L-carnitine in pet food is a naturally occurring amino acid derivative that plays a key role in energy production by helping transport fatty acids into cells to be used as fuel.
It can support a healthy metabolism, promote lean muscle mass, aid in fat utilization, and assist in maintaining digestive health. L-carnitine is frequently included in weight management formulations to help pets maintain a healthy weight by optimizing energy use, promoting the breakdown of fat, and supporting overall digestive function.
