In the first study, the mortality rate due to viral respiratory tract infection was nearly 100% when vitamin D levels were below 19 ng/ml.4 At 25 ng/ml the death rate was still high at 85% but started dropping rapidly, and by the level of 34 ng/ml there was a 0% mortality rate. This study showed the target for increasing survival when dealing with a respiratory virus is a blood level of 25-OH-D3 of at least 34 ng/ml is critical.
In the second study, a blood level of 25-OH-D3 less than 20 ng/ml on admission to hospital in Belgium was associated with a 3.7-fold increase in the odds of dying from a viral respiratory infection. Overall 59% of the patients admitted for a viral upper respiratory tract infection were vitamin D deficient on admission: 47% of females and 67% of males.
A search of ClinicalTrials.gov reveals there are currently close to 40 ongoing clinical trials looking at vitamin D3 in respiratory tract infections around the world.
