TJ Clarke Colloidal Minerals

T J Clark’s Colloidal Mineral Formula is a liquid extract of mineral compounds derived from humic shale deposits that are naturally rich in a number of trace elements. Humic shale extracts (plant deposits) predominantly contain sulphates of iron and aluminium, along with traces of colloidal mineral hydroxides. The term colloidal mineral is derived from the presence of colloidal metal hydroxides in these preparations; however, many of the minerals are present in ionic forms.
