Citicoline is a compound your body makes to help keep brain cell membranes intact and support production of key neurotransmitters. People take it to sharpen focus, mental clarity, memory, and attention during intense work.
Typical use involves split doses, with or without food. Taking it alongside a meal may help absorption. Headache or stomach upset can show up, though side effects are uncommon.
If you are pregnant, nursing, or taking any medications, check with a healthcare provider before use.
