While iron supplements are generally safe, they can cause several side effects. Studies show the most common side effects include:
- Gastrointestinal issues: Constipation, nausea, stomach pain
- Stool changes: Dark or black stools
- Temporary tooth staining: Can be prevented by using a straw
To minimize side effects, start with a lower dose and gradually increase it. Taking a slow-release form of iron or splitting the dose throughout the day can also help reduce adverse reactions. If side effects persist, consult your healthcare provider about alternative formulations.
