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.
Available in two sizes. 32 oz and 1 gallon.
