Following the publication of the study, mainstream media posted headlines such as "Study Finds Another Condition That Vitamin D Pills Do Not Help" in theNew York Timesand "Are Vitamin D Supplements Useless" from Verywell Health.
Industry Responds to Vitamin D StudyThe Council for Responsible Nutrition (CRN) issued a response to the findings and an editorial on the study. “Vitamin D and calcium work in tandem to support bone health—calcium helps build and maintain bones, while vitamin D helps your body effectively absorb calcium," said Andrea Wong, Ph.D., CRN Senior VP Scientific and Regulatory Affairs. "So, these secondary study results are not surprising since VITAL was designed to assess vitamin D supplementation alone and did not include or control for calcium supplementation and intake. It seems obvious that investigating one without the other would produce disappointing results.
“Further, the study focused only on generally healthy midlife or older adults instead of individuals with vitamin D deficiency, low bone mass, or osteoporosis who may be more vulnerable to fractures and derive a benefit from vitamin D supplementation. The odds were stacked against this ancillary study before it even started.
“Despite the limitations of the ancillary study, the main VITAL findings and another ancillary study have added to the body of research on vitamin D’s impact on health, including promising results for reducing the risk of cancer-related death and autoimmune diseases. These and other important benefits have been completely ignored in the accompanying editorial, which outright dismisses vitamin D screening and supplementation."
