Alpha-GPC 50% Capsules are also available.
Alpha-GPC is a phospholipid metabolite and precursor to phosphatidylcholine and acetylcholine. Â 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 â€” though not at levels high enough to be useful â€” 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 playÂ 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]

For cognitive benefits, take 300mg-600mg (one flat 1.25cc scoop) per day blended with water, sports drink, or encapsulated. On workout days, try ingesting 600mg Alpha-GPC 45-60 minutes before training, to maximize its performance benefiting capabilities.

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 doesnâ€™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
