H, please read his whole post before replying. He stated he switched to citrate awhile back.
Also, muscle twitching, although it can be a sign of magnesium deficiency, can also be a sign of deficiency in some other mineral.
There are other posts elsewhere online where people with adrenal fatigue (which I'm guessing H is not one of) need to go very slowly with magnesium increases, or risk muscle weakness.
