I don't know for sure if it works for the flu, but I do know that since we started supplementing with Vitamin D, we just don't get sick. I have two kids in school (4th and 6th grade) and a wife that volunteers/works at the grade school, and we don't get the bugs that go around. My youngest has had two colds in the last year but they were just sniffles that lasted a couple of days - no fever or missed school. He also didn't get the cough afterwards like he always did before.
