What it's actually good for

Focus

Research Supported

Human trials show improvements in attention and focus, particularly in women and adolescents.

Longevity

Mixed Evidence

Evidence for slowing age-related cognitive decline is promising but requires long-term use.

Mood

Weak Evidence

Some reports of mood enhancement exist, but community data often notes 'choline depression' at high doses.

How it works

Citicoline is a brain-health nutrient that provides both choline and cytidine, which converts to uridine in humans. Clinical evidence supports its use for improving memory and attention in older adults with age-associated memory impairment, though results in acute stroke and healthy young populations are mixed or limited.

It acts as an intermediate in the synthesis of phosphatidylcholine, a major structural component of neural membranes, and serves as a precursor for the neurotransmitter acetylcholine.

Safety

Generally well-tolerated with a low incidence of side effects.
May cause mild gastrointestinal upset, headache, or insomnia in sensitive individuals.
Potential minor interaction with levodopa; consult a physician if treating Parkinson's.
