What it is

Orthosilicic acid is a highly bioavailable form of silicon, an essential trace mineral. It is utilized to support the structural integrity and health of skin, hair, and connective tissues by providing the building blocks for collagen and keratin.

How it works

Orthosilicic acid directly participates in the synthesis of collagen and glycosaminoglycans in dermal fibroblasts. It also influences keratinocyte differentiation, contributing to stronger hair shafts and nails. Visible effects on skin and hair are typically observed after 8-12 weeks of consistent daily intake.

Who should take it

Adults looking to address dull skin, hair thinning, premature ageing. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.

Avoid / careful

Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.
