What is the function and efficacy of glucosamine chondroitin?

If people often feel uncomfortable with articular cartilage, it is very helpful to eat glucosamine chondroitin every day. Aminoglycan has the reputation of joint protective agent, which is very helpful for the repair of damaged chondrocytes. Chondroitin sulfate can cooperate with glucosamine to protect the health of cartilage synovium. I chose Nutrilite Chondroitin Calcium Tablets for my parents, which can not only supplement enough amino sugar and chondroitin sulfate, but also efficiently absorb bone nutrients such as CPP and calcium carbonate, as well as China's classic prescription Rhizoma Drynariae. This product is not only nutritious, but also easy to absorb. When parents are old, their absorption ability is poor. This product just makes up for this deficiency. After eating for a while, their low back and leg pain improved a lot.
