Bests & Worsts Reviews from Amazon

I used to buy this for my mother from Sam's Club or Walmart because she has joint problems, and she said it worked better than any other similar products. This one time I bought this bottle from Amazon, and after a few days, my mother said that her joints started to hurt again. Keep in mind that I did not tell my mom where I got these from, so she wouldn't know that the source has changed. I went back to Sam's Club and purchased another one for her, and she said she felt better with the new bottle. See comparison photo for the difference between the Osteo Bi-Flex from Sam's Club and this bottle I purchased from Amazon. The one on top was purchased from Amazon, the one at the bottom was purchased from Sam's Club.
