This December 2016 Australian review published in September 2017 concerned:
“..the nutritional psychiatry field..the neurobiological mechanisms likely modulated by diet, the use of dietary and nutraceutical interventions in mental disorders, and recommendations for further research.”
The reviewers inexplicably omitted acetyl-L-carnitine, which I first covered in A common dietary supplement that has rapid and lasting antidepressant effects. A PubMed search on “acetyl carnitine” showed over a dozen studies from the past twelve months that were relevant to the review’s subject areas. Here’s a sample, beginning with follow-on research published in June 2016 of the study I linked above:
The cited references in these recent studies were older, of course, and in the time scope of the review. There’s no excuse for this review’s omission of acetyl-L-carnitine.
