I am recommending this product along with Radiance Boron if you have sore joints. I have had one joint in my thumb removed because of arthritis and since returning to New Zealand found that my arthritis was terrible last winter. I did some research and decided to try these products. I got relief within three weeks, so I thought I would stop and see what happened - my pain came back with vengeance - so tried another brand but didn't work the combination of these two after another three week is amazing I can now move my fingers without pain and my lower back and neck do not have that burning pain anymore - i am not dreading the winter months this year. I am back in the garden and out on the farm walking up and down hills again YAH.
