Magnesium: This is an essential mineral for metabolic function. Magnesium in food
sources is declining. Mg helps in glucose and insulin metabolism, PMS symptoms,
bowel regularity, headaches, and leg cramps (especially in pregnant women). The best
sources of Mg in foods are green leafy vegetables (like spinach), fish, nuts, legumes,
oatmeal, potato skins, and whole grains. To be safe, do not take more than 350mg of
supplemental Magnesium (can lead to nausea, diarrhea, muscle weakness, low BP,
coma).
