99.0% pure glucosamine hydrochloride (derived from shellfish). No added bulkers or fillers.

Glucosamine is a proven supplement for joint health. Research in humans with osteoarthritis showed improvements in pain score and function score after taking glucosamine daily on a long-term basis. The compound has been shown to promote cartilage metabolism, therefore supporting joint structure and maintaining mobility.

Research in humans has shown that 1500 mg (1.5 g) daily is needed for effectiveness, so there is no point in feeding this, or even double this amount to a horse.

**Vets and nutritionists recommend 10 g of actual glucosamine daily, which equates to 12.5 g of glucosamine hydrochloride**


Glucosamine is one of the most popular and useful equine joint supplements. Glucosamine is a sugar-containing compound produced in the bodies of animals, and humans, from glucose. It is suitable for long-term use because glucosamine is a natural substance found in the body and has no known side-effects. It can safely be taken alongside other supplements and herbs. Glucosamine also has the advantage of being readily bioavailable and easy to administer.

Glucosamine hydrochloride is a vital building block in the body essential for the healthy and effective production of collagen and other key joint tissue components.

A horse's joints are designed to efficiently absorb shock, allow smooth, comfortable movement, and bear the weight of the horse’s body. There are three different types of equine joints: fibrous, cartilaginous, and synovial.

  • Fibrous joints are more or less immobile. They include joints in the skull and those between the shafts of some long bones
  • Cartilaginous joints have limited movement. These are the joints of the pelvis and vertebrae as well as growth plates, which extend a bone's length during the horse's growing years
  • Synovial joints are the most active joints in the horse's body. They consist of two bone ends covered by a smooth, thin layer of resilient articular cartilage. You will find them in the fetlock, knee, elbow, hock, and stifle joints. These are joints which do a lot of work and suffer the most wear and tear
Synovial fluid is important to keep the joint nourished, well-lubricated, moving comfortably. Glucosamine is essential so that the body can produce enough of this fluid in high quality. A key ingredient in synovial fluid is hyaluronic acid, also known as sodium hyaluronate or hyaluronan, which lubricates the synovial membrane. Glucosamine for horses is a precursor, or building block, for hyaluronan.

Old age, injuries or a stressful, busy workload and lifestyle can all result in your horse’s natural supplies of glucosamine running down. The articular cartilage, which surrounds the joint, can then be affected and become damaged and roughened, losing its smooth surface.

Normal articular cartilage is made up of cells called chondrocytes which produce and regulate the much more abundant matrix. The matrix is composed of a tough protein called collagen surrounded by proteoglycan. Proteoglycan allows articular cartilage to hold a lot of water which it needs in order to allow virtually frictionless movement between the bones. Proteoglycan is made up of protein and glycosaminoglycans (GAGs). These GAGs are produced by the chondrocytes - and glucosamine hydrochloride is the building block of articular cartilage GAG.

Taking a glucosamine supplement has been found to support the performance of joints and also to aid the body's natural responses to pain or discomfort.

Young, as well as old horses can have issues with joint health, and therefore benefit from the supportive effects of glucosamine. Both developmental disorders and injuries can affect younger horses, and glucosamine helps support the re-building of collagen within the joint cartilage.

Are you feeding the best joint supplement for your horse?
There are a huge number of horse joint supplements out there - but check the ingredients to make sure they can be effective. Just as important, check the amount of each ingredient per daily serving.

Daily servings of a few hundred milligrams of vitamin C or tens of milligrams of manganese will not make any difference to a balanced diet in a healthy horse - who should already be ingesting at least 400 mg of manganese daily and should be producing his own supply of vitamin C.

Extra vitamin C may be necessary for a sick, old or stressed horse, but to be effective it needs to be fed at a rate of 5-15 g daily.

Look at the product label to make sure each daily serving supplies enough active ingredients. The table above lists the amounts of active ingredients needed. To calculate amounts per daily serving where they are given per kilogram, divide the daily serving by 1000 and then multiply this by the amount of active ingredient in 1 kg.

Pegasus joint supplements include the most appropriate ingredients, provided at effective levels in each recommended serving. With Pegasus joint supplements, you know that the numbers add up for you and your horse.
