Frequently asked questions
Minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids. There are two types of minerals: macrominerals, such as calcium and magnesium, which are needed in larger amounts, whilst trace minerals are needed in very small amounts. Trace minerals include iron, zinc and selenium.
Minerals are an essential part of our diet, as they play a number of important roles in the body. The mineral calcium is important as it plays a key structural role in our bones and teeth. The body uses iron to make haemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body. Magnesium is an essential mineral that is involved in over 300 biochemical processes within the body.
