Nitrogen gas is not flammable. It will not readily burn or support combustion. It is an inert material, and this inert quality makes it useful in industrial applications to prevent combustion of other materials.
It is chelated, or attached, to aspartic acid, an amino acid present in protein rich foods. This helps the body absorb the magnesium. Magnesium aspartate is used in disease prevention, treatment and as a mineral supplement.
Magnesium also helps protect blood vessels, which is where most of what we call heart disease actually happens. Magnesium is also a natural blood thinner, much like aspirin, so many doctors and researchers believe that it may help prevent heart attacks and strokes.
