Japanese doctors have found that the prevalence of flu in children can be reduced if they take vitamin D. According to a research in the American Journal of Clinical Nutrition, vitamin D, which is naturally produced by the body when exposed to sunlight, can be more effective than anti-viral drugs or vaccines, without causing any side effects.
In a clinical trial, only one in ten children taking vitamin D came down with the flu when compared to one in five given anti-viral drug. Mitsuyoshi Urashima, the Japanese doctor who led the trial concluded that the sunshine vitamin was more effective than vaccines when it comes to preventing the flu.
It has been found that vitamin D has even more effect when the comparison excluded children who were already taking vitamin D outside the trial. It was then shown that vitamin D lowered the risk of flu to a third of what it would otherwise be.
According to Dr. Damien Downing, a doctor, and medical consultant, epidemics are profitable for the government. Consequently, he advises patients to boost their vitamin D intake instead of getting the vaccine.
There are doctors in Canada and the U.S who prescribe 50,000 IU of vitamin D on a daily basis as treatment for various chronic diseases.
Vitamin D works similarly to antibiotics and it fights off every type of microbes, such as fungi, bacteria, and viruses. Dr. John Cannell, MD, suggests high-dose vitamin D (50,000 IU) be consumed for 3 consecutive days at the first sign of a cold or the flu. In a case of an infection, you will need to take more of it.
The sunshine vitamin acts as an immune modulator, increasing macrophage activity and preventing excessive production of inflammatory cytokines. It also protects the lungs from an infection, by stimulating the production of powerful anti-microbial peptides in the epithelial cells lining the respiratory tract.
50 Percent Reduction In Flu Infections Using Vitamin D
The trial done by doctors and scientists from Jikei University School of Medicine in Tokyo, Japan involved 354 children. It was found that vitamin D protects against influenza A but not against influenza B, which is less common.
The children were given 1200 IUs of vitamin D on a daily basis over the course of three months. In the first month the prevalence of flu was the same in the both groups while by the second month, the advantage of the vitamin became clear.
As reported in the American Journal of Clinical Nutrition, zanamivir and oseltamivir, commonly used anti-viral drugs, reduce risk of flu infection by 8% in children who have been exposed to infection. On the other hand, vitamin D reduces the risk by up to 50%.
It is important to mention that anti-virals are expensive and potentially toxic, so taking them is definitely not worth it. Vitamin D, on the other hand, provides many health benefits, such as preventing bone loss and reducing the risk of viral infections, heart disease, diabetes, cancer, etc.
The Japanese finding basically supports the theory that low levels of vitamin D in winter are the reason why flu epidemics peak during the winter months.
According to Dr John Oxford, professor of virology at Queen Mary School of Medicine, London, “This is a timely study. It will be noticed by scientists. It fits in with the seasonal pattern of flu. There is an increasing background of solid science that makes the vitamin D story credible. ”
Dose and Vitamin D Levels Are Critical
Vitamin D is a steroid hormone precursor which has tremendous impact on innate immunity
The amount of vitamin D in food and multivitamins is trivial
The correct daily dose of vitamin D for adults is approximately 5,000 IU/day, not the 200 to 600 IU recommended by the Institute of Medicine, the National Institutes of Medicine and the FDA.
The 1,25-di-hydroxy-vitamin D test many physicians now order is not the right test to determine vitamin D adequacy. It`s the a 25-hydroxy-vitamin D!
Healthy vitamin D blood levels are between 70 and 90 ng/ml, levels obtained by fewer than 5% of Americans.
Pharmaceutical doses of vitamin D (1,000 IU per pound of body weight daily for several days) will effectively treat not only influenza and the common cold, but help treat other seasonal infections, such as pneumonia, meningitis, and septicemia, in both children and adults.
