hey, Joe(or shall I call you "stinky"?:)...I don't know.....
I take 400 mg magnesium(citrate) per day. I have yet to order some magnesium chloride.
The io-docs recommend 3-600 mg magnesium...so...1200 mg?
refresh my memory as to why that amount is recommended.
Also, personally, I salt load very rarely, haven't done it in months. And then for obvious manifestation of bromide detox(headache) I do take salt in my drinking water, though, daily...
