Bottom line. Ginkgo shows no meaningful benefit for joint health at studied doses (Grade D, very-low certainty), especially in adults with knee osteoarthritis. [1 RCT]

Direction
null
Magnitude
Narrative review: Ginkgo biloba extract (EGb 761) has demonstrated anti-inflammatory, antioxidant, and chondroprotective properties in experimental and preliminary clinical research for knee osteoarthritis, but this is a synthesis of mechanistic and early findings, not a meta-analysis of controlled trial outcomes. Too preliminary for a confident effect estimate.

What dose was used in studies of Ginkgo for joint health?

Studied doses for Ginkgo in joint health trials cluster around not standardized. See the dose block for the specific range and how it varies by form.

Does Ginkgo work for joint health if I'm not deficient?

The effect concentrates in adults with knee osteoarthritis. If your baseline is normal, expect a smaller effect than the trial averages.

Ginkgo or the next-best alternative for joint health?
