Vitamin D also works for me. I was deficient in vitamin D and didn't know it till I got tested for vitamin D deficiency.
I had bad cramps also. They're much better now. Good luck😀

Try magnesium (and calcium) supplements for legs that cramp. It works for me!

I am a RN & used to get terrible body cramps after working several 12 hour shifts in a row. They start in my toes & progress up my body. The only thing that works for me is pickle juice. About 3/4 cup usually gets them to subside almost instantly. I am no longer working the long hard shifts in a hospital but still occasionally get the cramps during the night.
I ask my local grocery store deli for pickle juice & they give me a large container @ no charge.

I take vit D, Calcium/magnesium, drink lots of water. I have no problem walking. The cramps last minutes. If they last long enough and r bad enough, I’m very sore at that location the next day.
I’m going to try Vit E.

I just recently got a bad cramp in my thigh that lasted hours seems like. Went to Er and they found nothing of course! I don't know why it did it but I do not want it to come back.
