If there was one thing if asked, what would be the best thing a person could do, that would protect you from this virus, colds or flu’s of today. I would say start taking a vitamin D 3 1000 IU tablet a day. I would bet that if everyone in Canada had their level checked with a blood test, everyone would find they are well below what is needed to stay healthy. Even for myself being outside all summer, when I had mine checked, I was only at 40%. The reason for this is that most folks work inside, sitting at a computer more than they should be. I know some haven’t got a choice in the matter, but you do have a choice in taking a vitamin D3 Tablet every day. What have you got to lose? A lot more if you don’t.
