L Carnitine Is an amino acid that is found in our diet and can also be made by the body. Carnitine can be consumed in our diet from red meats and some levels can be found in fish, poultry and milk products and fewer amounts are available in avocadoes and wheat. Carnitine is primarily stored in the skeletal muscles and heart where it helps to transport fatty acids for muscular activity. It also increases the rate at which the liver oxidizes or uses up fats as an energy generating process and thus is a nutrient that protects us from cardiovascular disease by reducing blood triglycerides and raising the good HDL cholesterol levels. Thus L -carnitine is also a nutrient that is a focus for weight loss and healthy body composition- important for aging and longevity.
