Information-finding skills It is sometimes more useful to know where information can be found than to have memorized that information directly, particularly in areas that are developing and changing over time.

Iron supplements cause the stool to darken. Some people's stools will turn black. This is not a cause for alarm. According to the University of Maryland Medical Center, this is actually a desirable consequence of taking iron. If the stool does not turn black, your supplement may not be effectively getting absorbed.
This means that the nutrients dissolve in water in your body, which allows for you to excrete excess amounts in urine. Although iron supplements are water-soluble, the iron that they contain is not. As your body does not easily excrete excess amounts, too much iron can be toxic. Fortunately, you would need to take at least 20 milligrams of iron for every 2.2 pounds of body weight to experience iron toxicity.
