What is in Magnesium/Potassium Complex?
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 |
|---|---|---|---|
| Magnesium Complexas Magnesium Aspartate, Magnesium OxideMagnesium Complex (Form: as Magnesium Aspartate, Magnesium Oxide) | 90 mg | 23% | The label names the compound (Magnesium Complex); its amount is likely the compound's weight, not the magnesium it holds, so it is not placed among other products. |
| Potassium Complexas Potassium Aspartate, Potassium ChloridePotassium Complex (Form: as Potassium Aspartate, Potassium Chloride) | 90 mg | 3% | The label names the compound (Potassium Complex); its amount is likely the compound's weight, not the potassium it holds, so it is not placed among other products. |
