L-Carnitine May Be Beneficial In Case Of Heart Attack
Researchers at the Mayo Clinic conducted a review of 13 trials and found that L-carnitine (an amino acid found in red meat) may reduce mortality, abnormal heart rhythms, and angina development in a person who is experiencing a heart attack.
This comes on the heels of a recent study conducted by researchers at the Cleveland Clinic that found that L-carnitine may increase the risk of heart disease, stroke, and heart attack.
The 13 trials analyzed included a total of 3629 participants who were over the age of 18. The trials took place between 1973 and 2012 and were culled out of an initial group of 153 that were found during the literature review segment of the analysis.
Compared with placebo, L-carnitine supplementation was associated with a 27% reduction in all-cause mortality, a 40% reduction in angina symptoms, and a 65% reduction in ventricular arrhythmias in individuals experiencing a heart attack.
The study was published in the Mayo Clinic’s own publication online ahead of print on April 15, 2013.
While research on the exact effects of L-carnitine is still evolving, it is important to remember that your body already makes enough L-carnitine for normal functioning and that this study looked specifically at people suffering from heart attack. If you’re worried about too much L-carnitine intake, keep an eye on how much red meat you consume, as well as certain energy drinks and weight loss supplements.
