Vitamin K in celery: stalk size changes the answer

Start with an edible-food amount

The USDA SR Legacy 2018 raw-celery entry gives 29.3 mcg vitamin K1 per 100 g. A count of stalks is less precise because stalk size varies. The number describes the named historical reference food; it does not establish the concentration in every bunch or in celery juice. [1]

Celery is not vitamin-K-free

A small amount of celery can make a smaller contribution than a large salad, but it still contains K1. For someone taking warfarin, consistency of total vitamin K intake is relevant. A low-looking value is not a reason to change medication, and the presence of vitamin K alone is not a reason to ban celery. [2]

Compare two stated portions

Imagine one recipe uses 40 g raw celery and another uses 120 g. Their estimated K1 contributions are 11.72 and 35.16 mcg, respectively. Those are ingredient contributions, not complete-meal totals. Juicing a large quantity cannot be equated to eating one unspecified stalk using this table. [1]

Hypothetical example — work through the stated example; not a product endorsement or treatment plan
Raw edible celery	Calculation	K1 estimate
40 g	29.3 × 0.4	11.72 mcg
120 g	29.3 × 1.2	35.16 mcg
