While VitaD deficiency is pervasive, 'me thinks' the author overstates the source article. The "study" is little more than a "review" of other peoples papers. The "study" (aka review) largely sidesteps decades of scientific progress. For instance, one widely-recognized reason for low vitaD is reduced exposure to the sun. More people work indoors. Reduced bright light exposure during the daytime has a cascade of biological consequences which have been mechanistically studied in the laboratory and in populations to establish cause and effect. e.g. Indoor lighting and irregular lighting during the day tend to reduce the strength/amplitude circadian linked hormonal rhythms, that underlie sleep. Special photoreceptor neurons in the eye directly signal daytime function dozens of cortical brain regions. None of this is about VitaD.

While VitaD is part of a bigger day-night pattern of physiological health, and correlates with an office/school anxiety-generating and circadian disturbing trend involving less sun exposure, does promoting VitaD as a "silver bullet" remedy for millions of people seem irresponsible for Toms Guide publication?
