The Truth Behind Vitamin D3 helping the severity of COVID-19 symptoms.

I am MD Gregor Sklenar from Former Yugoslavia, now Serbia. I am also the Co-chair of health and safety for UPS.
I am predicting a bad winter in January, February, and March. These months will be the worst because of the shorter days– this meaning significantly lower Vitamin D3 levels.
We have to act fast and check our vitamin D levels. God bless you.
