This **citicoline** delivers a full 500mg dose for memory, focus, and brain support — the top of the clinically studied range (250–500mg/day) for cognition and attention. You're getting it as CDP-choline, a form that crosses into the brain, where it supports acetylcholine production and helps maintain healthy brain cell membranes.
Two capsules deliver the complete 500mg, so following the label's daily serving lands you right where the research is — there's no need to stack extra servings. A small 30mg of choline bitartrate comes along for general choline needs, but the citicoline is what's driving the cognitive benefit.
The one thing to know is that the effective dose lives in the full 2-capsule serving. Split it to one capsule and you're at 250mg — the floor of the studied range rather than the full benefit.
