Alpha-GPC (Alpha-glycerophosphocholine or in some cases just glycerophosphocholine) is a choline- including supplement that, although found in a variety of foodstuff that are also abundant in choline, appears to be pharmacologically active at greater doses. Alpha-GPC is mostly marketed due to it giving dietary choline to the body following oral ingestion, and being the most effective choline prodrug at doing so (able to affect both systemic and brain concentrations of choline).
Oral supplementation of alpha-GPC is of interest for nootropic purposes, as it appears to have cognitive-enhancing homes (no human evidence exists to support this in otherwise-healthy youth, but it does have assistance in rodents) and attenuate the rate of cognitive decline in the senior. In concerns to lowering the rate of cognitive decrease, alpha-GPC at high dosages (1,200 mg) does seem rather efficient in moderate to moderate Alzheimer's illness and works nicely with the basic treatment (acetylcholinesterase inhibitors).
The loss of neurons that use the neurotransmitter acetylcholine is an early occasion in the development of Alzheimer's illness . Nevertheless, no studies have actually taken a look at whether alpha-GPC improves cognition in healthy people or avoids Alzheimer's illness. In one open-label research study, clients with mild cognitive disability reported that alpha-GPC treatment slightly improved cognition over 90 days, and this impact appeared to be more noticable in patients without APOE4, the genetic danger element for Alzheimer's disease .See more at Alpha GPC Benefits
Alpha GPC More Information
Preclinical studies suggest that alpha-GPC increases the levels of acetylcholine in the brain and can improve cognition in designs of memory disability or brain aging [3; 4]. In a model of sped up aging, alpha-GPC had no impact on brain levels of beta-amyloid, a biological marker of Alzheimer's disease . Nevertheless, in a design of hypertension, alpha-GPC lowered swelling around capillary in the brain, although it did not maintain the integrity of brain capillary.

One research study reported that alpha-GPC improved cognition and function in patients with moderate to moderate dementia over six months. Nevertheless, the patients were not taking presently approved Alzheimer's drugs which also increase levels of acetylcholine in the brain .
