Why do people need Magnesium?

Answer 1

It is a very complicated issue but in short, it provides energy for your cells, helps the muscles to contract and helps break down protein for the body to use. Think about this, your heart is a muscle so if you don't have enough magnesium your heart wouldn't beat the way it should then your body wouldn't get the blood it needs or enough oxygen. and for its relatively distinct oxidation for being alkaline, it is favorable for replacement reactions in intermediate steps. You have to make sure however, not to get too much either.
