Collagen Revive+ features ch-OSA® — choline-stabilized orthosilicic acid, the only clinically tested bioavailable form of silicon — combined with biotin. Rather than supplementing collagen directly, this formula works upstream by activating fibroblasts — the body’s own collagen-producing cells — through silicon nutrition. Clinical trials have demonstrated meaningful improvements in skin elasticity, hair tensile strength, and nail quality with consistent ch-OSA® supplementation.* Supports skin firmness, hair resilience, nail integrity, bone mineral density, and healthy joints.* Non-GMO. Free of gluten, soy, dairy, and artificial additives.
