What is in Mag Theanine?
Each row as the label prints it, per serving of 1 film coated tablet. 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 |
|---|---|---|---|
| Theanine | 200 mg | Higher than 61% of 1,602 products listing theanine (median 100 mg). Per day at the most servings: 400 mg. | |
| Magnesium Glycinate | 1,077 mg | 256%* | The label names the compound (Magnesium Glycinate); its amount is likely the compound's weight, not the magnesium it holds, so it is not placed among other products. |
| Magnesium | 150 mg | ||
| Glycine | 922 mg | ||
| Glycine | 77.6 mg | 76% of 1,078 products listing glycine give more (median 300 mg). Per day at the most servings: 155.2 mg. | |
| Total Glycine | 1,000 mg |
* % Daily Value computed from the printed amount and the FDA Daily Value (21 CFR 101.9); the label prints none for that row.
