Discovered as a new element by Barnard Courtois in 1811, knowledge of this substance has come to include the plethora of benefits it brings to the body as an essential nutrient. For many years, getting enough iodine in the diet through natural means was difficult in many geographic regions, and remains so for a high percentage of the world's population in developing nations. With the advent of iodized salt, meeting the daily iodine requirement became nearly effortless and inexpensive in the industrialized regions. In these first world countries, iodine deficiency is now rare. As developing nations are able to make the shift to iodized salt, their rates of iodine deficiency and the diseases associated with it have also begun to decline.

The mineral iron is essential to the health and functioning of the body. One of the most important properties of iron is its role in oxygenating the blood. Another essential action of iron is energy metabolism. It is a factor of the neurodevelopment of infants as they grow and develop in the uterus. Iron serves to promote the proper functioning of the immune system, particularly in the production of white blood cells. The body also needs iron in order to make proper use of the B vitamins.

Recently, more value of the trace mineral selenium in regards to huamn health has come to light. Current studies indicate this mineral can play an important role in protecting the body from serious disease and illness.

There have been a number of publications reporting studies showing that breathing nitrous oxide may destroy a person's vitamin B12.

What first came to my mind was the use of this gas by dentists. Nitrous oxide, often called "laughing gas," is commonly used by dentists to help mitigate pain.

Vitamins are essential to the proper function and health of the body. While many vitamins serve individual purposes, the more common way for vitamins to function is in conjunction with other vitamins, minerals, or nutrients, such as enzymes.

Manganese is a metallic mineral discovered by a 17th century German chemist named Johann Glauber. It was not isolated in a pure form until 1774, by Johan Gahn. But it was Gahn's associate, a Swedish chemist named Carl Scheele, who first determined that manganese was an element. Manganese, as a trace mineral element, is found in all forms and walks of life. It is essential to the health and functioning of the human body and human mind in several ways.
