TUESDAY, Sept. 24 (HealthDay News) -- Calcium supplements improve bone health in postmenopausal women, but vitamin D supplements provide no benefit in women with normal vitamin D levels, a new study finds.
"These findings suggest that vitamin D supplements over the recommended dietary allowance do not protect bone health, whereas calcium supplements do have an effect," study lead author Dr. John Aloia, of Winthrop University Hospital in Mineola, N.Y., said in a news release from the Endocrine Society.
