D-glucosamine and chondroitin
D-glucosamine is an important natural component of the articular cartilage. The substance supports the formation of synovial fluid, which ensures the joints working "like clockwork" in the true sense of the word. The more D-glucosamine is available in the body, the better the synovial fluid will be formed.
Chondroitin ensures for sufficient water and nutrients getting into the articular cartilage and being absorbed there. It keeps the articular cartilage moist and elastic, protecting it from damage caused by small cracks and brittleness. If there is too little chondroitin in the articular cartilage, then the cartilage "dries" out and degenerates. If, on the other hand, the cartilage is kept elastic, it can optimally fulfil its shock absorbing function in the joints.
That is why it is so important that, in addition to glucosamine, the joint is supplied with enough chondroitin. Active people in particular, who expose their joints to heavy strain during sports or work, should protect the joints from wear and arthrosis by taking the important nutrients in sufficient quantity.
