carnitine
Mitochondrial shuttle compound
Carnitine is a compound that transports fatty acids into cells' mitochondria, where they're burned for energy.
The body produces it naturally, but it's also sold as a dietary supplement marketed for weight loss, athletic performance, and heart health.
The trainer recommended L-carnitine before workouts.
