Why Do Iron Supplements Upset My Stomach?

Many medications or supplements come with certain expected side effects that must be managed in simple ways, and the world of iron supplements is no exception. An upset stomach is one of the most common side effects of some iron supplements, but there are also some simple ways to prevent and counteract these effects for many people.

At Pharmics Inc., we're proud to offer the very best selection of iron supplements on the market, including non-constipating iron supplements that are easy on the stomach and easy to digest. Here's a primer on why some people deal with constipation or other stomach issues as a side effect of iron supplementation, plus what can be done to avoid this concern.

Why Some Iron Supplements Cause Upset Stomach

The primary reason why some people deal with an upset stomach after taking iron supplements traces back to absorption in the body. In some cases, iron supplements go through an oxidization process in the gut that causes issues with digestion.

This can happen particularly if you take iron supplements on an empty stomach or alongside certain foods, such as dairy products or caffeine. Iron supplements that contain ferrous sulfate are also more likely to cause constipation and other digestive problems, since this form of iron is harder for the body to absorb.

Iron Supplementation Tips to Avoid Upset Stomach

In many cases, iron supplements will come with specific directions on how to take them to avoid upset stomach issues. These may include:

• Fruit juice: Drinking orange or other acidic fruit juices alongside iron supplements can help increase absorption and reduce stomach discomfort.
• Iron-rich foods: Taking iron supplements with a meal that contains iron-rich foods, such as lean meats, fish, or leafy greens, can also improve absorption and lessen digestive issues.
• Probiotics: Adding probiotics to your daily routine can help promote healthy gut bacteria and improve digestion, potentially reducing the likelihood of stomach issues.
• No empty stomach: Unless otherwise directed by a doctor, it's best to take iron supplements with food to avoid upsetting the stomach.

The Right Iron Supplements

In addition to the tips mentioned above, choosing the right iron supplement can also make a big difference in preventing stomach upset. As we mentioned earlier, non-constipating iron supplements like active iron or iron protein succinylate tend to be easier on the stomach and less likely to cause digestive issues. These forms of iron are also more readily absorbed by the body, making them a great choice for those who struggle with iron deficiency anemia but don't want to deal with uncomfortable side effects.
