The Active Ingredient Is: Glucosamine (Hydrochloride Potassium Sulfate Form)

Glucosamine is a naturally occurring amino sugar used as a nutrient in joint health formulations. This form is derived from shellfish sources and used to support cartilage tissue integrity as part of a comprehensive joint support blend.

This formula also has included Chondroitin Sulfate and MSM, which help to support the overall joint-support matrix and tissue function.

What Does Glucosamine Do?

Glucosamine plays a role in the production of proteoglycans, which are components of joint cartilage. It is involved in maintaining cartilage structure and lubricating joints, in line with EFSA and NHS context for normal joint function.

Dr. Sawitzke of University College London found that combination nutrients may have a modest effect on joint comfort and function in certain populations.
