Depression linked to low blood levels of acetyl-L-carnitine

Depression linked to low blood levels of acetyl-L-carnitine Depression linked to low blood levels of acetyl-L-carnitine In the latest study, the scientists measured levels of LAC (acetyl-L-carnitine) in blood samples taken from people diagnosed with MDD. They found that levels were significantly decreased in these patients, as compared to age-matched individuals without depression. Additional analysis…
