L-Carnitine is a naturally occurring amino acid, which is concentrated in our bodies in tissues with high energy usages, such as the heart and the brain. However, factors such as aging, chronic illness, and intense exercise can deplete our reserves, increasing the demand for this amino acid. L-Carnitine is one of the safest and well-researched beneficial amino acids. Its function is to transport long chains of fatty acids into the heart of the cells, so that they can produce energy. L-Carnitine can also be used to promote muscular recovery for people who are highly active, as it may increase stamina, reduce muscle soreness and might provide a fat-burn effect.*
