                              essential element which influences many enzymes 
                              needed to produce cellular energy and nerve and 
                              muscle message transmission. It affects nervous, 
                              muscular and cardiovascular systems. Magnesium is 
                              found mainly in bone, also in muscle and other tissues: 
                              deficiency can lead to neuromuscular and central 
                              nervous system irritability, muscle twitches and 
                              weakness. Magnesium excess has been found to result 
                              in mental depression and cardiac arrest. |  |
