A compound in which one hydroxyl group of glucose is substituted by an amino group. The molecular formula is C6H 13O5N, commonly known as amino sugar, or amino sugar for short. 2- amino -2- deoxy -D- glucose, also known as glucosamine, exists widely in nature. 2- amino -2- deoxy -D- glucose usually exists in the form of N- acetyl derivatives (such as chitin) or N- sulfate and N- acetyl -3-O- lactate (cell wall acid) in microorganisms and animals. Relieve the pain, stiffness and swelling caused by arthritis.

Osteoporosis makes cartilage wear and tear, which eventually leads to fragmentation and spalling. Without the buffer of cartilage, joints are prone to stiffness and inflammation. Glucosamine helps to repair damaged cartilage, stimulate the formation of new cartilage, improve inflammatory symptoms, and relieve joint pain, stiffness and swelling.

● Strengthen cartilage structure to prevent joint failure.

With the aging of the body, joint tissue will be seriously worn. Glucosamine can protect and strengthen cartilage structure and prevent joint failure caused by joint aging.

● Lubricate joints and keep joint function.

Glucosamine can make proteoglycan lubricate joints, prevent friction pain between bones and joints, and make joints move freely.

The effect of glucosamine on lactation and children is not clear, so it is not suitable for lactating women.
