The Active Ingredient Is: N-Acetyl-D-Glucosamine

N-Acetyl-D-Glucosamine is an aminosaccharide derived from shellfish and acts as a precursor to hyaluronic acid, supporting natural biochemical processes involved in tissue lubrication and moisturisation.

This form is provided as a shellfish-derived nutrient and the capsule comes in a cellulose-based, vegetable shell, suitable for non-GMO and gluten-free formulations.

What Does N-Acetyl-D-Glucosamine Do?

Scientific research suggests it participates in hyaluronic acid production, which is involved in joint lubrication and tissue resilience. It may also support mucosal protection by interacting with mucin in the digestive tract.

These roles contribute to normal joint function and digestive tract lining maintenance, aligning with established quality standards and general understanding of the nutrient's mechanisms.
