Alpha-GPC (alpha-glycerophosphocholine, choline alfoscerate) is a water-soluble nutrient which serves as a precursor to both choline and glycerophosphate within the brain.
Alpha GPC benefits range from an increase in memory, learning capacity, attention span, and focus to more mental energy and even mood enhancement.
Athletes have been known to use alpha-GPC due to its purported ability to enhance growth hormone production and to enhance power output (which is based on a lone pilot study in support of subjects ingesting 600 mg alpha-GPC prior to exercise.
 
Cognitive effects
Wakefulness
Wakefulness can be described as an increased ability to stay conscious without feeling tired combined with a decreased need to sleep. It is contrasted with stimulation in that it does not directly increase one's energy levels above a normal baseline but instead produces feelings of a wakeful, well-rested and alert state.
In comparison to citicoline, alpha-GPC manifests itself primarily in a physically stimulating manner over a mental stimulation.
Dream potentiation
Dream potentiation can be described as a cognitive component which increases the intensity, vividness and frequency of sleeping dream states. This effect also results in dreams having a higher level of detail and definition alongside a greatly increased likelihood of them becoming lucid.
Focus enhancement
Focus enhancement can be described as the experience of an increased ability to selectively concentrate on an aspect of the environment while ignoring other things. It can be best characterized by feelings of intense concentration which can allow one to focus on and perform tasks which would otherwise be considered too monotonous, boring, or dull to not get distracted from. This will often synergize with other coinciding effects such as motivation enhancement, thought acceleration, and stimulation.
Memory enhancement
Memory enhancement can be described as an effect which results in an improved ability to recall and retain memories. The experience of this effect can make it significantly easier for a person to access past memories and recall them at a greater level of detail compared to their sober state. It can also help one retain new information that may then be more easily recalled once the person is no longer under the influence of the substance.
Motivation enhancement
Motivation enhancement can be described as an increased desire to perform tasks and accomplish goals in a productive manner. It can be best characterized as an increased desire to perform tasks, including those that would normally be considered too monotonous or overwhelming to fully commit oneself to.
This effect will often synergize with other coinciding effects such as focus enhancement, thought acceleration, and stimulation in a manner which further increases one's productivity.
