L-carnitine transports fats into the mitochondria where they’re broken down to produce energy. Unless you have a Carnitine Deficiency, your body produces the necessary amount of carnitine to transport fats into the mitochondria and adding more carnitine to your diet is overkill. It neither helps your body decrease fat nor does it aid in weight loss. It might impact your cholesterol, LDL & HDL levels. If you need to use this product you must obtain a prescription from your doctor for the pharmaceutical brand of carnitine.
