in winter people’s vitamin d levels go down anyway and every doctor and scientist knows that
its another reason why people get the flu and die from it
no one has ever made a peep about it despite knowing it
if you dont normally go outdoors or its winter supplement your vitamin d with a quality d3 vitamin
I just started vit-D3 last fall when I had bloodwork and it showed low levels. 1000 IU’S a day. plus 1020 IU’s in multi-vitamine tab. But one does wonder how much is too much.
Vitamin D for influenza

Last paragraph from link:
A colleague of mine and I have introduced vitamin D at doses that have achieved greater than 100 nmol/L in most of our patients for the past number of years, and we now see very few patients in our clinics with the flu or influenzalike illness. In those patients who do have influenza, we have treated them with the vitamin D hammer, as coined by my colleague. This is a 1-time 50 000 IU dose of vitamin D3 or 10 000 IU 3 times daily for 2 to 3 days. The results are dramatic, with complete resolution of symptoms in 48 to 72 hours. One-time doses of vitamin D at this level have been used safely and have never been shown to be toxic.8 We urgently need a study of this intervention. The cost of vitamin D is about a penny for 1000 IU, so this treatment costs less than a dollar.
