How do the amounts compare with the Daily Value and the upper limit?
The FDA Daily Value for vitamin K is 120 mcg (adults and children 4 and older). The median product gives 67% of it per serving; the 90th percentile 150%.
The upper limit is for total intake from food, water and supplements unless stated, and does not apply under medical supervision. A label amount is what the maker printed. This is data, not advice: the NIH ODS fact sheets explain what each nutrient does.
Sources: 21 CFR 101.9(c)(8)(iv) (Daily Values); Institute of Medicine, DRI summary tables (2011) (upper limits); on reading them, the FDA's Daily Value page.
Which forms of vitamin K do labels name?
Vitamin K1 (phylloquinone) is the form named most often: 1,879 of the 4,722 vitamin K products (40%), ahead of vitamin K2 as MK-7 (1,376, 29%) and vitamin K2 as MK-4 (277, 6%). A product naming two forms counts in both; the table below gives every form.
