The Active Ingredient Is: Silicon (as choline-stabilized orthosilicic acid)

Silicon, a trace mineral, is supplied in the choline-stabilised orthosilicic acid form, meant for enhanced bioavailability. This complex is vegan and non-GMO, and the product uses a plant-based capsule shell to deliver the ingredient in a bioavailable form.

This form is a patented ch-OSA complex created to optimise silicon delivery and support its role in connective tissue and hair, skin and nails health in vegan formulations.

What Does Silicon Do?

Silicon helps with normal functions linked to collagen and keratin synthesis, with evidence pointing to improvements in skin elasticity, nail strength and hair thickness in adults. Dr. Barel of University found that silicon-containing supplementation can positively influence skin properties when taken consistently.

EFSA-aligned research supports silicon’s involvement in maintaining normal connective tissue structure and function, contributing to daily vitality through its role in skin, hair and nails health.
