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.
Yes, I agree. Vitamin D is a vitamin and calcium is an electrolyte.
Vitamin D deficiency is pretty common these days. It can have an effect on circulating calcium but that usually only occurs at the extremes of vitamin D levels. Glad to hear that your muscle cramp problem resolved.
