the best choline supplements available as it only requires 46% of the dose of CDP-choline to achieve similar effects.  It is found in foods such as beef liver, oat bran, Atlantic cod, and milk ??? though not at levels high enough to be useful ??? so additional supplementation is worthwhile. 
Alpha-GPC supplements general cognition.  Supplementing with Alpha-GPC promotes the translocation and activation of protein kinase C (PKC), which is responsible for short and long-term memory.* 
Alpha-GPC also supplements learning, thinking, and memorization.  Again, the translocation and activation of protein kinase C play??a role in these benefits.  Phosphatidylserine, when taken with Alpha-GPC, can be synergistic in aiding the supplementation of cognition.* 
Alpha-GPC also benefits body composition and power output during exercise.* [9,10]

Why just 50%?
Alpha-gpc is a hygroscopic supplement, meaning it absorbs water with ease. When water is absorbed the supplement can clump or turn into a paste making supplementing difficult. You will also see some companies using dicalcium phosphate with their alpha-gpc for these purposes. Silicon dioxide has a much better absorption rate which allows for the product to have a greater shelf life.
Silicon dioxide is not water soluble so only the alpha-gpc will dissolve when mixing in a beverage.
What if this supplement doesn?۪t work for me?
“I’m new to nootropics and Powder City, and I’m still learning the right combinations for me. First of all, Powder City has been a great company to order merchandise from my initial order, through the tracking of merchandise sent to my e-mail to keep tabs on it, and ultimately receiving my purchase in excellent condition, on time, and the product itself worthy of my review/time here. Alpha-GPC 50 has worked well for me. I noticed better concentration and a heightened ability to recall information on demand within an hour or two after consumption. In my profession I have to have the utmost concentration and information/memory available instantaneously with absolute accuracy. So when I experience “it” as I have, then I know this is a good product. Of course I’ve combined Alpha-GPC with other nootropics, but this is the one I keep using consistently with different variations, so it’s a star for me. I highly recommend Powder City for the quality of their product(s), prices, and service. Thank you and I have shared your company information with others.”– Rabbit
