Many Australian equine oral joint supplements contain glucosamine and chondroitin sulfate, however Joint Guard Plus is unique in its combination of high levels of glucosamine with sodium hyaluronate in an oral powder form.
Glucosamine is utilised in the production of glycosaminoglycans (GAGs) which then combine with hyaluronic acid (HA) to form large proteoglycans in the matrix of cartilage. As such, glucosamine is a fundamental building block of the cartilage structure, and a growing body of evidence supports the pain-relieving and potentially chondroprotective properties of glucosamine.
Joint Guard Plus contains high levels of glucosamine (500 mg/g) to counteract the limited oral bioavailability of glucosamine in
horses.¹, ² The current recommended dose of oral glucosamine for horses is 10,000 mg per day.³
Chondroitin Sulfate (CS) is another fundamental building block of joint cartilage and oral administration in combination with glucosamine has demonstrated positive effects on equine
osteoarthritis.¹, ² Molecular weight markedly affects CS absorption in horses¹ and Joint Guard Plus contains a low molecular weight CS with proven, rapid oral bioavailability.
Sodium Hyaluronate, the sodium salt of hyaluronic acid (HA), is present in many body tissues including connective tissue and skin and in synovial (joint) fluid in very high concentrations. HA provides visco-elastic properties to joint fluid and functions as a lubricant.
In joint disease, inflammation breaks down HA which results in lowered viscosity of the joint fluid and further influx of inflammatory cells, exacerbating cartilage damage and joint disease.
Supplementation with Sodium Hyaluronate helps to replace HA lost as a result of joint disease and thereby restores lubrication of the joint, reduces inflammatory infiltrates and minimises ongoing damage.
Oral Administration – Trials (including several at Rood and Riddle Equine Hospital, Kentucky, USA) have shown benefits in the use of oral HA in horses which include positive effects on lameness incidence and severity, synovial effusion and inflammation, joint pain and improvement in pre-existing joint conditions.5,6,7
Circulating HA has a half-life of 2 days or less, necessitating daily supplementation to maintain long-term elevation of serum HA.6
Methyl Sulfonyl Methane (MSM), a metabolite of dimethyl sulfoxide (DMSO), has been shown to help relieve joint pain associated with osteoarthritis in humans8 and is recommended for managing horses with osteoarthritis.9
Long term treatment with Joint Guard Plus may help improve joint function.
