A nutritional support system to promote the comfort zone in and around synovial joints TopSpec 10:10 Joint Support contains an excellent specification of nutrients to help the development and maintenance of healthy joints.

In ideal circumstances this enables joints to function smoothly and comfortably. TopSpec 10:10 Joint Support is designed to help support joints subject to excess trauma and/or repeated wear and tear. It is particularly suitable for horses working hard and elderly horses.
