Osteoarthritis is one of the most common types of arthritis and is known as the "wear and tear" arthritis. This chronic condition causes your joint cartilage to break down, which causes stiffness and pain. Low levels of vitamin K contribute to abnormal bone and cartilage mineralization and are associated with osteoarthritis.
Supporting Research
A study published in the journal "Arthritis and Reumatism" in April 2006 found that low levels of vitamin K in blood plasma was associated with an increased risk of osteoarthritis in the hand and knee. A characteristic of osteoarthritis are osteophytes, or bony growths found near the end of your affected joints. Increases in vitamin K have been shown to reduce these osteophytes, which contribute to osteoarthritis pain.
Vitamin K Sources
While older adults tend to consume more vitamin K than younger adults, many older adults still do not consume enough vitamin K. Leafy green vegetables, including spinach, lettuce, kale and chicory, are rich in vitamin K. Other sources of vitamin K include broccoli, cauliflower, cabbage, milk and soybeans. Including enough vitamin K in your diet may also reduce your risk of bone fractures, bone loss and hardening of your arteries. The Linus Pauling Institute of Micronutrient Research recommends an intake of 120 micrograms of vitamin K each day for adult males and 90 micrograms for adult females.
Treatment
Lifestyle modifications may help you treat osteoarthritis. Eating a healthy diet that includes sources of vitamin K, vitamin D and calcium can promote healthy joint and bone health. Participating in low-impact exercises, including walking, swimming and cycling, may also relieve and improve some joint pain associated with osteoarthritis. If you are overweight, your doctor may recommend a weight loss program to relieve pressure on your weight-bearing joints. Physical therapy along with anti-inflammatory medications may also be part of your osteoarthritis treatment.
Considerations
While research has not proved that increased levels of vitamin K will prevent or repair damage caused by osteoarthritis, the Arthritis Foundation reports that adequate vitamin K intake may help slow its progression. Follow your doctor's instructions if you suffer from osteoarthritis. If you are concerned about your vitamin K intake, or intake of other essential vitamins and minerals, visit with a registered dietitian to develop an eating plan that meets your specific needs. Eating a well-balanced, healthy diet can help you get the essential nutrients your body requires for optimal health.
