Citicoline has been studied for decades, including specific forms such as Cognizin, which has been examined in several clinical studies. Here are five potential benefits research has identified.
1. Retinal Support
Citicoline has been shown to support the dopaminergic system in both the brain and the retina. The retina is closely connected to the central nervous system and depends on healthy cells, strong energy production, and proper neurotransmitter function.
Research suggests that citicoline may help restore low dopamine levels in the retina and slow myopic shift (worsening nearsightedness). Because of this, it is being studied as a possible option for myopia control, especially in younger people who spend long hours on screens or doing near work.
For glaucoma, the research is stronger. Citicoline acts as a neuroprotector, helping protect nerve cells in people with glaucoma, even when eye pressure is already controlled. Studies suggest it may be a useful addition to standard glaucoma treatments, although more research is still needed for conditions like amblyopia and myopia.
Some studies also found that citicoline helped restore optic nerve signals between the eye and brain and reduced vision loss without lowering eye pressure. This suggests it may work differently from traditional glaucoma treatments.
2. Brain Energy Support
Citicoline supports brain energy by helping produce ATP, the main energy source used by cells.
One study found a 13.6% increase in ATP levels in healthy middle-aged adults who took 500 mg of Cognizin daily for six weeks. This suggests citicoline may support brain energy and help maintain healthy brain cell membranes.
Although the brain makes up only about 2% of body weight, it uses around 20% of the body's energy at rest. Supporting brain energy can help maintain mental performance throughout the day.
3. Focus
Research has explored how citicoline may affect attention and focus across different age groups, including adolescents and adults. Several studies have shown improvements in attention after weeks of use, along with increased activity in brain areas tied to focus and cognitive performance.
These effects are thought to be linked to citicoline's role in supporting neurotransmitters like dopamine and acetylcholine, both of which are involved in attention and mental processing. And unlike stimulant-based products, citicoline does not act as a stimulant, meaning it is less likely to cause jitteriness or energy crashes.
4. Memory
Research suggests that taking 500 mg of Cognizin daily may help support memory and reduce age-related memory decline.
Some studies show improvements in memory and thinking, especially in older adults, although more research is still needed to confirm broader benefits.
5. Cell Membrane Support and Neuroprotection
Citicoline provides choline, which helps produce acetylcholine and supports brain cell energy production. It also helps create phosphatidylcholine, an important part of cell membranes throughout the nervous system, including the retina.
When taken as a supplement, citicoline breaks down into choline and cytidine, which are used to rebuild important brain compounds. This process helps protect nerve cells from damage and supports communication between neurons over time.
A Note on Safety
The typical recommended dose of citicoline is 500 mg per day.
People who are pregnant or breastfeeding should avoid citicoline because its safety in these groups is not well known. Always speak with a healthcare professional before starting any supplement.
