C-Fence® by Nutriventia is a direct compressible granular system of Vitamin C, designed with patented modified release technology. It delivers periodic bursts of Vitamin C for sustained 24-hour antioxidant coverage. Manufactured with nature-derived excipients, C-Fence® provides enhanced flow properties, overcoming Vitamin C’s hygroscopic nature and poor compressibility. Clinically validated pharmacokinetics confirm extended plasma presence. This ingredient supports immune, cardiovascular, brain, and skin health while offering consistent performance for once-daily supplement formulations.
