Do you know that Uridine is a choline enhancer that works with Alpha GPC Choline synergistically to boost memory and overall cognitive function and that taking Alpha GPC and Uridine together works better than each on its own Only Dr. Maxwell provides you with both in a single supplement* Alpha GPC is the most bioavailable form of Choline. Choline sources differ in terms of choline content and absorption. The two most easily absorbed forms are Alpha GPC and CDP Choline, but Alpha GPC has double the choline content of CDP Choline (40.3% vs. 21.4%). PhosphatidylCholine and Choline Citrate have poorer absorption and lower choline content (13.7% and 37.4%), while Choline Bitartrate could lead to kidney and bladder stones* Do you know that it is important to choose soy free Alpha GPC even if you are not allergic to soy Alpha GPC can be derived from lecithin from sunflowers or soy.
