Most people with arthritis have some nutritional deficiencies, including lowered levels of vitamins A, B6, B12, and C.
Glucosamine sulfate can help. The proper levels of minerals like magnesium and selenium is also important. Most arthritic patients need detoxification from heavy metals like mercury.
Eliminate refined foods. Eat a whole-food diet including unrefined sugar, salt, oil, and flour, and as much organic produce as possible.
Also, drink enough water.
