I don't know...I am not using the DE anymore. I am going to put it directly into the trashcan.
1100 ppm of Al is not healthy for me or my beloved pets. People selling thier products will tell you otherwise.
I consulted a couple biologists and chemical bioligists at work, they all made a face or an uh-oh expression at that amount of aluminum in something that would be intended for consuming, and none of them said they'd take it themselves,
Silica is found in many other sources, this just isn't for me.
Maybe I will save it to pour on ants or something.
Live and learn!
I did find I was very very tired after the few days of taking it, reminded me of when I was anemic.
