Reviews for Joint Support



The current formula uses sulfated forms of glucosamine and chondroitin. The glucosamine is described in the product formulation as a fully reacted glucosamine sulfate form.

Individual responses vary. Joint Support is designed for consistent use as part of a joint-support routine, but it is not presented with a guaranteed improvement or timeline.

OptiMSM® is the branded form of MSM used in the current Joint Support formula.

If you take prescription medications, use other supplements, have allergies or have questions about whether Joint Support fits your routine, consult your healthcare professional before use.
