TOO MUCH IRON, TOO MUCH OF GOOD THING
People taking iron-fortified vitamins without a diagnosed iron
deficiency could get too much of a good thing, a Florida State
University study finds. High levels of iron caused Parkinson's-like
symptoms even in healthy mice without apparent risk factors for the
illness, while accelerating the decline and death of those already
diagnosed with the disease, according to the study published in
"Experimental Neurology." In contrast, low levels of iron delayed
onset of Parkinson's in mice with risk factors and slowed progress of
the disease in those already infected. While low levels of iron delay
the onset of the disease once the neurological stage is set or slows
the degenerative progress, iron toxicity both precipitates
Parkinson's symptoms and hastens decline and death in existing victims.
