I´ve been asking google and I didn´t really get a result. I am wondering about my muscle cramping lately. I´m having multi vitamins, calcium and magnesium extra and never together and still I am having these moments when leg muscles or toe muscles start cramping and in a brighter moment I realized that this could mean that my body doesn´t pick up what I deliver. Are there any blood tests whom would bring such proof or what enzyme is responsible to fit in these minerals? I am somewhat puzzled.
duh...
later,
