More than two dozen studies of Covid-19 show us the way to TURN BACK the Second Wave.

Vitamin D versus Covid-19

These 27 studies show that having normal blood levels of vitamin D reduces Covid-19 risks:
* vitamin D reduces risk of infection [7, 8, 9, 11, 12, 14, 16, 23, 27]
* vitamin D reduces risk of having a severe case [1, 3, 4, 5, 15, 17, 20, 22, 24, 25, 26]
* vitamin D reduces risk of hospitalization, ICU care, or mechanical ventilation [2, 10, 14, 15, 21, 22, 24, 26]
* vitamin D reduces risk of dying from Covid-19 [4, 6, 7, 9, 12, 13, 17, 18, 19, 22, 24, 25]

And all you need to get those benefits is a normal blood level of vitamin D:
30 to 100 ng/ml, which is the same as 75 to 250 nmol/liter.

Note, however…
