Alpha-GPC and Citicoline
Both are bioavailable choline sources that raise acetylcholine; alpha-GPC delivers more choline by weight while citicoline also provides cytidine for membrane synthesis.
Alpha-GPC
A highly bioavailable choline source for memory and power output.
Citicoline
A choline source studied for focus, memory, and brain health.
Great to combine
These two are frequently stacked together; they complement each other and are commonly taken at the same time.
How to take them
Alpha-GPC
- Dose
- 300–600 mg per day (often 300 mg pre-workout)
- Timing
- With or without food; pre-workout for power output or in the morning for focus
Citicoline
- Dose
- 250–500 mg per day (up to 2,000 mg in clinical studies)
- Timing
- In the morning or early afternoon, with or without food
Frequently asked
Can you take Alpha-GPC and Citicoline together?
Yes, they are commonly taken together. Both are bioavailable choline sources that raise acetylcholine; alpha-GPC delivers more choline by weight while citicoline also provides cytidine for membrane synthesis.
What's the best time to take Alpha-GPC and Citicoline?
Around the same time works well. Alpha-GPC: With or without food; pre-workout for power output or in the morning for focus. Citicoline: In the morning or early afternoon, with or without food.
How do Alpha-GPC and Citicoline interact?
Synergy: Work better together than alone. Both are bioavailable choline sources that raise acetylcholine; alpha-GPC delivers more choline by weight while citicoline also provides cytidine for membrane synthesis.
Related pairings
Alpha-GPC + Caffeine
Commonly paired pre-workout and in focus stacks; alpha-GPC supports power output and acetylcholine while caffeine adds stimulation.
Alpha-GPC + Huperzine A
A classic cholinergic stack: alpha-GPC supplies the choline to build acetylcholine while huperzine A slows its breakdown.
Alpha-GPC + Phosphatidylserine (PS)
Both supply phospholipid and choline building blocks that support membranes and cholinergic signaling for cognition.
Alpha-GPC + L-Tyrosine
Often combined in focus formulas, pairing a choline source with a dopamine precursor for attention under demand.
