Six macrominerals are required by people in gram amounts.
Daily requirements range from 0.3 to 2.0 g. Bone, muscle, heart, and brain function depend on these macrominerals.

Dietary guidelines for trace minerals have been determined (see table Guidelines for Daily Intake of Trace Minerals Guidelines for Daily Intake of Trace Minerals Six macrominerals are required by people in gram amounts.

All trace minerals are toxic at high levels; some minerals (arsenic, nickel, and chromium) may be carcinogens. It is not clear whether chromium should be considered an essential (required) trace element (1 Reference Six macrominerals are required by people in gram amounts.

Trace mineral deficiencies (except for iodine, iron, and zinc) do not often develop spontaneously in adults on ordinary diets; infants are more vulnerable because their growth is rapid and intake varies. Trace mineral imbalances can result from hereditary disorders (eg, hemochromatosis Hereditary Hemochromatosis Hereditary hemochromatosis is a genetic disorder characterized by excessive iron (Fe) accumulation that results in tissue damage. Manifestations can include systemic symptoms, liver disorders... read more
