Unlock your potential for a lean, muscular body with Swanson L-Carnitine! A favorite among dieters and bodybuilders, this amazing amino acid helps the body metabolize fat to energize muscles for effective, productive workouts. L-carnitine is a cofactor—a type of molecule or compound needed by the body to complete enzymatic reactions—in the energy production process. It also helps to transport waste out of your cells, another factor in post-exercise muscle recovery. Emerging research also suggests that L-carnitine may offer unique benefits for mature adults, easing fatigue and supporting cognitive function.¹ Swanson L-Carnitine delivers 500 mg per serving to promote energy, a healthy body composition and more.
