Manganese designated by the symbol Mn . It has the atomic number 25. It is found as a free element in nature (often in combination with iron), and in many minerals. Manganese, a trace mineral that participates in many enzyme systems in the body, was first considered an essential nutrient in 1931. Researchers discovered that experimental animals fed a diet deficient in manganese demonstrated poor growth and impaired reproduction. Manganese is found widely in nature, but occurs only in trace amounts in human tissues. The human body contains a total of 15-20 milligrams of manganese, most of which is located in the bones, with the remainder found in the kidneys, liver, pancreas, pituitary glands, and adrenal glands. Manganese activates the enzymes responsible for the utilization of several key nutrients including biotin, thiamin, ascorbic acid, and choline. It is a catalyst in the synthesis of fatty acids and cholesterol, facilitates protein and carbohydrate metabolism, and may al...

Magnesium   is a chemical element with the symbol Mg , atomic number 12, and common oxidation number +2. It is an alkaline earth metal and the eighth most abundant element in the Earth's crust , where it constitutes about 2% by mass, and ninth in the known universe as a whole. Magnesium is the fourth most abundant mineral in the human body and is essential to good health. In our bones we have around 50% of total body magnesium but in our blood we have only 1% of magnesium. It's a small part but very important for people's health. Magnesium is needed for more than 300 biochemical reactions in the body. Magnesium helps people in many ways - regulate blood sugar level, keeps the heart rhythm and immune system and keeps bones strong. There is one really interesting role of magnesium - to manage disorders such as hypertension, disease, and diabetes. Sometimes we called the magnesium "macromineral," which means that our food must provide us with hundreds of m...
