This is not necessarily new – Framingham study found that low vitamin D was associated with with “an increased risk for progression of osteoarthritis of the knee” back in 1996. This seems to have been forgotten. Now a new study found “Participants with adequate 25(OH)D levels reported significantly less knee osteoarthritis pain compared to participants with deficient or insufficient levels, regardless of obesity status”.

A Cross-Sectional Examination of Vitamin D, Obesity, and Measures of Pain and
Function in Middle-Aged and Older Adults with Knee Osteoarthritis.
- Obese subjects were found to have lower Vitamin D
- However, when obesity was adjusted for, low vitamin D patients had more OA knee pains
For those interested, the framingham study is here:

In study in Calgary, Alberta, Canada found that virtually all subjects were low some part of the year if they were not on supplements. I check blood levels and they are always low. I think it as sleeping giant leading eventually to pain, weakness, osteoporosis, and falls in our elderly population.
