Additional Information

How It Works: L-Carnitine is a non-essential amino acid that is abundant in heart, muscle and liver tissues. It helps to maintain metabolic health by facilitating the transfer of long-chain fatty acids across the mitochondrial membrane for cellular energy production.* In addition, it thereby assists the body in using fat for energy.* It naturally occurs in red meat and other animal source foods, but some people may have an increased need for dietary L-Carnitine due to high fat and vegetarian diets. Clinical studies indicate that L-Carnitine may promote exercise performance and recovery.*
