A precursor to NAD+, a coenzyme involved in cellular energy production and metabolic processes throughout the body.*
A plant-derived polyphenol studied for its antioxidant activity and involvement in cellular stress-response pathways.*
A carotenoid that accumulates in the macula of the eye and contributes to macular pigment, which filters some blue light.*

Clinician reviews
Specialty in Internal Medicine
Citicoline (CDP-Choline) is an interesting ingredient for brain health because it helps support the production of phospholipids, which are essential for maintaining healthy brain cell membranes. It also contributes to pathways involved in acetylcholine production, a neurotransmitter important for memory, learning, and attention.*
