Vitamin D3 costs almost nothing, it's beneficial for many things and there's no harm in taking it in order to ward off pneumonia, which is most likely to kill in a Covid infection. So, why not? I don't understand why people react to recommendations to take an over the counter Vitamin D supplement the same way they would to the 'healing' power of crystals.
I swear by vitamin D. I used to get sick quite often and once I started working closely with the public I knew I needed to do something. Now every morning I take one or two vitamin D and I wash them down with Emergen-C. Don’t get sick hardly at all anymore and if I do it’s not that bad. Hope I didn’t just jinx myself!!!
