I have arthritis and was taking this product for a while. It took the redness out of my joints and the pain was pretty much gone. I go to the US every winter and didn't buy enough so I decided not to take them any longer. Big mistake. After just one month my joints were very sore and very red. I ordered a different brand but they were very large pills and I didn't really like them all that much. They worked but prefer this brand so will be sure to buy a 5 month supply before we go south this fall. It may not work for everyone but it works for me.
