- Moderate evidence3 studies
Across 3 studies, all reported beneficial effects of L-carnitine on increasing serum total protein levels, with effect sizes ranging from moderate to large. The evidence includes a recent RCT in ICU patients (3 g/day for 7 days) and a meta‑analysis in hemodialysis patients, where the pooled total protein increase was large (3.83 g/dL, p = 0.000). The median study duration was 186 days, but effects were seen even after one week. The most studied populations are clinical patients with renal insufficiency or critical illness.
