Carnitine is a naturally occurring amino acid derivative involved in energy production. It plays a critical role in the transport of long-chain fatty acids into the mitochondria, where they are oxidized to produce energy. This function makes it especially relevant in the context of fat metabolism.
In the supplement world, L-carnitine is often marketed for its potential to support fat loss and enhance exercise recovery, particularly in endurance-based physical activity. While evidence on its fat-burning effects in humans is mixed, it has shown promise in reducing muscle damage and improving post-exercise recovery.
L-carnitine is also important for cardiovascular health and mitochondrial function, supporting energy metabolism in muscle cells.
Synonyms:
L-Carnitine, Acetyl-L-Carnitine (ALCAR)
Benefits:
- May support fat metabolism
- Aids in energy production
