The Vitamin Shoppe Iron 28 mg
Brand: The Vitamin Shoppe · Form: CAPSULE [E0159]
Our assessment
The evidence shows that iron is a crucial mineral for oxygen transport and energy production, and a 28 mg dose can be appropriate for individuals with confirmed deficiency. However, you should not take this supplement without first having your iron levels tested by a healthcare provider. Taking iron when levels are normal can lead to toxicity [NIH ODS].
How it works
Think of iron as the delivery driver for oxygen in your blood. It is a core component of hemoglobin, which carries oxygen from your lungs to every cell in your body. Without enough iron, your tissues cannot get the oxygen they need to function properly [NIH ODS].
Safety profile
FDA received 694 adverse event reports for iron supplements. Side effects include nausea, constipation, and stomach pain [FDA data]. The 28 mg dose in this product is higher than the RDA for most men (8 mg) and for postmenopausal women (8 mg), but is close to the RDA for premenopausal women (18 mg) [NIH ODS]. Data not available on specific report counts for each side effect.
Our recommendation
Only use this product if a blood test shows you have low iron stores. For most men and postmenopausal women, 28 mg daily may be too much and could cause gastrointestinal distress [NIH ODS] [FDA data]. If you are premenopausal and iron-deficient, this dose may be appropriate under medical supervision. Do not exceed the tolerable upper intake level of 45 mg per day without a doctor's guidance [NIH ODS].
