L-Carnitine and Increased Serum Albumin Levels

Research synthesisModerate evidenceMixed effect size3 studies · 3 beneficial · 0 neutral · 0 harmful

Across 3 studies, all reported beneficial effects on serum albumin levels, with effect sizes ranging from small to large (small, moderate, large). The most studied dose was 3 g/day in critically ill patients (sepsis, ICU, hemodialysis). Effects were observed over short durations (median 7 days).

  • Effective dose range: approximately 3 g/day
  • Studied populations: critically ill patients (sepsis, ICU, hemodialysis)

Caveats: Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Effect size varied across studies (small to large). Studies were short-term (median 7 days), so long-term effects are unknown.
