1. Promotes Joint Health: Ultimate Glucosamine NAG contains glucosamine, a natural compound that helps to maintain healthy cartilage and cushion the joints, reducing joint pain and stiffness.

The Active Ingredient Is: N-Acetylglucosamine (NAG)

N-Acetylglucosamine, or NAG, is a compound that helps support normal joint structure and function. This product contains 100% N-Acetylglucosamine as a pure, single-ingredient powder, with no additives, and is described as gluten-free, soy-free and sugar-free.

This form is a standalone NAG powder supplied by Wellesley Therapeutics, designed for easy inclusion in drinks or meals as a simple, single-ingredient supplement.

What Does N-Acetylglucosamine Do?

N-Acetylglucosamine is involved in forming glycosaminoglycans, which help maintain cartilage structure and connective tissue integrity. Research suggests it may also support normal inflammatory processes in joint tissue.

Dr. Asimakopoulou of the University has reported that NAG contributes to joint repair and mobility by supporting cartilage and connective tissue health, aligning with EFSA-style functional descriptions.
