New study suggests low vitamin D status is a risk factor for knee osteoarthritis

A recent study conducted in part by USDA-funded researchers has found that insufficient vitamin D status is associated with an increased risk of developing knee osteoarthritis.

Osteoarthritis (OA) is the most common form of arthritis, affecting nearly 28 million Americans. It occurs when the natural cushioning between the joints wears down over time, allowing the bones to rub together. This condition most commonly affects the joints in the hands, knees, hips and spine.

OA worsens over time, and no cure exists. Therefore, there is a large interest in finding ways to prevent or treat the disorder.

Recently, researchers assessed the relationship between vitamin D status and the progression of knee osteoarthritis. The study included 418 volunteers who were between the ages of 45 and 79 years with evidence of knee osteoarthritis in at least one knee. The volunteers were followed for a total of four years, during which time the progression of the condition was tracked.

The researchers found that participants with low vitamin D levels (less than 15 ng/ml) had more than double the risk of their knee osteoarthritis worsening compared to the volunteers with healthy vitamin D levels. In addition, people who had both low vitamin D and high parathyroid hormone levels had more than three times the risk of their condition worsening than those with healthy levels of both.

    I’m astonished and embarrassed to realize, upon reading this, that I have not given a thought to the fact that I have not experienced progression of my osteoarthritis in my knees for 7 years. I’ve been aggressive about D for only about 8 or 9 years. From time to time, I’ve contributed the lack of pain in my left knee to the fact that I was no longer favoring my right knee (having gotten a partial replacement in 2008), that it let me put more balance on the replaced knee and cut the left one some slack. For a lot of reasons I know that is not the case now. Egad.

    Today’s Parade Magazine features “EXPERTS” on health and the only MD listed is JJ Levenstein. She says …”As a woman over the age of 50–and proud of it–I know that my bone health is a priority. So I have at least 600 IU vitamin D and 1200 calcium daily.”

    :She is on Hallmark’s Home and Family TV show and is a Fellow of the American Academy of Pediatrics. Wish she had enough time to get the full story on D3.

    Here’s what I am consistently hearing in the mainstream medicine world of which I am so painfully constrained: “Oh vitamin D is wonderful! Make sure you take your 800 iu D3 daily. Or perhaps 1,000–2,000 iu D3 daily if you’re a candidate for osteoporosis. But, please don’t take more. Wonderful vitamin D is potent, so we must be careful.” My reply: “Bull feathers.” I am beginning to think that main stream medicine has found a perfect way to down play the miraculous benefits of vitamin D. It agrees to its importance. It recommends a piddly amount that would not even improve the health of a fly, and then it cautions against doses that would many times cure disease. What a perfect way to stranglehold the progress of vitamin D.
