The core of the Earth contains an inner layer, an
iron -
rich solid ball, and an outer layer, of
liquid iron and nickel, with a mantle of silicate.
In that case, up your intake of
iron -
rich plant sources, cook in cast
iron pots (especially acidic solutions like tomato sauce, orange juice), avoid drinking any type of tea or coffee at meals, take citrus or vitamin C with
iron -
rich meals, or consider a modest amount of a
liquid - based
iron elixir (e.g. a couple drops per day).
