acetyl-l-carnitine pillsNot all patients with unipolar depression respond to the currently available antidepressants. Acetyl-l-carnitine is a compound that enhances mitochondrial function and neuroplasticity and is effective in the treatment of peripheral neuropathy (damage to the peripheral nerves, which sometimes occurs in chemotherapy or diabetes). It is now being investigated as an antidepressant for patients who have not responded to typical antidepressants.

According to a review of the treatment by S.M. Wang et al. published in the Journal of Psychiatric Research in 2014, acetyl-l-carnitine treated depression better than placebo did in four randomized clinical studies. It was better than placebo and equally as effective as the antidepressant fluoxetine and the atypical antipsychotic amisulpride in various studies of dysthymic disorder. It also improved depressive symptoms in people with fibromyalgia and minimal hepatic encephalopathy (liver damage). The usual dose of acetyl-l-carnitine is 1 to 2 grams/day.

Editor’s Note: The role acetyl-l-carnitine will play in treating people with treatment-resistant unipolar or bipolar depression remains to be better clarified.
