Iron's Dangers

Too much iron can block our absorption of copper and too little copper makes us store too much iron With aging our tissues lose copper as they store excess iron Because of those changes we need more vitamin E as we age SUMMARY Iron is a potentially toxic heavy metal an excess can cause cancer heart disease and other illnesses
