Magnesium is a chemical element; it has symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and almost always has an oxidation state of +2.
Magnesium is an essential nutrient. Usually in lower dosages, magnesium is commonly included in dietary mineral preparations, including many multivitamin preparations. Chelated magnesium is sometimes used to aid in absorption.
If you have a magnesium deficiency, a supplement may help. Learn the 10 types of magnesium — and what to use each for.
Magnesium ( /mæɡˈniːziəm/ mag-NEE-zee-əm) is a chemical element. It has the symbol Mg , atomic number 12 and common oxidation state +2. It is an alkaline earth metal and the eighth most abundant element in the Earth's crust .
Magnesium deficiency is an electrolyte disturbance in which there is a low level of magnesium in the body. [3] Symptoms include tremor, poor coordination, muscle spasms, loss of appetite, personality changes, and nystagmus. [1] [2] Complications may include seizures or cardiac arrest such as from torsade de pointes. [1]
magnesium (Mg), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table, and the lightest structural metal. Its compounds are widely used in construction and medicine, and magnesium is one of the elements essential to all cellular life.
Magnesium is the fourth most abundant mineral in your body. It’s involved in over 600 cellular reactions, from making DNA to helping your muscles contract (1). Despite its importance, up to 68%...
Magnesium overview for health professionals. Research health effects, dosing, sources, deficiency symptoms, side effects, and interactions here.
Magnesium occurs typically as the Mg 2+ ion. It is an essential mineral nutrient (i.e., element) for life [1][2][3][4] and is present in every cell type in every organism. For example, adenosine triphosphate (ATP), the main source of energy in cells, must bind to a magnesium ion in order to be biologically active.
Magnesium compounds are compounds formed by the element magnesium (Mg). These compounds are important to industry and biology, including magnesium carbonate, magnesium chloride, magnesium citrate, magnesium hydroxide (milk of magnesia), magnesium oxide, magnesium sulfate, and magnesium sulfate heptahydrate (Epsom salts).
