I absolutly love this product and would highly recommend to anyone with joint problems. After doing some research online I found this product and read rave reviews about, I knew I had to try this product. After three days of being on Major Glucosamine and Chondroitin double strength caplets I started noticing a difference. My aching joints weren't aching anymore and my knees that would always pop and crack when workoing out weren't doing that anymore. As I continued to take this product I noticed all symtoms were gone, this product is amazing! If you are having any kind of joint pain, stiffness, popping or cracking joints I highly recommend this product it works wonders! Do not be fooled by other brands, I bought a big name brand when I couldn't find this and I will tell you now it was a waste of money, there is absolutely no comparision in product, I promise you.
