A recent study by the University of Tampere in Finland has found that vitamin D helps to prevent respiratory infections. In the study, supplementing with vitamin D resulted in more than half the participants who took it staying healthy throughout the trial, compared to just over 30 percent in the control group.
Dr. Ilkka Laaksi and her team evaluated a group of 164 males going into the military to see if vitamin D supplementation affected their overall health. They gave part of the group 400 international units (IU) of vitamin D a day for six months, and the other part of the group a placebo pill for the same period of time. Those who took vitamin D experienced greater overall health and fewer respiratory infections than those who did not.
Though 400 IU of vitamin D a day meets minimal recommended government intake recommendations, many in the medical profession are now realizing that this level is far too low to offer much therapeutic effect. We suspect that if a higher dose had been used in the study, the effects would have been even more significant.
This hypothesis was illustrated in a recent Japanese study that administered 1,200 IU doses of vitamin D to schoolchildren. Those who took this dose every day had a much lower chance of developing influenza than others.
