Vitamin D Supplements of No Use in Improving Bone Health

It was previously believed that vitamin D can have wonderful benefits on one's bone health. To this end, many postmenopausal women are taking supplements to improve their chances at reducing their risk of bone deterioration and osteoporosis.

But according to a recent study, vitamin D supplements do not have a protective effect on women's bone health. This study was published in JAMA Internal Medicine.

Led by Karen Hansen, MD, researchers from the School of Medicine and Public Health of the University of Wisconsin took in 230 postmenopausal women who were deficient in vitamin D; all of them were under the age of 75 and most were white.

For the period 2010 to 2013, these participants were assigned to one of three groups. The first group received high doses of vitamin D, the second were given low doses, and the third was a placebo group. Those in the high-dose were given 50,000 IU twice each month while the low-dose women had 800 IU per day.

After gathering all the data per year, Dr. Hansen and her team discovered no substantial differences. While the placebo group saw a decrease in the calcium absorption rate by 1.3 percent, the women from the low-dose group had a 2-percent decline; the high-dose women, however, experienced a 1-percent improvement.

The minute advantage of the high-dose group did not amount to a considerable advantage over the other two groups in terms of spine health, muscle mass, physical mobility and overall bone mineral density.

The researchers, however, noted that these findings may not be applicable for women over the age of 75.
