Too cheap for clinical trials

Let’s compare and contrast a 2019 meta-analysis and a 2017 review of using acetyl-L-carnitine to treat diabetic neuropathy. A 2019 Brazilian meta-analysis Acetyl‐L‐carnitine for the treatment of diabetic peripheral neuropathy of four previous trials stated: “The risk of bias was high in both trials of different ALC doses and low in the other two trials. … Continue reading Too cheap for clinical trials

A dietary supplement that reversed age-related hearing problems in the brainstem

This 2018 Nevada rodent study was on acetyl-L-carnitine’s action in the brainstem: “We examined age-related changes in the efficiency of synaptic transmission at the calyx of Held, from juvenile adults (1-month old) and late middle-age (18- to 21-month old) mice. The calyx of Held synapse has been exploited as a model for understanding excitation-secretion coupling … Continue reading A dietary supplement that reversed age-related hearing problems in the brainstem

This dietary supplement is better for depression symptoms than placebo

This 2018 Italy/UK meta-analysis subject was the use of dietary supplement acetyl-L-carnitine to treat depression symptoms: “Deficiency of acetyl-L-carnitine (ALC) appears to play a role in the risk of developing depression, indicating dysregulation of fatty acids transport across the inner membrane of mitochondria. However, the data regarding ALC supplementation in humans are limited. We thus … Continue reading This dietary supplement is better for depression symptoms than placebo

A gaping hole in a review of nutritional psychiatry

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 … Continue reading A gaping hole in a review of nutritional psychiatry

Familiar stress opens up an epigenetic window of neural plasticity

This 2015 Italian rodent study found: “There is a window of plasticity that allows familiar and novel experiences to alter anxiety– and depressive-like behaviors, reflected also in electrophysiological changes in the dentate gyrus (DG). A consistent biomarker of mood-related behaviors in DG is reduced type 2 metabotropic glutamate (mGlu2), which regulates the release of glutamate. … Continue reading Familiar stress opens up an epigenetic window of neural plasticity

A common dietary supplement that has rapid and lasting antidepressant effects

This 2012 Italian rodent study found that a common dietary supplement had rapid and lasting antidepressant effects: “Remarkably, L-acetylcarnitine displayed a clear-cut antidepressant effect already after 3 and 7 d[ays] of daily dosing. No tolerance was developed to the action of L-acetylcarnitine. The drug was even more effective after 21 d[ays], and the effect persisted for … Continue reading A common dietary supplement that has rapid and lasting antidepressant effects
