What It Actually Is
L-Carnitine is an amino acid derivative the body produces naturally and also gets from foods like red meat. Supplemental forms are commonly used in sports and weight-management products.
What Research Generally Shows
Carnitine's primary role is shuttling fatty acids into mitochondria, the cell's energy-producing structures — the reasoning behind pairing it with thermogenic ingredients like EGCG and cayenne that mobilize fat in the first place.
Why It's Dosed At 500mg
500mg is a commonly used capsule dose, though some studies use higher amounts — worth keeping in mind if you're comparing against specific research.
