It would be beneficial to boost your intake of Vitamin C and Vitamin D because doctors believe that being deficient in these minerals can lead to loss of cartilage and arthritis pain.  A study recently unveiled that people who have a diet rich in Vitamin D or took a Vitamin D supplement reduced their risk of worsened arthritis symptoms by 75%.  Doctors from this study recommend consuming 400 IU to achieve optimum results.  This mineral is also plentiful in oily fish, Vitamin D fortified bread, and dairy products.  Sunshine is also a great way to soak in some Vitamin D.  A different study of 25,000 people revealed that consuming 500-1000 mg of Vitamin C reduces a person’s risk of developing arthritis by 30%.  They recommend consuming anywhere from 500-1000 mg of Vitamin C supplement daily.   Foods that contain Vitamin C include kidney beans, oranges, strawberries, mangos, pineapple, and bell peppers.
