BioSil, ch-OSA (Hair, Skin & Nails) by Natural Factors is a dietary supplement in capsule form. The product comes in a bottle containing 120 vegetarian capsules. The active ingredient in each capsule is choline-stabilized orthosilicic acid (ch-OSA).

Orthosilicic acid is a bioavailable form of silicon, which is known to support the health of hair, skin, and nails. It works by activating the body’s production of three essential beauty proteins: Collagen, which enhances skin elasticity; Keratin, which promotes strong and thicker hair, and Elastin, which gives skin its ability to bounce back.

BioSil is clinically tested, gluten-free, and does not contain any dairy, soy, peanut, GMO, or shellfish. The capsule shells are made from a hydroxypropyl methylcellulose, a vegan-friendly alternative to gelatin.

The recommended dosage is one to two capsules, taken one to two times daily. Each serving provides 5mg of Silicon (as Choline-Stabilized Orthosilicic Acid) and 100mg of choline.

BioSil is made by Natural Factors, a Canadian company known for its rigorous quality control and close ties with healthcare professionals.

With BioSil, users can aim to achieve improved hair, skin, and nail health through natural means. As with any dietary supplement, users are advised to consult with healthcare professionals before starting any new regimen. This product also should not be used if the safety seal is broken.
