In brief: Magnesium Tablets

Magnesium is the relaxation mineral, as compared to calcium, which is the contraction mineral for muscles.
I.V. magnesium starts working immediately. Oral magnesium has to be absorbed in the G.I. tract, which would vary person to person. Keep in mind that it can vary up to 8 fold from person to person how much magnesium a person needs, as well.
