Do Iron Supplements Result in Dark Stool? Causes, Safety & Best Tips for Supplements

For many individuals who are starting on iron supplementation, this might be the first time they experience a peculiar and rather troublesome side effect – dark stool. Changing bowl habits leads to needless worry and many questions, thus, do iron supplements cause dark stool and if yes, is it a cause of concern? In reality, having dark stool after consuming iron is tremendously common among supplement consumers and the likelihood that it poses any harm is small when it comes to such patients. Knowing the reason behind this effect, one will be able to make his or her life easier and stress-free when using iron supplements especially if using high-quality daily iron nutritional products like youlevhong iron supplements.

To go straight to the point, yes, iron supplementation can result in dark stool and this is a normal response in most cases. The underlying mechanism of this effect is rather simple. When consuming iron supplements in a form of pills, not all iron is absorbed and used by the intestines. What is not absorbed remains in the intestines and reacts with hydrogen sulfide formed by intestinal microorganisms and digestive juices. The result of this chemical reaction is iron sulfide that gets attached to the stool giving it the black color. This is the main reason why iron supplementation leads to stool discoloration.
It is important to tell apart the harmless dark stool caused by iron supplements from the dangerous dark stool that is a sign of any internal bleeding. The stool that is the result of iron supplementation is characterized by its dark color, hardness and absence of any unpleasant fishy odor. Additionally, dark color of stool will get back to normal within a couple of days. On the other hand, dark stool through bleeding will be of a different nature being sticky, shiny, tar-like with a very unpleasant smell and accompanied by other symptoms as abdominal pain, dizziness, weakness and nausea.
