The Arthritis Foundation defines osteoarthritis as a chronic condition characterized by the breakdown of the joint's cartilage. There are numerous types of osteoarthritis and this disease can affect a variety of locations in the human body. Causes of osteoarthritis are both controlled and uncontrolled. Regardless of the category of osteoarthritis or the cause, the factor of vitamin D remains a debated one, particularly in relation to knee osteoarthritis. While this crucial vitamin plays an integral role in bone health and maintenance, it is possible it may do little in helping osteoarthritis.
What Is the Evidence?
Osteoarthritis produces pain due to loss of the cushion that cartilage provides joints. When this cushion is lost, the bones rub together and result in discomfort. Development of jagged bones can occur at the site, as well as inflammation. Typically, there is a positive correlation between the duration of the disorder with worsening symptoms. Some studies provide evidence that vitamin D can slow the progression of osteoarthritis, therefore, assist in relieving painful symptoms. Other findings suggest little or no benefit directly related to osteoarthritis.
Proponents for Vitamin D
In 1995, Dr. Timothy McAlindon and associates conducted a landmark study showing significant benefit of vitamin D in relation to slowing osteoarthritis progression. The study revealed that low levels of vitamin D were correlated with osteoarthritis development. The study actually showed a three-fold increase in risk of knee osteoarthritis, as well as an elevated risk of cartilage loss. There have also been studies over the past decade linking low vitamin D levels with bone spur formation, a painful condition usually associated with osteoarthritis.
Opponents Against Vitamin D
The majority of recent studies have failed to prove any direct positive result in slowing the progression of osteoarthritis with the help of vitamin D. A significant amount of pain is due to bone spur development which many researchers have shown cannot be diminished with the help of vitamin D. While opponents generally agree that vitamin D is essential to overall bone health, many do not agree with earlier studies that conclude that vitamin D may prevent progression of the disease.
To Take or Not to Take?
Most experts agree that vitamin D has a remarkably positive role in protecting bones, as well as other superb benefits. It has been proven countless times that vitamin D supplementation aids in the prevention of bone loss and other disorders. While it is undetermined how significant of a role vitamin D plays in regards to osteoarthritis, many agree that healthy bones are less likely to develop degenerative diseases such as osteoarthritis.
