Re: Re: transdermal Mg..... re apositive controlled trial of IM Mag

[Guest guest]

I wonder: if mag causes just loose stools or mild diarrhea, would one be better off taking the mag and getting a mild case of intestinal content rushing through us a bit faster than is normal rather than not supplementing at all and maybe being constantly very low in mag?

In other words, would mild intestinal upset cause worse depletion of a number of nutrients and drugs than the mag depletion I might be living with?

BTW I have not noticed mag-rich foods upsetting my gut, just supplements.

You can get tested for magnesium levels; if they're normal, there's no

need to put yourself through the unpleasantness of taking magnesium

supplements. But if you are deficient, then yes, correcting it is more

important than avoiding loose stools. Also, the gut adapts to a lot of

things; it might adapt to magnesium supplements. (There's no way of

adapting to osmotic-laxative-size doses, but the doses necessary for

nutritional purposes are lower than that.)
