can you take l carnitine while bulking L-carnitine benefits, uses & dosage: A complete guide Why You Might Take L-Carnitine

It seems that the reason carnitine was unable to increase muscle carnitine concentration in these studies for 2 reasons: Poor bioavailability (only 20% for of a 2-6 g dose is absorbed) and Because the transport of carnitine into the muscle was limited

For this reason, supplementing with this amino acid may especially benefit endurance athletes, such as long-distance runners, swimmers or cyclists

Notably, carnitine monooxygenase (CntA) catalyzes the conversion of carnitine into TMA and malic semialdehyde [31], while carnitine dehydratase (CD) facilitates the dehydration of carnitine to produce crotonobetaine [32]
