There is compelling evidence vitamin D helps prevent colds & flu
A large global study has shown that colds and flu can be prevented with vitamin D.
Colds and flu can be very debilitating and sometimes even deadly. Recent research points to vitamin D as being among natural remedies such as vitamin C and garlic which seem to help prevent colds and flu.
There is compelling evidence that vitamin D helps to prevent acute respiratory infections including colds and flu
University of Queen Mary London has reported that there is compelling evidence that vitamin D helps to prevent acute respiratory infections including colds and flu. This finding could have a major impact on public health policy with considerations of fortification of foods with vitamin D.
This study has offered the first definitive evidence that vitamin D protects against respiratory infections
Researchers investigated data from about 11,000 participants who took part in clinical trials in 14 countries which included the USA, UK, India, Japan, Canada, Italy, Australia, Belgium, and Afghanistan. Lead researcher Professor Adrian Martineau from QMUL has commented that this study has offered the first definitive evidence that vitamin D protects against respiratory infections.
Martineau has gone on to say the protective effects of supplementation with vitamin D are most powerful in those people who have the lowest vitamin D levels. Also vitamin D supplementation was observed to work best when given daily or weekly instead of in more widely spaced doses.
Vitamin D is known as the sunshine vitamin
Vitamin D is known as the sunshine vitamin. Protection against respiratory infections with vitamin D seems to work by
increasing levels of antimicrobial peptides, which are natural antibiotic-like substances, in the lungs.
Interestingly colds and flu are most common in the winter and spring when the levels of vitamin D are at their lowest.
BMJ has published this study. Vitamin D supplementation has been found to overall protect against acute respiratory tract infection. The most benefit was seen in those who were very vitamin D deficient. In view of the fact that acute respiratory tract infections are a primary cause of global morbidity and mortality this study is significant. It seems prudent to consider vitamin D supplementation for those at risk.
