Which vitamin is necessary for metabolism and the health of the nervous system?

Vitamin B3, also known as niacin, plays a crucial role in metabolism as it is a component of coenzymes that are essential for converting carbohydrates, fats, and proteins into energy. Furthermore, niacin is important for the synthesis of neurotransmitters, which are vital for the proper functioning of the nervous system. By facilitating metabolic processes and supporting nerve health, Vitamin B3 ensures that the body can efficiently utilize nutrients while maintaining optimal brain function. This connection makes Vitamin B3 key in both energy production and nervous system health.
