Benefits And Science

A trial added citicoline 2500 mg to risperidone and negative symptoms improved. A 2025 network meta-analysis puts the effect on total symptoms.

One small trial found citicoline helped citalopram work better. The largest network meta-analysis flagged citicoline for significantly more dropouts.

A 60-person trial gave citicoline 2000 mg daily to people with depression and methamphetamine dependence. Mood improved. Drug use did not.

Five randomized trials tested citicoline in cocaine dependence. The two positive ones were in patients with bipolar disorder, and the effect faded.

Citicoline acts on the same nicotinic receptors nicotine does. No human study has tested whether it helps anyone quit smoking or vaping.

Two randomized trials tested IV citicoline in newborns with brain injury from oxygen loss. Both enrolled babies who could not receive cooling.

A single 80-child trial reported better outcomes with IV citicoline after cardiac arrest. It had no placebo arm, one site, and no replication.

Every citicoline spinal cord injury study is a rat or a dish. None used an oral capsule, and the closest motor neuron model showed nothing at all.

No trial has tested oral citicoline capsules for diabetic nerve pain. The human data is eye drops and injections combined with a second drug. Here is why.

The one double-blind placebo-controlled trial of citicoline in vascular dementia ran 12 months and found nothing. The positive studies were open-label.

A 2025 randomized trial gave citicoline to 101 autistic children for two months and found no benefit on any measured scale. Here is what it tested.

CDP-choline has a real cluster of human EEG gating studies. Effects showed up only in people who started with poor gating, and only in brain signals.
