Iron supplements can cause several side effects, as documented in clinical research. Common side effects include:
- Constipation or diarrhea
- Dark or black stools
- Stomach pain or nausea
- Temporary tooth staining
To minimize these effects, start with a lower dose and gradually increase it. Taking supplements with food can help reduce stomach issues, though this may decrease absorption. If side effects persist, consider switching to a different form of iron (like iron bisglycinate) which may be better tolerated. Always consult your healthcare provider about persistent side effects.
