One function of Vitamin D is in regulating the uptake of calcium in the gut. The other is to block parathyroid hormone, which facilitates bones taking up calcium. So the vitatmin increases calcium uptake and decreases its use in bone. Net result is an increase in circulating calcium. Calcium is an electrolyte and has a strong effect on muscles and nerves.
I was having cramping in my legs and my doc checked vitamin D levels and they were low. Took supplemental vitamin D. The cramps went away.
