Sorry, sf, I can't because I got a bag of it as a gift.
I did do a search for "magnesium malate" once though and was encouraged about how many people sold it on the Internet. I tried unsuccessfully to find the kind that came from apples (as opposed to a synthetic kind.) Do ask whomever you wish to buy from how they derived it. There is a such thing as malic acid or magnesium malate from apples.
