Vitamin K in okra: use the portion and preparation

The reference amount

USDA’s final SR Legacy 2018 entry for raw okra reports 31.3 mcg of vitamin K1 per 100 g. This is a historical composition estimate, not a measurement of a current crop. Okra contributes vitamin K, but calling it high without specifying a serving obscures how much someone actually eats. [1]

What that amount means

Vitamin K supports the activation of proteins involved in normal clotting and bone metabolism. Finding K1 in a vegetable does not establish that eating more treats a clotting disorder or osteoporosis. People taking warfarin need consistency in vitamin K intake; the decision is not simply that all vegetables containing it must be avoided. Discuss major changes with the treating team. [2]

Raw weight is not a recipe calculation

A hypothetical 80 g raw portion supplies about 25 mcg K1; 160 g supplies about 50 mcg. A gumbo or fried-okra dish includes other ingredients, and cooking changes the relationship between food weight and the original raw entry. Use a matching cooked-food or recipe calculation when estimating that dish. [1]

Hypothetical example — work through the stated example; not a product endorsement or treatment plan
Raw edible okra	Calculation	K1 estimate
80 g	31.3 × 0.8	25.04 mcg
160 g	31.3 × 1.6	50.08 mcg
