L Carnosine vs. L Carnitine: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 4, 2024
L-Carnosine is a dipeptide molecule with antioxidant properties, found in muscle and brain tissues, while L-Carnitine is an amino acid derivative vital for energy production and fat metabolism.

Key Differences

L-Carnosine, composed of beta-alanine and histidine, is known for its antioxidant and anti-glycation properties. L-Carnitine, derived from lysine and methionine, plays a crucial role in transporting fatty acids for energy production in mitochondria.
L-Carnosine is predominantly found in skeletal muscles and the brain, where it helps protect and stabilize cell membranes. L-Carnitine is essential for heart and muscle function, aiding in the conversion of fat into usable energy.
L-Carnosine has potential benefits in delaying the aging process and improving skin health. L-Carnitine is often used to enhance athletic performance and may aid in weight loss by improving fat metabolism.
Supplementation with L-Carnosine is suggested for neuroprotection and may benefit cognitive function. L-Carnitine supplementation is popular among athletes for its role in improving endurance and recovery.
L-Carnosine has been studied for its role in buffering lactic acid in muscles, potentially reducing fatigue. L-Carnitine, on the other hand, may improve blood flow and reduce markers of metabolic stress.
