What is in Liquid D and K Natural Vanilla Flavor?
Each row as the label prints it, per serving of 1 ml. 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 |
|---|---|---|---|
| Vitamin D3as Cholecalciferol1,000 IU | 25 mcg (1,000 IU) | 125% | Higher than 59% of 14,175 products listing vitamin D (median 15 mcg). |
| Vitamin K1 | 500 mcg | 417% | This amount is far outside what other labels list for vitamin K, or disagrees with the label's own %DV: possibly a unit or transcription slip in the database. Check the label image on DSLD. |
| Vitamin K2as Menaquinone-4, Menaquinone-7 | 1,045 mg |
