Seem to work for my wife
I don't know much about these Magnesium Malate 1000Mg tabs in the 180 count bottles.  But my wife seems to value them quite a bit.  I have been ordering them for her for many months and she takes them almost religiously.  They always seem to come sooner than estimated by the seller, which is definitely an added bonus.  They seem to aid the functioning of several organ systems and do not upset my wife's stomach at all.  So we will keep ordering them.  These seem to be the best for her.
