Glucosamine is a naturally occurring compound that is chemically classified as an amino sugar. It serves as a building block for a variety of functional molecules in your body but is primarily recognized for developing and maintaining cartilage within your joints. Glucosamine is frequently used to both treat and prevent joint disorders, such as osteoarthritis. It may be taken orally or applied topically in a cream or salve.

What are Glucosamine benefits?

Glucosamine is a compound produced naturally in the body and is chemically classified as an amino sugar. Glucosamine is found in high levels in shellfish and is generally used to care for joint health, primarily to relieve pain. Although this compound is used to treat symptoms of bone and joint disorders, studies indicate other benefits of glucosamine, such as in the treatment of various inflammatory diseases. It is worth remembering that glucosamine supplementation cannot cure osteoarthritis, but it can slow down the progression of the disease. So take our 3-step quiz and find out how to improve your body and other supplements that can help with bone health!

Bone and Joint Health Glucosamine and Bone and Joint Health

Bone and joint health are deeply affected by vitamins, hormones and minerals, such as calcium, vitamin D and thyroid hormones. Supplements that affect bone and joint health help their structure and strength, in addition to contributing to the healthy balance of involved nutraceuticals.

  • Joint Inflammatory and Stiffness

    Joint stiffness and inflammation is the feeling of limited joint movement. This sensation may or may not be caused by weakness and is associated with long periods of immobility. Stiffness is common with arthritis, and inflammation worsens the pain and limits certain movement. The timing and cause of the inflammation and stiffness can only be diagnosed by doctors, but preventive and palliative treatments are options for those who suffer from these complaints.
