Vitamin C is important for immune function and antioxidant protection, as well as collagen and connective tissue production. Multi-Element Buffered C adds calcium, magnesium and potassium to ascorbic acid to create a buffered product that is gentle on the stomach. Because doses of vitamin C in excess of 1 gram per day can deplete some essential minerals and disrupt the body’s pH balance, this formulation includes minerals and trace elements to help maintain a proper acid/base balance. Quercetin, a potent bioflavonoid, and reduced L-glutathione, an antioxidant, are included to potentiate the function of vitamin C.
