Research released by the Women’s Health Initiative ( WHI ) that showed that 1,000 mg calcium and 400 IU vitamin D in healthy postmenopausal women (between the ages of 50 to 79 years) did not reduce the risk of bone fractures. The study did show that the supplementation of calcium and vitamin D, combined with the recommended amount of calcium from the diet, significantly improved hipbone density. This study was a bit discouraging for many women who bank their bone health on just a daily calcium supplement product. There is so much more to do for bone health, including eating a wholesome diet, exercise and a healthy lifestyle. In addition, there is a branded ingredient compound called Ostivone®, known in the research as ipriflavone, which when combined with calcium has been shown to significantly increase bone density.
