Many people are vitamin D-deficient because there are only small amounts in food, Holick said. Most vitamin D comes from sun exposure and many are deprived, especially during winter months.

Which explain why it (and the common flu) flares up in the cold winter months. People need their Vitamin D and from about November to February, the sun just isn't high enough in the sky in most U.S. latitudes to be a factor.

There are foods high in Vitamin D such as eggs (with the yolks), fatty fish like sardines, and beef liver. But people have been brainwashed into avoiding these incredibly nutritious foods.

Even though I eat those foods regularly, I still take 2,000 to 5,000 IUs of Vitamin D in pill form (less in summer when I am getting sun).

Many articles posted here about the benefits of Vitamin D but it can't be posted enough times.

I’ve been taking atleast 2,000 IU’s per day since this Covid mess showed up and vitamin reports came out quickly. 1,000mg of Vit C, 2,000 - 4,000 IU’s of VitD3, and I was taking some Magnesium in powder form at night.
