Minerals comprise all natural, inorganic substances and, by definition, are not "manmade." Furthermore, if something is not man-made one can assume it "occurs in the earths crust". You are essentially asking for the name of any mineral.
The nutritional minerals in the human body include calcium, phosphorus, sulfur, potassium, chlorine, sodium, magnesium, iron, fluorine, zinc, copper, manganese, iodine, cobalt, selenium, chromium, and molybdenum.
Any of the elements with atomic numbers between 1-Hydrogen and 92-Uranium (excluding 43-Technetium) occur naturally in the Earth's crust.
Elemental abundance in the Earth's crust:
Oxygen: 49.5%
Silicon: 25.7%
Aluminum: 7.5%
Iron: 4.7%
Calcium: 3.4%
86 Other Elements: 9.2%
Elemental abundance in the human body:
Oxygen: 65%
Carbon: 18%
Hydrogen: 10%
Nitrogen: 3%
20 Other Elements: 4%
