Low Vitamin D May Harm Knees

More kudos for vitamin D! A new study in the journal Arthritis & Rheumatism claims insufficient vitamin D may cause cartilage loss in knee joints. For the study, involving 880 men and women, ages 51 to 79, scientists measured blood levels of vitamin D and knee cartilage volume. And 3 years later, retesting of 353 people revealed 58% had changes in knee cartilage and worsening osteoarthritis, both men and women with low vitamin D had less knee cartilage; Reuters reports.

Vitamin D is strong medicine and we get vitamin D from the sun’s ultraviolet rays. Vitamin D functions as a hormone, telling our intestines to absorb calcium and phosphorus, which builds strong bones and prevents things like rickets, depression and even difficulty thinking!

In his DVD Osteoporosis Protection for Life, Dr. Fuhrman explains why vitamin D is so critical, the importance of proper diet and he demonstrates a number of bone strengthening exercises.

This is fascinating. Alternatively, I wonder if restoring once-low vitamin D levels can re-build cartilage volume.

Hi Gerry
I recently rejoined a commercial gym, and I include a bit of treadmill running (1 mile, twice per week) among my exercises. I have been a bit sporadic in taking my D, but I will be more careful now.
Thanks, Steve
