What is in Astra C?
Each row as the label prints it, per serving of 2 tablets. 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 |
|---|---|---|---|
| Proprietary BlendProprietary Blend (Combination) Note: per tablet | 660 mg | ||
| Vitamin C | 250 mg | 415% | Higher than 68% of 18,583 products listing vitamin C (median 100 mg). Per day at the most servings: 1,000 mg. |
| Zinc Citrate | 10 mg | 67% | The label names the compound (Zinc Citrate); its amount is likely the compound's weight, not the zinc it holds, so it is not placed among other products. |

Is that a lot?
Every amount on this label with a position sits within the middle 80% of the products that list the same ingredient; 5 ingredients sit inside a blend, so their amounts cannot be compared.
The NIH database records 4 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.
