Q: I am a 59 years old man suffering from osteoarthritis and rheumatoid arthritis for the last 10 years. I had a knee replacement surgery on my left knee. Now I have considerable pain in my right knee too and will have to go for replacement of the right knee. Besides this, I have pain in all my small joints also. I came to know that Seatone is a good calcium provider. Please give me details about Seatone.

A:Seatone is not a medicine but so called "nutritional supplement." Such products do not undergo legally mandatory clinical trials acceptable to drug regulators. Their efficacy and safety is not independently assessed. It would not be wise to spend money on such products advertised on the internet. Instead you should seek expert orthopaedic surgeon's advice.
