Is it normal to get an upset stomach, become constipated, or both after taking iron supplements?
Many people who take iron supplements experience side effects that make it difficult to follow the recommended dosing. It has been estimated that up to 25% of patients who take iron supplements will experience side effects in their digestive tract – most commonly an upset stomach, constipation, or both. Iron supplements are absorbed better if taken one hour before meals. However your doctor may tell you to take your iron with food to reduce an upset stomach. Also, starting with half the recommended dose and gradually increasing to the full dose may help minimize these side effects. If iron makes you constipated, consider taking a stool softener such as docusate sodium along with your iron.
