Glucosamine: Glucosamine is the major active ingredient in any supplement. It is a natural component of joint cartilage, and it can help heal, and even regenerate your horse’s joint cartilages. It also protects the joints and provides the building blocks for new tissue.

Chondroitin sulphate:  This also forms the building blocks for cartilage, synovial fluid, and even the connective tissues.
