What is in Nad+?
Each row as the label prints it, per serving of 3 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 |
|---|---|---|---|
| Nicotinamide Riboside Chloride | 1,500 mg | 9,375%* | This amount is far outside what other labels list for niacin, or disagrees with the label's own %DV: possibly a unit or transcription slip in the database. Check the label image on DSLD. |
| Resveratrolas Polygonum cuspidatum root extract20:1, equivalent to 6,000 mg of raw polygonum cuspidatum root | 300 mg | Higher than 92% of 1,123 products listing resveratrol (median 50 mg). | |
| Quercetinas Sophora japonica Flower Extract30:1, equivalent to 6,000 mg of raw Sophora japonica flower | 200 mg | Higher than 66% of 1,548 products listing quercetin (median 100 mg). | |
| Bioperineas Black Pepper Fruit Extract95% piperine | 10 mg | Higher than 71% of 2,363 products listing black pepper (median 5 mg). |
* % Daily Value computed from the printed amount and the FDA Daily Value (21 CFR 101.9); the label prints none for that row.

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:
- Its 300 mg of resveratrol is higher than 92% of the 1,123 resveratrol products that print an amount; 85 list more.
The NIH database records one serving 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.
