The next supplement for heat exhaustion, magnesium, may be a trace metal, but it bears major importance to human health.
Like calcium, magnesium is abundant in the human body (fourth-most common mineral, to be exact). It is necessary for more than 300 biochemical reactions and is responsible for strong bones, a healthy nervous system and functioning heart [source: ODS].

Along with calcium and our next two supplements, magnesium is an important electrolyte lost during dehydration.
