In a study conducted by researchers from the University of Otago, New Zealand, found that those who took vitamin D supplements in high doses every month within a year it is still possible to catch a cold.
Consuming vitamin D supplements did not reduce the healing time, the severity of illness, or lost work time because they have to rest at home. In other words, vitamin D, "not effective to prevent or help cure respiratory infections experienced by men," said Dr. Jeffrey Linder, of Brigham and Women's Hospital in Boston, who commented on the results of this study.
The participants who took the placebo effect, which mostly have high levels of vitamin D in the body also obtain similar results to those who took vitamin D supplements in high levels, are still caught the flu.
Therefore, the researchers stressed that perhaps only those with vitamin D deficiency who may feel the immediate benefit of taking vitamin D such as reduced risk for the flu.
Unfortunately, this research is still in the narrow scope of the population and only a measure consumption only. For that, they need further studies that can clarify whether there are benefits in taking supplements in other populations and with various other doses.
Previous studies showed an association between low levels of vitamin D with an increased risk of a person developing upper tract infections such as tuberculosis (TB). But still did not show that vitamin D can reduce a person's risk of catching the flu.
