How to Use

Take 1 tablet daily with a meal and plenty of water (or as directed by your clinician). If sensitive, some clinicians suggest trying every-other-day dosing.

Cautions & Considerations

Critical safety warning

Interactions & timing

Separate iron by several hours from tetracycline/quinolone antibiotics, thyroid meds, and calcium supplements. Check with your provider if pregnant, on multiple medications, or managing chronic conditions.
