L-Carnitine is like an amino acid and an energy-metabolizing B-vitamin had a baby, so it plays a crucial role in energy metabolism. It shuttles fatty acids into the mitochondria of the cell, where it can get burned and used as fuel, promoting increased ATP energy and release fatty acids. Our form of l-carnitine has also shown to reduce soreness, and reduce metabolic stress. All together, l-carnitine is a proven pre-workout ingredient tohelp burn fat and enhance recovery.
