It's made a difference in mine. I started the Mg about a month ago, I think. It can take some time for it to correct, so give it a chance.

I'm using both internal (Mg citrate capsules) and external (transdermal Mg sulfate). I have experienced that rubbing the transdermal into problem spots helps.

I just hadn't thought much about the Ca aspect before seeing that little mention of it in the article.
