Equine JointCharge Our exclusive user-mixed version of HA (Hyaluronic Acid) quickly improves joint mobility by recharging the lubricating fluid that's lost over time. Patent-pending formulation enables rapid uptake into the bloodstream for immediate distribution to joints, ligaments and other tissues. Each jug contains enough concentrate to accommodate 30-50 days depending on dosing schedule. Elderly horses or horses who are actively competing should follow a loading schedule (2x maintenance).
