Phosphatidylcholine IV
About
About Phosphatidylcholine IV
Intravenous phosphatidylcholine (PC) is a phospholipid essential for cell membrane integrity used in integrative medicine for hepatoprotection, cognitive enhancement, and lipid metabolism support. Originally developed for fatty liver disease treatment (approved in some European countries as Essentiale forte), it is used off-label in optimization medicine for liver regeneration, atherosclerosis, and neurological support. The PC exchange reaction can restore aged cell membranes.
Science
Mechanism of Action
Integrates into cell membranes to restore fluidity and function; provides choline as substrate for acetylcholine synthesis; activates phosphatidylcholine-specific phospholipase to generate second messengers; supports HDL-mediated reverse cholesterol transport and hepatocyte membrane repair.
Dosing
Typical Protocol
250–1,000 mg IV infusion 1–2x per week; often combined with folinic acid in plaquex therapy protocols for cardiovascular support.
