I bought 4 bottles thinking I would save some money. Usually I get this from my Chiropractor. This is made right here in Cedar Rapids Iowa by a Chiropractor and is wonderful. But when I received these 4 bottles, all with the same lot number, I noticed the color was off. There's SUPPOSED to beGlucosamine, Chondroitin, MSM, Boswella, curcumin, Bromelian, Chinese Skull Cap, Acacia, Milk Thistle Extract, etc....and you can taste them.The ones from Amazon, looked and tasted like orange pop. I noticed the difference after a week. The correct Flex Easy really works. This stuff I ordered, definitely does not!.I'm stuck with 4 bottles of worthless orange juice.Dont buy from this vendor, buy from your Chiropractor. I know I will from here on out.
