L-carnitine plays a crucial role in the transportation of fatty acids into mitochondria, where they are metabolized to produce energy
2013 meta-analysis: A meta-analysis of 13 clinical trials including 3,629 adults with acute myocardial infarction who took L-carnitine (from 2.7 g/day for 5 days to 6 g/day for 12 months) versus placebo found that L-carnitine significantly reduced rates of all-cause mortality, ventricular arrhythmias, and new-onset angina
Although the optimal dose of LC supplementation for myocardial infarction is 3 g/day in terms of all-cause mortality [90], even lower LC intake elevates fasting plasma TMAO [16,17,18, 58, 59], which is ten-fold higher than control after 3 months of supplementation [16, 17]
Some people with ASD also have other health problems, including anxiety and depression, epilepsy, attention deficit hyperactivity disorder (ADHD)
