A: FROM MENTOR KRISTIN TAGHON

Hi, Kerala
I did a search on www.google.com
with the phrase "too much of one mineral" and
found the url,
http://1stholistic.com/Nutrition/hol_nutr-toomuch-supplement.htm
It talks about how taking too much one one mineral can be
toxic to your body.
And then your body can start malfunctioning.
