Propionyl L-carnitine has been well studied for its benefits in promoting the health of energy-intensive muscular tissue, including skeletal muscle and the heart. Propionyl L-carnitine has been shown to increase cellular L-carnitine production. The amino acid L-carnitine facilitates the process of energy production in muscle cells.* Propionyl L-carnitine is also known to exhibit significant free radical scavenging activity in the circulatory and cardiovascular systems. Studies have also shown that propionyl L-carnitine may increase exercise capacity and overall energy in athletes and supports the overall metabolism of fat.
