The RDA for Trace Minerals

The following table lists the RDAs for the trace minerals.

Trace Minerals
Recommended Daily Allowance
Mineral RDA
Boron None available
Chromium 50 to 200mcg
Cobalt None available
Copper 1.5 to 3 mg
Iodine 150 mcg
Iron 10 to 15 mg
Manganese 2.5 to 5.o mg
Molybdenum 75 to 250 mcg
Selenium 55 to 70 mcg
Vanadium None available

Many foods that would normally be expected to supply the trace minerals unfortunately do not. Many soils are geographically deficient in certain minerals and therefore foods grown in them lack those nutrients. A similar problem can be caused by over farming or poor soil management.

Many areas are deficient in selenium, a very important trace mineral.
