- n. A light, silvery-white, moderately hard metallic element that in ribbon or powder form burns with a brilliant white flame. It is used in structural alloys, pyrotechnics, flash photography, and incendiary bombs. Atomic number 12; atomic weight 24.305; melting point 649°C; boiling point 1,090°C; specific gravity 1.74 (at 20°C); valence 2. See Table at element.

- n. A light, flammable, silvery metal, and a chemical element (symbol Mg) with an atomic number of 12.

- n. A light silver-white metallic element of atomic number 12, malleable and ductile, quite permanent in dry air but tarnishing in moist air. It burns, forming (the oxide) magnesia, with the production of a blinding light (the so-called magnesium light) which is used in signaling, in pyrotechny, or in photography where a strong actinic illuminant is required. Its compounds occur abundantly, as in dolomite, talc, meerschaum, etc. Symbol Mg. Atomic weight, 24.305. Specific gravity, 1.75.
from The Century Dictionary and Cyclopedia
- n. Manganese.
- n. Chemical symbol, Mg; atomic weight, 24.4. The metallic base of the widely distributed alkaline earth magnenesia, which in various combinations, and especially in the form of the double carbonate of lime and magnesia, is one of the most abundant of the materials which make up the earth's crust.

Why magnesium is like vitamin D and how it cures depression
Dennis Mangan explains why magnesium is like vitamin D and how it cures depression:
Why magnesium is like vitamin D and how it cures depression « Isegoria
The ingredient, rich in calcium and magnesium, is derived from red seaweed Lithothamnion Coralliodides, which is harvested under licence by Marigot off the south west coast of Ireland.
The literature I have read on magnesium, and especially magnesium chloride hexahydrate, is that it can take anywhere from 3 months to a year at fairly high doses to correct a long term magnesium deficiency.
Willstätter, however, has the merit of having been the first to recognize and to prove with complete evidence the fact that magnesium is not an impurity, but is an integral part of the native, pure chlorophyll - a fact of high importance from the biological point of view.
He has shown that magnesium is held within the chlorophyll molecule in a manner which is very similar to the way in which iron is held in haemoglobin; this bond is so firm that the magnesium is not liberated even by the action of a strong alkali.
It's important to realize that long term magnesium deficiency is associated with many diseases, including cancer.
