The document discusses the benefits of L-carnitine supplementation. L-carnitine is an amino acid that transports fat into cells for energy production. Taking L-carnitine supplements can increase fat burning, enhance physical performance, reduce muscle soreness, and boost recovery from intense exercise by promoting the use of fat over carbohydrates. Regular L-carnitine intake also increases insulin sensitivity, supports male fertility, and may reduce the risk of metabolic diseases like diabetes. The producer of Paleo Protein supplements has added L-carnitine due to these health benefits.
