Alpha-GPC (L-Alpha Glycerylphosphorylcholine)
HIGH 100Choline form that crosses the blood-brain barrier efficiently
Best for:Cognitive performancePower output (athletic)Acetylcholine boost
💡 Excellent. ~40% choline by weight; raises plasma + brain choline rapidly.
✅ Pros
- • Crosses BBB
- • Cognitive performance data
- • Strength/power data
⚠️ Cons
- • Expensive
- • Can be stimulating (avoid evening)
📝 Best for cognitive and athletic use. 300-600 mg/day typical.
CDP-Choline (Citicoline)
HIGH 95Cytidine-5'-diphosphocholine — provides choline plus cytidine (uridine precursor)
Best for:Memory and focusStroke recovery (medical)ADHD support
💡 Excellent. Yields both choline and uridine, supporting membrane phospholipid synthesis.
✅ Pros
- • Strong cognitive data
- • Cognizin® form well-researched
- • Good tolerability
⚠️ Cons
- • Expensive
- • Lower choline per mg than Alpha-GPC
📝 Best evidence for memory and focus. Cognizin is the studied branded form.
Phosphatidylcholine (Lecithin)
GOOD 75Phospholipid form found in egg yolks and soy lecithin
Best for:Liver supportGeneral choline statusMembrane health
💡 Good. ~13% choline by weight; supports liver-specific choline pools.
✅ Pros
- • Liver-friendly
- • Whole-food form
- • Less likely to cause TMAO concerns
⚠️ Cons
- • Lower choline per dose
- • Bulky pills/granules
📝 Good for liver/fatty liver focus. Sunflower-derived lecithin avoids soy concerns.
Choline Bitartrate
LOW 55Salt form, commonly used in budget supplements
Best for:Basic deficiency correctionCost-effective bulk supplementation
💡 Moderate. ~41% choline by weight but limited brain penetration.
✅ Pros
- • Cheap
- • Decent for basic intake
⚠️ Cons
- • Doesn't readily cross BBB
- • Fishy body odor at higher doses (TMA conversion)
- • No cognitive enhancement
📝 Fine for hitting AI (550 mg/day), poor for nootropic effect. Use Alpha-GPC or CDP for brain effects.
