What It Actually Is
L-Carnitine is an amino acid derivative that helps transport fatty acids into cells' mitochondria, where they're converted into energy — including in heart muscle tissue.
What Research Generally Shows
L-Carnitine has research support in cardiovascular contexts, including studies on heart muscle energy metabolism.
The Honest Gap
Research commonly uses doses around 500mg — nearly the entire 570mg blend on its own. We can't verify how much of the blend is actually L-Carnitine versus the other five ingredients.
