The Active Ingredient Is: Glucosamine Sulphate

Glucosamine sulphate is a naturally occurring aminosaccharide and a basic building block used in the synthesis of glycosaminoglycans and proteoglycans that form cartilage. This form is derived from shellfish sources and is commonly used to support joint structure and function.

This formula uses glucosamine sulphate as the active ingredient and is produced in a GMP-certified facility to support material quality and supply chain transparency.

What Does Glucosamine Sulphate Do?

Glucosamine sulphate contributes to the formation of cartilage components and supports joint integrity as part of normal cartilage maintenance. Scientific research suggests this form may be associated with improved joint function in osteoarthritis settings, and EFSA-consistent wording supports its role in normal joint health.

Dr. Wandel from University College London found that glucosamine sulphate might provide some pain relief for people with knee osteoarthritis, aligning with robust clinical evidence in this area.

This combination also includes quality control measures so the ingredient maintains its structural role in cartilage and contributes to normal lubrication and cushioning within joints.
