Natural Collagen Production with ch-OSA® and Biotin

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.

Noticeable improvement in hair, skin and nails

FitRenew has worked well for improving my hair, skin and nails so far. I’ve noticed some improvements and plan to keep taking it. Easier that mixing collagen powders.
