Something that concerns me about the citrates is possibly increased lead/aluminum absorption:

Anybody have thoughts there? The studies are overall mixed, so it may not be a true issue. Still... wondering if it's the ideal type of magnesium to use.
I am glad for your post, it has been bugging me why I test high for aluminum. Aluminum, I couldn't figure it out. Needless to say, I use a lot of magnesium citrate. I supplement maybe 100% plus of the daily value for magnesium.
I am in the 80th percentile for aluminum, 42nd percentile for lead, and 85th percentile for mercury. I wonder if mercury absorption is also increased by citrate. I did eat a lot of canned tuna, so I was not so perplexed by the mercury number. (Inductively coupled plasma/mass spectroscopy tests by Metametrix).
