Iron supplements can cause several side effects, particularly when taken on an empty stomach. Clinical studies have documented these common effects:
- Gastrointestinal issues: Constipation, nausea, stomach pain
- Stool changes: Black or dark stools
- Tooth staining: Temporary darkening of teeth
To minimize side effects, start with a lower dose and gradually increase it. Taking a slow-release formula or breaking doses throughout the day can also help. If side effects persist, consult your healthcare provider about alternative forms of iron supplementation.
