Vitamin D Doses Can Reduce Respiratory Tract Infections

Respiratory Tract Infections (RTI) are a contagious infection of the upper or lower respiratory tract caused by various bacteria and viruses. Upper respiratory tract infections (URTIs) infections include the common cold, laryngitis, acute rhinitis, acute rhinosinusitis, acute otitis media, and tonsillitis. And lower respiratory tract infections (LRTIs) include pneumonia, bronchiolitis, acute bronchitis, and tracheitis. There is a natural remedy that is proven to significantly lower the risk of developing a respiratory tract infection, which is explained as follows.

Researchers from the Karolinska Institute and Karolinska University Hospital in Sweden are reporting this month in the journal BMJ Open on vitamin D and respiratory tract infection. Specifically, that high vitamin D doses given for a period of one year can significantly lower the risk of developing a respiratory tract infection, compared to those who do not take those high doses. Consequently, if there are fewer people with such infections then these people will also require fewer antibiotics.

This is especially meaningful in Scandinavia, where in the winter the residents don't see much sun and therefore don't get good amounts of vitamin D. The ensuing deficiency causes many health problems in that region.

"Our research can have important implications for patients with recurrent infections or a compromised immune defense, such as a lack of antibodies, and can also help to prevent the emerging resistance to antibiotics that come from overuse. On the other hand, there doesn't seem to be anything to support the idea that vitamin D would help otherwise healthy people with normal, temporary respiratory tract infections," said the researchers.

The double-blind randomized controlled trial featured 140 volunteers presenting with symptoms of disease in their respiratory tracts for at least 6 weeks prior to the start of the study. They were randomized into one of two groups: One received a placebo, the other received high-dose vitamin D3 (4000 IU) daily.

The study lasted 12 months and each was asked to keep a health diary. The results were that the vitamin D group had a 25% drop in respiratory tract infection symptoms. Those from this group were able to reduce their use of antibiotics by nearly half. The authors quoted a New Zealand study which was recently published in JAMA in which scientists showed that vitamin D did not reduce the severity or incidence of respiratory tract infections.
