FitRenew features clinically tested ch-OSA® (choline-stabilized orthosilicic acid) complemented with biotin. ch-OSA naturally helps nourish your body’s beauty proteins by supporting and activating enzymes used by collagen-generating cells to make collagen. Regular orthosilicic acid (OSA) has to be stabilized to avoid polymerization, a process that decreases bioavailability. ch-OSA’s patented choline-stabilization technology prevents polymers from forming and ensures OSA’s optimal absorption. By combining ch-OSA with biotin, FitRenew offers an even greater level of beauty support.†
