About Choline
Essential for acetylcholine synthesis, cell membrane integrity, and methylation reactions supporting liver and brain function. Alpha-GPC and CDP-choline (citicoline) are superior supplemental forms that cross the blood-brain barrier effectively—Alpha-GPC for cognitive support and physical performance, CDP-choline for sustained neuroprotection and dopamine support. Basic choline bitartrate has lower brain penetration but is sufficient for general needs.
What Choline supports
- Enhances memory and cognition
- Supports liver function
- Enables muscle movement
How much Choline to take
Clinical studies typically use 100–500 mg of Choline. Supplemental range; typical choline supplements provide 250-500mg. 100mg is minimum meaningful contribution.
- RDA
- 550 mg
- Upper limit (UL)
- 3500 mg
- Effective range
- 100–500 mg
Forms of Choline compared
- Alpha-GPCPremiumHighest brain bioavailability; clinically dosed at 300–600 mg for cognition.
- CDP-choline (Citicoline)PremiumCiticoline (Cognizin); raises both choline and uridine — RCT-supported for cognition.
- PhosphatidylcholineStandardMembrane phospholipid form; ~13% choline by weight, slow but steady absorption.
- LecithinBudgetMixed phospholipids with ~13% phosphatidylcholine; the cheapest source by elemental choline.
- Choline bitartrateBudgetCheap multivitamin form — barely raises plasma choline at typical label doses.
- Choline chlorideBudgetStandard salt form; lower brain uptake than Alpha-GPC or CDP-choline.
Clinical evidence
Strong clinical evidence. Essential for acetylcholine synthesis and cell membranes; Alpha-GPC and CDP-choline cross blood-brain barrier
