Iron deficiency is most common among women (approximately 12% of US women). This supplement has a controlled delivery system that provides high potency iron while being gentle on your stomach, so you experience fewer GI side effects (nausea and abdominal discomfort) common to iron use. Easy to swallow. Do not use: if you are taking other supplements containing iron; for more than six months unless directed by your doctor. Consult a doctor before use if you are pregnant or nursing. Oral iron supplements: may interfere with absorption of certain oral antibiotics (e.g. tetracycline) and other medications. These products should not be taken within two (2) h.
