Complete joint support formula.

Joint Armor is scientifically formulated to provide the four most essential elements for joint health: glucosamine, chondroitin sulfate, hyaluronic acid, and manganese sulfate. While other products include one or two of these ingredients, Joint Armor provides all four elements at therapeutic levels, all for the price of one supplement.

Joint Armor includes:

Per  7 g scoop

Glucosamine HCl …………………2,500 mg

Glucosamine sulfate ……………2,500 mg

Chondroitin sulfate ……………..1,200 mg

Hyaluronic acid ……………………..100 mg

Manganese sulfate ………………..100 mg

Glucosamine and Chondroitin Sulfate

Glucosamine and chondroitin sulfate are key nutrients necessary for maintenance of normal joint function. Glucosamine is used as a substrate for certain components of the cartilage matrix, while chondroitin sulfate plays an important role in controlling the enzymes associated with inflammation and tissue destruction. Numerous studies have documented the benefits of combining these two ingredients to joint health.

Studies using equine cartilage explants (small pieces of actual living tissue) have shown these ingredients complement each other in inhibiting the production of inflammatory cells. Interestingly, when these ingredients were used independently of each other, they did not show similar benefits (Orth et al., 2002; Schlueter and Orth, 2004; DeChant et al., 2005).

Glucosamine and chondroitin sulfate have been evaluated in several field studies. In a double-blind placebo-controlled study (Hanson et al., 2001), 14 horses with progressive forelimb lameness showed significant improvement (evaluated by lameness specialists using standardized lameness scores) when administered a treatment of glucosamine and chondroitin for a 28-day treatment period when compared with the control group. In a more recent study (Rodgers, 2006), administration of glucosamine and chondroitin significantly decreased the necessity and frequency of intra-articular therapeutic injections of the hock joints in working show hunters and jumpers.

Hyaluronic Acid

Hyaluronic acid (HA) is an integral component of synovial fluid and articular cartilage, and is responsible for lubrication of the joint surfaces. While glucosamine and chondroitin sulfate work mainly on the cartilage, HA is more beneficial to the joint fluid. In a study conducted by Bergin and coworkers (2006), oral HA was effective in reducing synovial effusion (an abnormal collection of fluid) following arthroscopic surgery for removal of osteochondritis dissecans (OCD) lesions in joints.

Manganese Sulfate

Manganese is an important cofactor in the formation of the cartilage matrix and synthesis of connective tissue.
