This is **Cognizin** citicoline — the branded form behind most human cognition trials — at a full 500mg daily serving, the top of the studied range for memory, attention, and focus. Citicoline (CDP-choline) is one of the few choline forms that crosses into the brain, where it fuels acetylcholine production and raises uridine, both linked to sharper cognition. As directed, you're getting a genuine brain-active dose, not a token amount.
At 500mg you're in studied territory for focus and mental energy, not just topping up general choline needs. Citicoline's cognitive benefits in the research come from this brain-active form specifically, which is why both the dose and the form matter here.
Each serving is two capsules, so the 500mg splits to 250mg per capsule — if you take only one, you're still in a studied range but at the lighter end used for everyday cognitive support rather than the fuller 500mg dose.
