Citicoline is a naturally occurring compound in the body that plays a crucial role in brain health. It is a source of choline, which is essential for the production of acetylcholine, a neurotransmitter involved in memory and learning. Citicoline is often used as a dietary supplement to support cognitive function and may help in conditions like Alzheimer's disease and stroke recovery. As a supplement, citicoline is believed to enhance brain energy metabolism and promote the repair of neuronal membranes. It is generally considered safe, with few reported side effects. Some studies suggest that it may improve attention, focus, and overall mental performance.
