I did my homework specially. This glucosamine hydrochloride capsule has a good reputation and has been highly recognized by patients with osteoarthritis. Moreover, it is an OTC class A drug with the approval of Chinese medicine, and the quality is also guaranteed. Can be used for treating and preventing osteoarthritis in various parts of the body, including knee joint, shoulder joint, hip joint, wrist joint, cervical spine joint and ankle joint. If it is a knee problem, you will see the curative effect if you insist on taking it. Moreover, the nutritional chicken amino sugar has a great advantage, that is, it is pure natural amino sugar extracted without any auxiliary materials, so the amino sugar content is high (the effect is better) and the safety is high. Arthritis needs long-term treatment, but even taking it for a long time will not cause any burden to the elderly, so it is safe to buy it for the elderly. It is believed that the problem of knee pain in the elderly will be improved by timely, scientific and sufficient supplementation of ammonia sugar.
