Citicoline (CDP-Choline)

Premium fuel for your brain — feeds the chemicals that power thinking

01 — OVERVIEW
SYSTEMSHow Citicoline (CDP-Choline) affects you

Fuels focus with brain choline.

Breaks down into choline and cytidine. Choline builds acetylcholine (the focus neurotransmitter); cytidine converts to uridine, which supports synaptic membranes.

Acetylcholine
downstream
  • Studied in stroke recovery, age-related cognitive decline, and ADHD.
  • Gentler than alpha-GPC — less intense but also rarely causes brain fog.
  • Also called CDP-choline in the literature.

Your brain needs specific chemicals to think, learn, and remember. The most important one is called acetylcholine — think of it as your brain's 'thinking fuel.' Citicoline gives your brain the raw ingredients to make more of this fuel. It also helps build stronger brain cell walls, so signals travel faster and cleaner. Studies show it boosts brain energy by over 13%. It's basically premium gas for your brain.

  • Rare headache (usually means your dose is too high)
  • Can't sleep if you take it too late
  • Mild stomach discomfort
05 — WARNINGS

Before you start.

  • Very safe — tons of clinical studies backing it up
  • If you get headaches, your brain might already have enough — just lower the dose
  • Works just as well long-term — no tolerance issues
06 — STACKING & INTERACTIONS

Combinations worth knowing.

Brain Builder Stack

Citicoline gives your brain the building materials while Lion's Mane tells it to start building. Together, they're like hiring a construction crew AND buying the supplies.
