What Is Pantothenic Acid?

Vitamin B5, also known as pantothenic acid, is a water-soluble member of the B-vitamin family. It serves as a precursor to coenzyme A (CoA), a molecule that plays a centre role in the metabolism of proteins, fats and carbohydrates. CoA is essential for the production of energy, the synthesis of red blood cells and the formation of acetylcholine, a key neurotransmitter. This makes pantothenic acid vital for overall cellular function and energy balance.
