According to an Australian study, Vitamin D cannot really treat osteoarthritis.

A new research shows that medication with Vitamin D for folks with knee osteoarthritis and low 25-hydroxyvitamin D does not actually reduce the pain in their knees and cartilages.

The study which was led by Australian experts was conducted by examining 413 individuals that were diagnosed with osteoarthritis. The patients were divided into two groups. The first group was prescribed to take vitamin D tablets as their medication while the other group were treated with a placebo.

After two years, the participants were then re-examined to find out if there are any improvements concerning their condition. Surprisingly, the study showed no difference between the group who took Vitamin D and the other who were prescribed with the placebo. Through the use of Magnetic Resonance Imaging, it was found out that the tibial cartilage volume which measures the knee pain is likely the same with each group.

In a statement, Dr. Changhai Ding explained the false belief concerning vitamin D as a medication for osteoarthritis.

"These data suggest a lack of evidence to support vitamin D supplementation for slowing disease progression or structural change in knee osteoarthritis," stated by the lead researcher which is also a professor at the University of Tasmania in Hobart.

In another account, Dr. Neil Roth, an orthopaedic surgeon at Lenox Hill Hospital in New York City explained that osteoarthritis can't be easily treated through oral medications.

"Osteoarthritis is a progressive disease and any medications patients take, orally or injected, won't alter the disease. The best we can do without a joint replacement is to modify some of the symptoms," said by the orthopaedic surgeon.

The said research is now published in the Journal of the American Medical Association (JAMA).
