So no, this has never been scientifically proven but one thing is sure on the other hand, it improves fat oxidation

The mechanism underlying carnitine's anti-aging effects involves multiple pathways: restoration of mitochondrial cardiolipin content and membrane integrity, enhancement of fatty acid oxidation to reduce lipotoxic stress, reduction of protein oxidation and carbonyl formation, improvement of calcium homeostasis and cellular signaling, and activation of stress resistance pathways that promote cellular resilience
