The New Zealand green-lipped mussel has a high density of beneficial bioactive substances such as glycosaminoglycans. This makes it a valuable raw material with many positive properties. Glycosaminoglycans belong to the group of amino sugars (simple sugars), are also referred to as food for the joints, and are a natural component of synovia (joint fluid) and cartilage. ArthroGreen Classic provides an important component for joint function thanks to its high content of New Zealand green-lipped mussel (unrefined mussel meat) and the glycosaminoglycans it contains, thereby promoting joint development.
