L-carnitine is an amino acid that plays a crucial role in your body’s energy production, responsible for transporting fatty acids to your cells. We need I-carnitine to be able to keep moving and avoid feeling lethargic, and it’s a key ingredient in most weight loss supplements
. The good news is that our body produces some l-carnitine naturally from the amino acids
lysine and methionine, but for those who aren’t getting enough protein
, or don’t eat animal products, buying an l-carnitine supplement can help support their health and fitness goals.
