What is in L-carnitine supplements?
L-carnitine supplements typically contain synthetic L-carnitine, often in capsule or powder form. They're marketed to boost energy and aid fat burning, especially for exercise. The Yale study used L-carnitine itself, not specific supplements, so it didn't test if these products cause inflammation.
