D Pantethine is a more stable and active form of pantothenic acid (vitamin B5). It is also a precursor of coenzyme A (CoA) in the body.
It is known for its beneficial effects on metabolism, energy production, and lipid metabolism.
Pantethine is often used as a supplement ingredient to support heart health and metabolic function.
It is more effective than regular pantothenic acid because it has a higher bioavailability and is more easily absorbed.
