What is in Winter Wellness?
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 |
|---|---|---|---|
| L-Cysteine | 700 mg | Higher than 97% of 516 products listing cysteine (median 85 mg). | |
| L-Theanine | 280 mg | Higher than 92% of 1,602 products listing theanine (median 100 mg). |

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 700 mg of L-cysteine (filed by NIH under cysteine) is higher than 97% of the 516 cysteine products that print an amount; 12 list more.
- Its 280 mg of L-theanine (filed by NIH under theanine) is higher than 92% of the 1,602 theanine products that print an amount; 126 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.
