Highlights of Report in Swedish translated by Google
- Peter Bergman and his colleagues are fortunate to have 140 patients in daily treatment for one year with either vitamin D (4000 IU) or a placebo.
- The study was double-blind: neither the patients - all of which were susceptible to infections - nor caregivers knew who belonged to which group before the trial was over.
- The results show that vitamin D reduced patient discomfort.
- The probability of requiring treatment with antibiotics during the study period was 63 % lower in the vitamin D group compared with the placebo group, and the incidence of fungal infections, including respiratory, decreased.
Chart from 2015 publication
Note: if takes ~100 days for the vitamin D levels to plateau (thus, no benefit is expected until then)
Respiratory tract infection eliminated in 36 percent of people
Types of Respiratory Infections
Vitamin D did particularly well with
- Moraxella catharralis
- Staphylococcus aureus
- Pseudomona aeruginosa
- Fungal infection
Adverse effects: fewer with vitamin D than with placebo
Suspect that Vitamin D caused the reduction in:

- Cardiovascular
- Infections

Has a chart showing a very strong relationship with season of low Vitamin D at 30 degrees North latitude in China
Note RTI in Middle East peaks in the summer, not winter, because they stay away from the hot hot sun.
