Hey Liza,
Not sure if its applicable here. I had cramps and twitchng and vibrations. I think it was related to multiple things.
I did find out that some of my muscle cramps were due to iron deficient anemia. I take Repliva for it and once my iron levels improved so did the muscle cramps.
I also add in magnesium since my insulsin resistacne meds deplete it. I use mag glycinate which is supposed to be highly absorbable.
Hope that helps.
