What is in Natto-K?
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 |
|---|---|---|---|
| Calciumas Calcium CitrateCalcium (Form: from Coral Calcium) | 14 mg | 1% | 95% of 17,831 products listing calcium give more (median 115 mg). Per day at the most servings: 42 mg. |
| Magnesiumas Magnesium CitrateMagnesium (Form: from Coral Calcium) | 0.04 mg | 1% | This amount is far outside what other labels list for magnesium, or disagrees with the label's own %DV: possibly a unit or transcription slip in the database. Check the label image on DSLD. |

Is that a lot?
The rows in the top or bottom tenth of the products that list the same ingredient, and any above the adult upper limit at the most servings a day the directions give:
- 95% of the 17,831 products that print an amount of calcium list more than its 14 mg of calcium (median 115 mg).
The NIH database records 3 servings a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.
