Vitamin D is a flu fighter | WHAT REALLY HAPPENED


Vitamin D is a flu fighter

Now Japanese researchers offer tangible support for that idea. They show that vitamin D supplementation dramatically cut the incidence of seasonal flu among the children they followed.

Their double-blind, placebo-controlled trial was small. Only 334 children completed a three-month course of six pills per day — a dropout rate of almost one-quarter. Then again, that’s a lot of pills to make kids take each day to get just 1,200 international units of the vitamin. (Especially since the teeny capsule I down contains almost twice that much.)

But the supplementation certainly looked promising. Incidence of influenza A was 10.8 percent among the 167 kids who received vitamin D pills. That's in contrast to a flu rate of 18.6 percent among an equal number of children getting identical looking inert pills.
