What is in Kidney Defender?
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 |
|---|---|---|---|
| Niacin | 100 mg | 625% | Higher than 88% of 12,413 products listing niacin (median 20 mg). Per day at the most servings: 200 mg. 5.7 times the adult UL a day. |
| Proprietary Blend | 1,292 mg | ||
| Sodium Bicarbonate | in the blend, no amount given | ||
| Calcium Carbonate | in the blend, no amount given | The label names the compound (Calcium Carbonate); its amount is likely the compound's weight, not the calcium it holds, so it is not placed among other products. | |
| Isoquercetinas Sophora japonica Extract95% | in the blend, no amount given |

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:
- At 2 servings a day, the most its directions give, the label lists 200 mg of niacin, 5.7 times the adult Tolerable Upper Intake Level.
The NIH database records 2 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.
The Tolerable Upper Intake Level is the most of a nutrient per day, from food, water and supplements together, that is likely to pose no risk for almost all adults (Institute of Medicine, 2011). It does not apply under medical supervision. This page compares labels; it is not medical advice.
