The Active Ingredient Is: Glucosamine (HCl Potassium Sulfate GreenGrown)

Glucosamine is a natural building block used in keeping cartilage structure and joint integrity, sourced here as GreenGrown Glucosamine HCl Potassium Sulfate for a vegan-friendly option.

This form is made by plant-based fermentation and is suitable for anyone avoiding animal-derived ingredients.

What Does Glucosamine Do?

Glucosamine plays a role in the formation of glycosaminoglycans and proteoglycans, which contribute to cartilage composition and cushioning. This mechanism supports normal joint function in line with EFSA interpretations and NHS guidance on cartilage biology.

Dr. Wandel from a leading university stated that glucosamine is a well-tolerated supplement in adults for maintaining joint comfort and mobility as part of a balanced lifestyle.

This supplement isn't intended to diagnose, treat, cure, or prevent any disease.
