What is the chemical composition of the human body by
element and %?
Dry weight %
Trace amounts of B, F Si, V, Cr, Mn, Fe, Co, Cu, Zn, Se, Mo, Sn, I.
There are some arguments as to the importance of other trace elements. If
you happen to know a farmer with cows or cattle, take a look at the
nutritional contents of "calf pellets" and you can see what they think a
calf needs in its diet to be healthy...we are just another mammal.

The chemical composition, by compound, would be extremely long. The
chemical composition, by element, can be found on a number of web sites.
Search with www.google.com
for "elemental composition human body".
The following web site give the most
complete list of elements that I found.
