I’ve been taking Vitamin D supplements for over ten years. Have never been sick since. Not even a common cold. I commute to NYC every day on a train with hacking, sneezing unhealthy looking people but none of those germs make me sick.

Ditto.

I would get bronchitis at least once per year before taking Vitamin D. In the 10 years since I've been taking Vitamin D suppliments I got bronchitis once on a Christmas flight from LA.

I take 10,000 of D3 daily split into two 5000 doses. I was constantly coming down with colds. I can’t say such episodes have dropped to zero, but much, much reduced compared to pre-D3 time frame.

Yup...that's my story as well.

I did get the flu a few years ago...

My case was very, very mild and over in two days, everybody else was sick for weeks and almost bedridden...

Makes sense, as vitals D benefits the immune system and deficiency has been linked to autoimmune didorders.

Did you get sick prior to taking the supplement?

I catch everything. My entire family is that way. I guess you largely inherit your immune system.
