that you should eat at least one small rock per day. Quote: “rocks are
a vital source of minerals and vitamins that are important for
digestive health”.

Who needs teeth, anyway? Or maybe put them in a rock crusher first?
Bit of concentrated acid to dissolve those minerals? (Wonder what it
will do to the vitamins?) Or make a colloidal suspension in your
favourite smoothie?
