What it is made of
The full matrix.
Sixty-plus elements.
Nobody manufactures this. It forms over centuries inside sedimentary rock and seeps out in the summer heat. Every seam carries its own geology, so we measure each batch and print the number on the pack.

The contaminant screen
Eight elements screened, none detected
The same assay that reads the mineral matrix also reads what should not be in it. Every element on the panel came back below the reporting limit, and the signed certificate for your batch lists each one by name.
Trace elements inherent to the seam
{{ t }}
Identified by seam analysis, native to the rock rather than added at the factory.
Why the form matters
A mineral in a matrix
is not a mineral in a tablet.
These minerals were never manufactured salts. They formed alongside the fulvic and humic acids that carry them, and leave the seam already bound into fulvate complexes. A different chemical object from magnesium oxide in a tablet, and the literature treats it as one.
Fulvic acid is studied specifically as a chelating carrier: low molecular weight, soluble across the full pH range, and examined for its role in moving ionic minerals across the intestinal wall. Nat Prod Res · 04
