This guide explains citicoline (CDP-choline) and commonly asked related supplements in a clear, evidence-informed way: what it is, how it may work, safety, who should avoid it, and how nutrition supports the same pathways.\n\nDisclaimer: This is not medical advice. If you are pregnant, breastfeeding, have chronic disease, use regular medication, or have neuro/psychiatric conditions, consult a clinician before starting supplements.
