According to researchers in England, only one in ten people who were encouraged to spend more time outside on sunny days caught the flu, compared with one in five who received VIT D supplements in tablet form. Mitsuyoshi Urashima, the Japanese doctor who led the study, said that vitamin D has proven even more effective than vaccines to prevent flu!
Vitamin D has been shown to be more beneficial for this purpose to confront the results with statistics from the study who received no supplements of vitamin D. Sun exposure reduced risk of influenza disease by one third of the initial weight.
Using vitamin D in preventive or therapeutic purposes is not uncommon in medical terms. Dr. John Cannell recommended that higher doses of vitamin D (50,000 IU) for three days starting at the first sign of a cold or flu. Vitamin D acts as a natural antibiotic, and is effective against all types of germs (viral, bacterial, fungal and parasitic organisms).
Vitamin D deficiency is a very common problem during the cold season, especially in countries north of the equator. It is a shame, because, inter alia, vitamin D stimulates the production of antimicrobial peptides in the white cells and epithelial cells lining the respiratory tract, the infection protecting lungs.
Japanese study supports the theory that low serum levels of vitamin D in winter is closely related to the outbreak of influenza epidemics especially between December and March.
Dr. John Oxford, Professor of Virology at Queen Mary School of Medicine in London, said: "This is a timely study that will surely capture the attention of scientists. Folds perfectly seasonal flu pattern. There is growing evidence that tangible support that hypothesis on the potential of vitamin D. "
Also, researchers have identified the exact mechanism by which vitamin D strengthens the immune system and why it plays such an important role in our health. As already pointed out above, vitamin D is not a vitamin in the true sense of the word, but a steroid hormone precursor that has far-reaching effects on innate immunity.
