MrsD's Magnesium thread is priceless!
......the oil thing sounds too complicated for my simplistic brain.....

guess I'll just go with the good ol' epsom salts........cows lick salt blocks.... I guess they are pretty intelligent after all
I went to Walgreens today and sure enough the magnesium tablets they offer have 'oxide' written in small print on the back label.
Gonna read the Magnesium thread now.....
Thanks all
