Related Reading: Glucosamine for Dogs

Glucosamine is an amino sugar produced by the body for use in tendons, ligaments, cartilage, and the fluid around the body's joints. Glucosamine can be helpful for joint health (e.g., as a supplement) to people, dogs, and horses to support healthy joints because it provides building blocks for synovial fluid, cartilage and connective tissues.

Glucosamine is one of the most commonly used dietary supplements in the United States. Commercial glucosamine is typically extracted from shellfish. Because it is taken from the shell rather than the flesh of shellfish, glucosamine supplements are generally safe for those with shellfish allergies; however, it is best to consult a doctor first if you have a shellfish allergy before consuming glucosamine.

The science behind the supplement

Glucosamine comes in three forms: glucosamine sulfate, glucosamine hydrochloride (used by Springtime), and N-acetyl glucosamine. Glucosamine is one of the essential components of cartilage and it is made by the combination of glucose and the amino acid glutamine by the enzyme glucosamine synthetase. Human and animal studies suggest that glucosamine supports healthy cartilage production and maintenance. Although it is a stand-alone supplement, glucosamine for joint health seems to be more effective when combined with chondroitin sulfate.

Proven effective in a major U.S. medical trial

The University of Utah School of Medicine coordinated a large-scale, multicenter clinical trial. The study found that glucosamine combined with chondroitin sulfate provided significant joint health benefits 79% of a study group. For more info on the study, click here.

Springtime uses the highest quality glucosamine -- third-party tested for potency, purity, and safety. Below you will find more information on Springtime products containing glucosamine:
