AVELOR SUMMARY

Silicon dioxide in supplements is an anti-caking agent, not a therapeutic ingredient. Colloidal silica (Biosil® / ch-OSA) is the therapeutic form, choline-stabilized orthosilicic acid that provides bioavailable silicon for collagen synthesis. Regular silicon dioxide supplements do NOT provide bioavailable silicon. for the therapeutic form. --- *Reviewed by the Avelor Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
