What is Citicoline?
Citicoline (also known as CDP-choline or cytidine diphosphate-choline) is a naturally occurring molecule that is composed of two parts: cytidine and choline. Cytidine is a nucleoside that can be converted into uridine in the body. Uridine is a precursor for RNA synthesis and phosphatidylcholine production. Phosphatidylcholine is a major component of cell membranes and neurotransmitter vesicles.
Choline is an essential nutrient that can be obtained from food or synthesized in the body from phosphatidylcholine or other sources. Choline is involved in many biological processes, such as methylation reactions, acetylcholine synthesis, and phospholipid metabolism. Acetylcholine is a neurotransmitter that is responsible for memory, learning, attention, and arousal.
Citicoline was first discovered in 1956 by Italian scientists who isolated it from the brain of animals. Since then, citicoline has been extensively studied and used as a therapeutic agent for various neurological and psychiatric conditions. Citicoline is available as a dietary supplement in many countries, and as a prescription drug in some countries, such as Japan, Italy, and Spain.
How Does Citicoline Work?
Citicoline works by increasing the levels of cytidine, uridine, choline, and acetylcholine in the brain. These substances have multiple effects on the brain, such as:
Enhancing cognitive performance: Citicoline can improve various aspects of cognition, such as memory, attention, executive function, and processing speed. This is mainly due to the increased availability of acetylcholine, which modulates synaptic plasticity and neuronal communication. Citicoline can also increase the levels of dopamine and norepinephrine, which are involved in motivation, reward, and arousal.
Protecting neurons from damage: Citicoline can protect the brain from oxidative stress, inflammation, ischemia, and excitotoxicity. These are common causes of neuronal death and dysfunction in many neurological disorders. Citicoline can reduce the production of free radicals, inhibit the activation of inflammatory cells and cytokines, increase the blood flow and oxygen supply to the brain, and regulate the glutamate receptors and calcium influx.
Promoting neurogenesis: Citicoline can stimulate the growth and differentiation of new neurons and synapses in the brain. This is especially important for the recovery and regeneration of damaged brain tissue. Citicoline can increase the expression of neurotrophic factors, such as brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), which support the survival and maturation of neural cells.
What are the Benefits of Citicoline?
Citicoline has been shown to have beneficial effects for various neurological and psychiatric conditions, such as:
Stroke: Citicoline can reduce the size of the infarct area, improve the neurological outcome, and enhance the functional recovery after ischemic stroke. Citicoline can also prevent or delay the onset of post-stroke cognitive impairment and dementia.
Traumatic brain injury: Citicoline can improve the cognitive and behavioral symptoms, reduce the intracranial pressure and edema, and promote the structural repair after traumatic brain injury.
Alzheimer's disease: Citicoline can slow down the progression of cognitive decline, improve the memory and attention performance, and increase the cerebral metabolism in patients with mild to moderate Alzheimer's disease.
Parkinson's disease: Citicoline can improve the motor function, reduce the levodopa-induced dyskinesia, and increase the dopamine levels in patients with Parkinson's disease.
Depression: Citicoline can augment the antidepressant effect of selective serotonin reuptake inhibitors (SSRIs), improve the mood and cognitive function, and modulate the serotonin and dopamine systems in patients with major depressive disorder.
Schizophrenia: Citicoline can enhance the antipsychotic effect of conventional drugs, improve the positive and negative symptoms, and ameliorate the cognitive impairment in patients with schizophrenia.
What are the Side Effects of Citicoline?
Citicoline is generally well tolerated and safe when used at recommended doses. However, some people may experience some mild to moderate side effects, such as:
These side effects are usually transient and resolve on their own or with dose adjustment. However, if they persist or worsen, you should consult your doctor or pharmacist.
Citicoline may also interact with some medications or supplements that affect the cholinergic or dopaminergic systems. For example:
Anticholinergic drugs (such as atropine, scopolamine, benztropine) may reduce the effectiveness of citicoline by blocking its action on acetylcholine receptors.
Cholinergic drugs (such as donepezil, rivastigmine, galantamine) may enhance or synergize with citicoline by increasing its action on acetylcholine receptors.
Antidepressant drugs (such as fluoxetine, sertraline, bupropion) may interact with citicoline by affecting its action on serotonin and dopamine receptors.
Therefore, you should inform your doctor or pharmacist if you are taking any medications or supplements before using citicoline. You should also follow their instructions on the dosage and timing of citicoline to avoid any potential interactions or adverse effects.

Now that you have learned more about citicoline and its effects on the brain, you may be interested in reading a recent drug study on citicoline that was published in a peer-reviewed journal and is available for free online. The study is titled "Citicoline Improves Cognitive Performance in Healthy Older Adults: A Randomized, Double-Blind, Placebo-Controlled Trial" and was conducted by researchers from the University of Utah and the University of California, Irvine.
In this section, we will review the purpose, design, results, limitations, and implications of the study. We will also provide you with a link to download the full-text pdf of the study for free.
What was the Purpose of the Study?
The purpose of the study was to investigate the effect of citicoline on cognitive performance in healthy older adults. The researchers hypothesized that citicoline would improve cognitive performance in domains such as memory, attention, executive function, and processing speed. They also hypothesized that citicoline would increase the levels of phosphatidylcholine and acetylcholine in the brain.
What was the Design of the Study?
The study was a randomized, double-blind, placebo-controlled trial. This means that the participants were randomly assigned to either receive citicoline or a placebo (a dummy pill), and neither the participants nor the researchers knew who received what until the end of the study. This design reduces the risk of bias and confounding factors.
The study involved 60 healthy older adults aged 50 to 85 years who had no history of neurological or psychiatric disorders. The participants were divided into two groups: one group received 500 mg of citicoline twice a day for 12 weeks (total daily dose of 1000 mg), and the other group received a matching placebo twice a day for 12 weeks.
The participants underwent a series of cognitive tests before and after the intervention. The tests measured various aspects of cognition, such as verbal memory, visual memory, attention, executive function, and processing speed. The participants also provided blood samples before and after the intervention to measure the levels of phosphatidylcholine and acetylcholine in their plasma.
The researchers used various statistical methods to analyze the data and compare the differences between the groups.
What were the Results of the Study?
The results of the study showed that citicoline significantly improved cognitive performance in healthy older adults compared to placebo. Specifically, citicoline improved verbal memory (measured by Rey Auditory Verbal Learning Test), visual memory (measured by Brief Visuospatial Memory Test), attention (measured by Stroop Color-Word Test), executive function (measured by Trail Making Test), and processing speed (measured by Digit Symbol Substitution Test).
The results also showed that citicoline significantly increased the levels of phosphatidylcholine and acetylcholine in plasma compared to placebo. This suggests that citicoline enhanced the synthesis and availability of these substances in the brain.
The results were consistent across different age groups, genders, and education levels. The effect sizes were moderate to large, indicating that citicoline had a clinically meaningful impact on cognitive performance. The significance levels were below 0.05, indicating that the results were unlikely to be due to chance. The confidence intervals were narrow, indicating that the results were precise and reliable.
What were the Limitations of the Study?
The study had some limitations that should be considered when interpreting its results. For example:
The sample size was relatively small (60 participants), which may limit the statistical power and generalizability of the results.
The duration of the intervention was relatively short (12 weeks), which may not reflect the long-term effects of citicoline on cognitive performance.
The cognitive tests used in the study may not capture all aspects of cognition, such as creativity, problem-solving, or social cognition.
The study did not measure the levels of citicoline or its metabolites in the brain, which may provide more direct evidence of its mechanisms of action.
The study did not include a follow-up assessment to evaluate the persistence or decay of the effects of citicoline after the intervention.
What were the Implications of the Study?
The study had some implications that should be considered when applying its results. For example:
The study provided evidence that citicoline can improve cognitive performance in healthy older adults, which may have implications for preventing or delaying cognitive decline and dementia.
The study suggested that citicoline can increase the levels of phosphatidylcholine and acetylcholine in the brain, which may have implications for enhancing synaptic plasticity and neuronal communication.
The study indicated that citicoline can be used as a safe and effective dietary supplement for improving brain health and function, which may have implications for personal and public health.
The study encouraged further research on citicoline and its effects on cognition, which may have implications for advancing the scientific knowledge and clinical practice in the field of neuroscience and psychology.
