Cramping and muscle soreness are directly related to lack of magnesium in the body.
Magnesium is used in the communication between nerves and muscle contraction. A lack of magnesium has been thought to be the cause of cramping.
Magnesium is hard to obtain through diet even if you eat lots of leafy green vegetables because of the quality of soil our food is grown in.
In addition to a general lack of magnesium in today's diet, fighters, athletes and everyone who exerts muscular energy needs magnesium even more than the average person.
The form of magnesium that is best absorbed is transdermal magnesium since it goes directly onto your skin, then immediatly gets sucked into your blood stream rather than going through your digestive system and having to try to survive through your stomach acid, get released from the capsule shell and until it's finally absorbed.
