The Active Ingredient Is: Silicon (Choline-Stabilized Orthosilicic Acid)

Silicon is a trace mineral that’s involved in the normal formation of connective tissues and keratin-based structures. The active form in this product is choline-stabilised orthosilicic acid, a silicon complex that helps its biological activity.

This formula uses the ch-OSA complex as its main source, with vegan and GMO-free ingredients and without common allergens or artificial additives.

What Does Silicon Do?

Silicon helps support the production of collagen, elastin, and keratin, which are important for the integrity of hair, skin and nails as part of normal physiological function.

This supports daily wellness by contributing to the maintenance of healthy hair, skin and nails through the body’s natural structural proteins.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.

BioSil is the brand we chose as our partner for this ch-OSA based supplement because of its clear focus on supporting the body's natural production of collagen, elastin and keratin.
