Dr. Sundeep Khosla, president of the American Society for Bone and Mineral Research, said that the recommendations overall are very sound. Dr. Michael Holick, director of the General Clinical Research Center at Boston University Medical Center however was not wholly satisfied. He believes that most people should be taking vitamin D supplements. I think there is no downside to people increasing their vitamin D intake I personally get 3,000 IU of vitamin D a day. I have most of my patients on 3,000 IU a day and they are all in good shape, he said. Andrew Shao, senior vice president of scientific and regulatory affairs at the Washington, D.C.-based Council for Responsible Nutrition said, While an increase in the recommendations for vitamin D will benefit the public overall, such a conservative increase for the nutrient lags behind the mountain of research demonstrating a need for vitamin D intake at levels possibly as high as 2,000 IU/day for adults. Dr. Ishwarlal Jialal, a UC Davis endocrinologist whose research has linked low vitamin D levels to higher rates of pre-diabetes and diabetes, said the report was very fair in its assessment that the evidence showing the vitamin can help with conditions other than bone health is only preliminary.

Americans spent $1.2 billion last year on calcium supplements and $430 million on pills containing vitamin D, according to the Nutrition Business Journal.
