Across 3 studies, 2 reported beneficial effects of acetyl-carnitine on neuropathic pain, with moderate effect sizes in clinical populations. One systematic review found neutral results for magnesium and St. John's wort but did not specifically isolate acetyl-carnitine effects. The median study duration was 56 days, suggesting effects may be observed at around 8 weeks. No consistent dose or form was identified across studies.
- Studied populations: patients with acute low back trauma; patients with peripheral neuropathies
Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. One systematic review (2024) that found neutral effects did not appear to isolate acetyl-carnitine as a primary intervention, instead grouping it with other supplements for mixed neuropathologies. Both beneficial studies are recent and may reflect emerging but unconfirmed findings.
