Some people refer to them as elements instead of minerals, and the names can be used interchangeably. However, in the nutrition community, they are more commonly referred to as minerals. Minerals can be divided up into three different categories:
- Macrominerals
- Trace Minerals (aka Microminerals)
- Ultratrace Minerals
There is not an exact, agreed on definition for how the different categories are defined, but in general they are defined by the amount required and found in the body such that:
Macrominerals > Trace Minerals > Ultratrace Minerals
Macrominerals | Trace Minerals | Ultratrace Minerals |
---|---|---|
Calcium (\(\ce{Ca}\)) | Chromium (\(\ce{Cr}\)) | Arsenic (\(\ce{As}\)) |
Chloride (\(\ce{Cl}\))a | Copper (\(\ce{Cu}\)) | Boron (\(\ce{B}\)) |
Magnesium (\(\ce{Mg}\)) | Fluoride (\(\ce{F}\)) | Nickel (\(\ce{Ni}\)) |
Phosphorus (\(\ce{P}\))b | Iodine (\(\ce{I}\)) | Silicon (\(\ce{Si}\)) |
Potassium (\(\ce{K}\)) | Iron (\(\ce{Fe}\)) | Vanadium (\(\ce{V}\)) |
Sodium (\(\ce{Na}\)) | Manganese (\(\ce{Mn}\)) | |
Molybdenum (\(\ce{Mo}\)) | ||
Selenium (\(\ce{Se}\)) | ||
Zinc (\(\ce{Zn}\)) |
a Chlorine ion, Cl-
b Phosphate in body, PO4
The table below shows the estimated amount of the macrominerals, trace minerals, and ultratrace minerals found in the body.
Macrominerals | Trace Minerals | Ultratrace Minerals | |||
---|---|---|---|---|---|
Calcium | 1200 g | Iron | 4 g | Silicon | 1 g |
Phosphorus | 780 g | Fluoride | 3-6 g | Boron | 17 mg |
Potassium | 110-140 g | Zinc | 2.3 g | Nickel | 15 mg |
Sodium | 100 g | Copper | 70 mg | Arsenic | 7 mg |
Chloride | 95 g | Selenium | 14 mg | Vanadium | 0.1 mg |
Magnesium | 25 g | Manganese | 12 mg | ||
Iodine | 10-20 mg | ||||
Molybdenum | 5 mg | ||||
Chromium | 1-2 mg |
The figure below shows the distribution of minerals in the periodic table, which you should be familiar with from your chemistry education.
