Trace metal

However, insufficient plasma or tissue levels of certain trace metals can cause pathology, as is the case with iron.

Trace metals within the human body include iron, lithium, zinc, copper, chromium, nickel, cobalt, vanadium, molybdenum, manganese and others.

Human vitamin pills and plant fertilizers can be a source of trace metals.

However, when taken in an excessive amount can cause a disease called "Fluorosis', in which bone deformations and yellowing of teeth are seen.

Roughly 5 grams of iron are present in the human body and is the most abundant trace metal.

The mucosal cells of the digestive tract contain metallothionein proteins that store the zinc ions.
