What is in Iron Rx?
Each row as the label prints it, per serving of 1 capsule. The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).
| Ingredient | Amount | % DV | Among products listing it |
|---|---|---|---|
| Vitamin Cas Ascorbic Acid | 100 mg | 167% | 50% of 18,583 products listing vitamin C give more (median 100 mg). |
| Ironas Iron Amino Acid ChelateIron (Form: from Iron Amino Acid Chelate) | 29 mg | 29% | This amount is far outside what other labels list for iron, or disagrees with the label's own %DV: possibly a unit or transcription slip in the database. Check the label image on DSLD. |
