What is it? / Overview
Hyaluronic acid is a major component of joint synovial fluid. Injectable hyaluronic acid (administered by a clinician) has meaningfully stronger evidence for joint pain than oral supplementation — oral hyaluronic acid's evidence base is much smaller and shouldn't be assumed to share the same effect.
How is it used? / Administration
Form: Oral hyaluronic acid (low-molecular-weight forms show better absorption)
Typical dose studied: 80–200 mg/day
Timing: With or without food
Do not confuse this with the stronger evidence base for injectable/intra-articular hyaluronic acid, which is a clinician-administered treatment, not a supplement.
How well does it work? / Evidence
? Emerging / limited evidence
Who should avoid it?
Already taking it? Evaluate benefit after 8–12 weeks; effects are gradual, not immediate.
