A recent literature review on vitamin D and mood written by Alan Gaby, MD, starts out with this sentence:

The hallmark clue to vitamin D deficiency disease is an associated seasonal and latitudinal variability in incidence and morbidity. Multiple sclerosis, almost absent close to the equator, increases in frequency the further from the equator one lives. Heart disease is worse in the dark, winter months, with blood pressure increasing as vitamin D stores in the body decrease.

On March 16^th 2015, the Journal of the American Medical Association published a meta-analysis of human trials on vitamin D and blood pressure. Their finding: vitamin D does not lower blood pressure ¹.
