How are minerals categorized?

Michael T. Murray, ND
Naturopathic Medicine
Minerals are classified into two categories: major and minor. This classification is determined by the amount of the mineral needed by the body, not by how essential it is for good health. If a mineral is required at a level greater than 100 mg per day, it is considered to be a major mineral.

Major Minerals:
  • Calcium
  • Phosphorus
  • Potassium
  • Sulfur
  • Sodium
  • Chloride
  • Magnesium
Minor (Trace)Minerals:
  • Zinc
  • Iron
  • Manganese
  • Copper
  • Boron
  • Silicon
  • Molybdenum
  • Vanadium
  • Chromium
  • Selenium
  • Iodine
