Research indicates moderate evidence for Alpha-GPC's role in improving peak power and cognitive speed in healthy adults and athletes. However, the effects are modest and may not be significant for everyone. Further studies are needed to clarify optimal dosing and long-term effects.
Power output / cognitive speedHealthy adults; athletes · RCTsModerate
Modest but consistent increases in peak power; some cognitive speed improvements.
Enhanced Cognitive Focus
This stack combines acetyl-l-carnitine & alpha-gpc to enhance cognitive performance & focus. Acetyl-l-carnitine supports mitochondrial function & energy production in the brain, while alpha-gpc provides choline, a precursor to acetylcholine, a neurotransmitter involved in memory & learning.
Forms & usage▾
Take 300-600 mg daily, ideally 30-60 minutes before activity.
Safety & trade-offs3▾
Elevated TMAO (cardiovascular risk metabolite) signal from high choline intake — early and debated data
Headache possible at high doses
Context: doses >1200mg
