Pantothenic Acid and Vitamin C are potent nutrients that work synergistically to support healthy immune system response. Pantothenic Acid, also known as Vitamin B5, is a member of the B-complex family. Essential for many bodily functions, it is necessary for the metabolism of fats, proteins and carbohydrates. Additionally, Vitamin C functions as a powerful antioxidant, immune booster and improves iron absorption. It is also needed to make collagen, the “glue” that strengthens the muscles and blood vessels.
