More than just vitamin C, our formulation contains vitamin C along with a number of synergistic plant compounds, such as citrus bioflavonoids, hesperidin, rutin, and quercetin. These plant compounds, known as bioflavonoids, help support the immune system. Vitamin C is a water-soluble vitamin also vital for immune function and for producing collagen, a structural protein connective tissue. The body requires vitamin C to form and maintain blood vessels, bone, and skin, metabolize amino acids, and synthesize hormones.
