Primarily hemoglobin which is derived from the mineral Iron. Iron however works in conjunction with dozens of other minerals and supplementation must include as many of it's co-factors as possible.
iron
It is an iron-based protein called hemoglobin.
transportation of oxygen in the blood stream
red blood cells
The red blood cells carry the oxygen in blood.
The molecule of the protein haemoglobin has at its centre an atom of iron, as the central part of the molecule is an iron complex. This is why you need the mineral iron in your diet. Without sufficient iron in the diet the oxygen carrying capacity of the blood is lowered, and you will soon become anaemic.
Iron
There are three main constituents of blood. There are red blood cells that are responsible for the transportation of oxygen, white blood cells that are the body's defense against illness, and plasma which transports lymphocytes.
Red blood cells are responsible for oxygen exchange
No, as the red blood cells carry oxygen [O2] to the tissues of the body, and return carbon dioxide [CO2] to the lungs for removal from the body when exhaling. Without the red blood cells, the cells of the body will die.
Blood - a fluid connective "tissue" - is the primary transport medium of substances, such as oxygen and nutrients, in the body.
calcium
The hemoglobin in red blood cells carries oxygen.
iron
Blood. Oxygen is transferred throughout the body by blood. Hemoglobin in the blood carry the oxygen through the body and distributes it.
phosphorus
Blood is responsible for carrying nutrients and oxygen to your cells. Also a way to dump out waste from the cells.
