Vitamin D is starting to sound like modern day snake oil. It cures everything, just keep buying and taking megadoses forever. It's a steroid hormone that increases calcium uptake. Calcium acts as a stimulant so it only makes me restless and angry and disturbs sleep, kind of like caffeine, and I live near the arctic. Elevated calcium levels also contribute to kidney stone formation.
