Some people obviously experience different levels of pain as they age and unfortunately those who have done a lot of high impact sports tend to suffer more. The actual cause of most joint pain is inflammation, which occurs when the synovial fluid that cushions the joint, decreases and makes the cartilage vulnerable to breakage and friction.
An efficient joint pain medication needs to address the existing pain, which involves lubricating the joint to reduce inflammation, and build up the cartilage and connective tissues in the joint, making them stronger and less prone to damage. The two most beneficial substances for this job are Chondroitin and Glucosamine, which are often paired for optimal results. Cosamin DS uses both these ingredients but adds ASU to the formula. ASU is an avocado, soybean unsaponifiable which actually works synergistically with Glucosamine and Chondroitin. Also added to the mix is green tea, a powerful anti-oxidant that further helps reduce inflammation by fighting infection.
There are numerous choices in the joint support category containing vastly different formulations. You should do your research on the different formulas prior to making your choice. You will find not all products are created equal. You should find one that contains the quality and quantity of necessary ingredients to positively effect change and relief of pain.
