What is in Magnesium Complex?
Each row as the label prints it, per serving of 2 capsules. 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 Bisglycinate | 150 mg | 36% | The label names the compound (Magnesium Bisglycinate); its amount is likely the compound's weight, not the magnesium it holds, so it is not placed among other products. |
| Magnesium Malate | 150 mg | 38% | |
| Magnesium L-Threonate | 200 mg | 42% | |
| Magnesium Taurate | 150 mg | 36% | |
| Magnesium Citrate | 200 mg | 42% |
