specifications generally include a minimum
viable cell count of 1 x 10^8 CFU/g or ml, a
specified pH range (often 5.0-7.5), and a
maximum moisture content for powderbased forms. The active ingredients are
beneficial zinc-solubilizing bacteria, and the

shelf life and conformity to standards,
sometimes backed by reports from
accredited labs.
