This stuff is worth a try for eliminating depression.

Depression Linked With Acetyl-L-Carnitine Deficiency
AUGUST 15, 2018
Gail Connor Roche
Individuals with major depressive disorder (MDD) have low blood levels of the molecule acetyl-L-carnitine (LAC), according to the results of a new study. The research also suggests that the degree of the LAC deficiency reflects the severity and other details about the disorder.
The findings may make LAC a potential biomarker to help in formulating targeted approaches to the diagnosis and treatment of depression, say investigators led by Carla Nasca, PhD, a postdoc fellow at Rockefeller University in New York, New York.
"LAC may aid in identifying a subtype of depression that has greater severity, more likely early life adversity, and may be less likely to respond to standard available antidepressant medications,’’ Nasca told MD Magazine®.
"Surprisingly, the deficiency in LAC is even stronger in patients that don’t respond to standard antidepressants and is linked to a severe, childhood trauma-associated type of depression,” she added. LAC, which is naturally produced in the body, also is available as a dietary supplement. It is broken down in the blood to regulate energy metabolism in the brain.
The study builds on previous research involving mice, which have shown that LAC promotes rapid antidepressant responses in rodent models.
“Rodents with behavioral abnormalities have a LAC deficiency that signals impaired neural and systemic functions such as hippocampal glutamatergic dysfunction, abnormal structural plasticity as well as systemic insulin resistance,” Nasca explained. “These traits are all improved by supplementation with LAC."
To determine if the rodent findings would translate to humans, Nasca, in conjunction with Rockefeller’s Bruce McEwen, PhD, and colleagues at Weill Cornell Medical College, Mount Sinai Medical Center, Stanford University and elsewhere, analyzed data on 116 individuals from 2 independent study centers.
The participants, 45 healthy controls and 71 patients with MDD, were matched for age and sex. Investigators measured LAC levels in the individuals’ blood and found that the levels were decreased in patients with MDD compared with the controls.
A secondary analysis showed that the degree of LAC deficiency reflected both the severity and age of MDD onset. In addition, the investigators found that the decrease in LAC was larger in patients with treatment-resistant depression (TRD). In this group, childhood trauma—specifically a history of emotional neglect and being female—predicted the decreased LAC.
“Models stratified by sex showed emotional neglect as a predictor of LAC concentrations only in women with TRD but not in men,” the authors wrote. There was no interaction with LAC and emotional neglect in the female controls, or in women with non-treatment resistant MDD.
Among the patients with MDD, the team saw no differences in LAC concentrations in relation to the use of psychotropic drugs. In subjects with mild MDD, there was no correlation between LAC levels and the severity of the disease. In contrast, there was ``significant negative correlation” between LAC severity scores: The higher the severity, the lower the concentrations of LAC, the team wrote.
The findings suggest that LAC may serve as a candidate biomarker to help the diagnosis of a clinical endophenotype of MDD, the authors wrote.
"The study is important because it opens the possibility of in the future using a panel of biomarkers to identify and study novel therapeutic targets related to central glutamatergic dysfunction in specific subtypes," Nasca said.
Along with additional research involving rodents, the findings support exploration of LAC as a therapeutic target that might help define individualized treatments in the spirit of precision medicine, the authors said.
“These studies might lead to a new way of thinking about mechanism-based treatments and possible development of future diagnostic tools,” McEwen said.
The study, “Acetyl-l-carnitine deficiency in patients with major depressive disorder,” is published in Proceedings of the National Academy of Sciences of the United States of America.

Thanks! Article is a keeper - may consider a trial, just don't kiss me with my 'fishy' breath side effect  |

The bottle I purchased recommended three capsules per day. I am only taking on an dit seems to be doing the trick.

One a day? What strength? When did you start to notice any difference?

The capsules are 750 mg. I have noticed the depression is gone. it occured over a couple of days.
Only issue I might have is my blood pressure is down a bit so I may need to stop taking my blood pressure medication.

thank you.
this will certainly be worth a try as my anxiety meds don't seem to be working very well since I started on these 2 inhalers. I need positive thoughts running through my head, especially now.
