LubriSynHA Hyaluronic Acid Pet & Equine Joint Formula 128oz - All-Natural High-Molecular Weight Liquid Hyaluronan - Joint Support for Horses Dogs Cats - Promotes Healthy Joint Function Made in USA

The only active ingredient in LubriSyn is hyaluronan. Hyaluronan (HA) is naturally found in bodies as part of synovial fluid the viscous substance that cushions and lubricates joints. Synovial fluid allows two adjacent cartilage caps to glide upon one another with minimal friction. LubriSyn is a liquid oral form of HA designed to help restore joint fluid as it degrades through aging and exercise. Does not include a pump.
