96.2% of my body weight comes from "organic elements" present in many
different forms. DNA, RNA proteins, lipids and sugars are all composed of
primarily O, C, H and N. Also, Water (H2O) and carbon
dioxide (CO2)as well as other small molecules involve these elements.

Oxygen (65.0%)
Carbon (18.5%)
Hydogen (9.5%)
Nitrogen (3.2%)

3.9% of my body weight comes from elements present in the form of salts.

Calcium (1.5%)
Phosphorus (1.0%)
Potassium (0.4%)
Sulfur (0.3%)
Sodium (0.2%
Chlorine (0.2%)
Magnesium (0.1%)
Iodine (0.1%)
Iron (0.1%)

The trace elements compose less than 0.5% of total body weight but then
again, they are essential for homeostasis. Some of these elements are
cofactors of critical enzymes in the body.
