Too Much Vitamin D Harmful

Thursday, 31 May 2012 12:53 PM

Vitamin D deficiency is common and raises the risk of a host of health problems. But new research has also found that too much of the “sunshine vitamin” can also be unhealthy and pose dangers.
The study, conducted by the University of Copenhagen, shows high levels of vitamin D in the blood are associated with an increased risk of death. The findings, published in the Journal of Clinical Endocrinology and Metabolism, are based on an analysis of blood samples from 247,574 Copenhageners.
"We have had access to blood tests from a quarter of a million Copenhageners. We found higher mortality in people with a low level of vitamin D in their blood, but to our surprise, we also found it in people with a high level of vitamin D,” said lead researcher Dr. Darshana Durup. “We can draw a graph showing that perhaps it is harmful with too little and too much vitamin D."
Vitamin D helps calcium build bones, reducing the risk from falls and broken hips. It also combats heart disease, depression and certain types of cancers. Too little vitamin D in the blood – less 10 nanomol per liter of serum – raises health risks by 2.31 times, the new study found. But they also determined too much vitamin D -- more than 140 nanomol – raises mortality risks by 1.42 times.
Durup said scientists do not know the cause of the higher mortality, but noted the new results question the notion that you can never get too much vitamin D.
"A lot of research has been conducted on the risk of vitamin D deficiency,” she said. “However, there is no scientific evidence for a 'more is better' argument for vitamin D, and our study does not support the argument either.”
