Vitamin D – might be a prime defender against the seasonal flu.

Medical professionals have always stressed the importance of vitamins for cold prevention, but new research out of Japan, published in the American Journal of Clinical Nutrition, suggests that a particular one – vitamin D – might be a prime defender against the seasonal flu:

“This study suggests that vitamin D3 supplementationduring the winter may reduce the incidence of influenza A, especiallyin specific subgroups of schoolchildren.”

Researchers followed nearly 350 school-aged children for four months, giving half vitamin D3 supplements and the other half a placebo. Guess what? Those taking the additional vitamin D3 had fewer instances of the flu.

And children who already had low levels of vitamin D – most commonly found in fish and milk fortified with the vitamin – and took the supplements provided by researchers had “a 74 per cent reduction in the incidence of flu”.
