L-carnitine is synthesized from the essential amino acids lysine and methionine. Because approximately 98% of the body's L-carnitine supply is found in muscle mass, and the nutrient needs of active adults outweigh those of inactive people, ON offers this L-carnitine supplement providing 500 mg of pure L-carnitine per 1-tablet serving.
As a dietary supplement, consume 1-2 tablets twice daily before meals.
