Alpha GPC

Nootropics

Key Benefits

Most bioavailable choline source for brain
Rapid acetylcholine elevation
Growth hormone secretion
Cognitive enhancement

How It Works

Alpha-glycerophosphocholine crosses the blood-brain barrier efficiently, releasing choline for acetylcholine synthesis and glycerophosphate for phospholipid membrane repair. It's the most efficient choline source for brain levels. Also stimulates growth hormone release acutely.

Dosage & Timing

Recommended Dosage

300-600 mg daily (up to 1,200 mg)

Best Time to Take

Morning or pre-workout for cognitive enhancement

Recommended Form

Alpha GPC 50% (standard potency) capsules

Side Effects

Generally well-tolerated. Headaches, dizziness, GI discomfort rarely. Very high chronic doses may have cardiovascular concerns.

Drug Interactions

May enhance effects of anticholinergic and cholinergic drugs. Consider stroke risk at very high chronic doses (recent research).

What Does The Research Say?

Studies show cognitive benefits in Alzheimer's (1,200mg/day), enhanced power output in athletes, and increased growth hormone. The most efficient way to raise brain acetylcholine. Recent observational study raised stroke concerns at high chronic doses.
