Boston University rheumatologist, Tuhina Neogi, reported at the World Congress on Osteoarthritis in Brussels that people who are deficient in vitamin K has twice the incidence of developing osteoarthritis of the knee. Those who eventually developed arthritis in both knees over a 30 month period were 3 times more likely to be vitamin K deficient. Vitamin K is also a factor in Rheumatoid arthritis and in Osteoporosis. Supplements containing both Vitamin D and Vitamin K are now available, and should be considered for a comprehensive preventive program.
