SISU Ester-C Duo Pack
THE BETTER VITAMIN C
What makes Ester-C better? In the vast world of vitamin C’s, only one provides 24-hour immune support and potent antioxidant protection. Ester-C is a unique, patented, non-acidic form of vitamin C that is pH neutral so it’s gentle on the stomach and tooth enamel.
It is clinically proven to be absorbed faster and remain in the white blood cells of the immune system longer, and is the only form that contains active vitamin C metabolites threonate and furanone for enhanced cellular absorption and retention. Don’t settle for anything less than Ester-C®. Nothing Else Works Like It.
