WASHINGTON (WUSA9)- A new study has found that vitamin D supplements may not be so valuablein preventing ourbodies from disease.
The study of randomized trials, published in The Lancet Diabetes & Endocrinology, calls into question whether or not we should rely on taking supplements of the "sunshine vitamin" to help our bodies fight off acute and chronic disorders like cancer, heart disease, Parkinson's disease, diabetes and death.And scientists havefoundthat low levels of the vitamin in the body are "not a cause but a consequence of ill health," according to The Lancet.
According to lead author Professor Philippe Autier from theInternational Prevention Research Institute in Lyon, France, "What this discrepancy suggests is that decreases in vitamin D levels are a marker of deteriorating health. Ageing and inflammatory processes involved in disease occurrence and clinical course reduce vitamin D concentrations, which would explain why vitamin D deficiency is reported in a wide range of disorders."
Vitamin D's main job, according to the Mayo Clinic, is to help our bodies normalizeblood levels of phosphorus and calcium to maintain strong bones. And from previous observational evidence, doctors have found a connection between having lower levels of vitamin D and a higher risk of certain diseases. But,thequestion that initiated these randomized trials was to find our whether or not this is a"cause-and-effect relationship," and if vitamin D supplements can actually lower our risk of developing these certain diseases.
Researchers looked at 290 prospective observational studies and 172 randomized trials; their findings could not confirm that high vitamin D levels reduce the risk of cardiovascular disease, colorectal cancer and diabetes.
