Calcium tablets and aminoglycan chondroitin can be taken together because among many elderly people, there is not only joint degeneration and cartilage wear, but also osteoporosis. Aminoglycan chondroitin can mainly play a role in improving the metabolism of joint cartilage cells and alleviating joint degeneration, while calcium tablets can actively replenish the body’s basic calcium content and prevent further development of osteoporosis, so the combination of the two drugs can simultaneously treat and prevent osteoarthritis and osteoporosis. Of course, there are also drugs that can treat both diseases, such as chondroitin sulfate calcium tablets, which contain both the basic components of cartilage and calcium ions, and can treat both degenerative diseases at the same time.
