It’s time to upgrade your vitamin C. We’ve elevated standard C by combining citrus bioflavonoids and rosehips – nature’s secret to enhanced absorption – and putting it all in a timed-release tablet, giving you the C of the future. Working in synergy, this powerful combo optimizes the body’s usage of vitamin C, provides antioxidant protection, keeps collagen healthy, and helps promote capillary strength.* Natural Factors’ timed-release technology allows for a gradual release of the nutrients over a six-hour period.
