Glucosamine in horses

In horses with (presumed) osteoarthritis, glucosamine is almost always added to the diet. Glucosamine reduces the wear and tear of joint cartilage. Glucosamine is a simple amino sugar consisting of a glucose molecule in which the hydroxyl group is replaced by an amino group.

Scientific name:

C6H13NO5

Type:

Amino sugar

Effects of glucosamine in horses:

• Supports cartilage
• Lubricates joints

Function of glucosamine

Glucosamine is a natural substance found in almost all tissues, but especially in cartilage. Glucosamine helps to keep cartilage moist so it can absorb shocks and keep joints flexible. Glucosamine is also a component of hyaluronic acid, which is responsible for lubricating the joints.

Glucosamine also acts as an amino acid in the body and helps in the production of proteins.

Absorbability of glucosamine

The addition of glucosamine to a horse's diet is increasingly raising questions. Various studies have indicated that it is questionable whether glucosamine can even be absorbed. It is clear that only plant-based or glucosamine from shellfish is absorbable, synthetic glucosamine cannot be utilized by the horse. When purchasing a glucosamine supplement, pay very close attention to the origin.

As glucosamine travels a long way through feed, researchers estimate that only 8% is absorbed. It is therefore a very ineffective supplement. For joint support, it is better to choose the hydrolyzed form of silicon. This is highly absorbable for the horse and stimulates the production of natural glucosamine.
