Dyslipidemia is an abnormal amount of fats in the blood (usually cholesterol and triglycerides). Recent research, appearing in the Saudi Journal of Kidney Diseases and Transplantation (2012 May; 23(3):484-8) looked at the effect supplementation with L-carnitine had on the lipid profiles of dialysis patients. Thirty subjects received 250 mg of L-carnitine for eight weeks; 30 other patients were used as a control and not given the supplement. Serum lipid profiles were compared at baseline and after intervention. Values of the lipid profile in the intervention group decreased, including LDL and total cholesterol, but not HDL after L-carnitine supplementation.
