    Phosphatidylcholine for Liver Protection

    Phosphatidylcholine supports liver health by supplying the choline and phospholipid substrate needed to export liver fat; the best evidence is for choline-deficiency fatty liver, with mixed results in established liver disease.

    Overview

    Phosphatidylcholine supports liver health by supplying the choline and phospholipid substrate needed to export liver fat; the best evidence is for choline-deficiency fatty liver, with mixed results in established liver disease.

    Verdict

    Mixed evidence

    Sensible for people with low choline intake or documented deficiency; benefits in established liver disease are unproven.

    How It Works

    PC is required to assemble VLDL particles that export triglycerides from hepatocytes; deficiency traps fat in the liver. Purified PPC also integrates into hepatocyte membranes, reducing oxidative damage in preclinical models.

    Dosing & Protocol

    Typical dose

    Recommended dose
    900-1,800 mg/day polyenylphosphatidylcholine in divided doses with meals; hepatology trials used up to 1,800 mg/day
    Expected timeframe
    8-12 weeks for ALT changes; fatty liver imaging changes take months.

    Protocol

    form
    Purified PPC or lecithin
    duration
    12+ weeks; reassess liver enzymes
    titration
    Up to 1.8-2.7g PPC daily in liver trials
    starting dose
    500mg PC twice daily with meals

    Evidence

    What the studies say

    Controlled feeding studies prove choline deficiency causes fatty liver, reversible with repletion — and PC is an effective choline source. Trials of PPC in alcoholic liver disease showed slowed fibrosis progression in some analyses but no mortality benefit. Evidence in NAFLD is thinner: small trials suggest ALT improvements, but no large randomized trials exist.

    Safety

    Caveats

    {"Not a treatment for viral hepatitis or advanced disease","Diet quality and alcohol reduction dominate any supplement effect"}

    Less likely to help if

    {"People with adequate dietary choline unlikely to notice a difference"}
