Alpha GPC, or L-alpha-glycerylphosphorylcholine, is a highly bioavailable choline-containing compound used in nutritional and neurological research. A 50% extract provides approximately half its weight as Alpha GPC, making the standardized concentration important when determining the actual active amount.

Product Information

Alpha GPC supplies choline for acetylcholine synthesis and can cross the blood-brain barrier. Research has investigated it for cognitive function, neurological conditions, and exercise-related effects, while recent reviews continue to evaluate its broader biological activity.

How It Works

Alpha GPC increases the availability of choline, which can then be used to produce acetylcholine. Because acetylcholine plays major roles in memory, attention, learning, and neuromuscular signaling, Alpha GPC has attracted interest across cognitive and performance research.

POTENTIAL BENEFITS

1. Supports Choline Availability

Alpha GPC is a concentrated source of choline and is readily utilized by the body. Its ability to provide choline to the nervous system is central to its cognitive and neurological research profile.

2. Supports Acetylcholine Production

Choline supplied by Alpha GPC serves as a precursor for acetylcholine, an important neurotransmitter involved in memory, attention, learning, and muscle signaling.

3. Cognitive Function Research

Clinical research has investigated Alpha GPC in people with cognitive impairment, while meta-analytic evidence suggests potential benefits in certain adult-onset cognitive disorders.

4. Motivation and Mental Performance

Human research has also examined Alpha GPC's influence on motivation and subjective mental states, adding another dimension to its cognitive-performance profile.

Dosage

Human research has used Alpha GPC at various doses depending on the application. Historical clinical research included 400 mg three times daily orally, while more recent supplementation research has used lower amounts. For a 50% extract, the amount of extract required to provide a particular Alpha GPC dose will depend on the product's standardized content.

Side Effects

Alpha GPC is generally well tolerated in studied populations, although possible adverse effects include headache, dizziness, gastrointestinal discomfort, and insomnia. Excessive cholinergic activity may also cause symptoms such as sweating or gastrointestinal upset.
