Research Summary
Clinical studies demonstrate that oral hyaluronic acid supplementation (typically 120–240 mg daily) improves skin hydration and elasticity over 4–12 weeks, with benefits most pronounced in low-molecular-weight formulations. Research on joint health shows modest benefits for osteoarthritis symptoms, though intra-articular injection remains the gold standard. Evidence for systemic absorption of oral hyaluronic acid is evolving, with some studies supporting improved tissue hydration and wound healing.
