Vitamin K1 (phylloquinone)

The main vitamin K form in leafy green plants and the form used for EFSA’s vitamin K AI.

Phylloquinone is a fat-soluble vitamin K form. Food source, preparation and dietary fat can influence the intake record.

What the form means

EFSA’s AI is expressed as phylloquinone, and leafy vegetables are important sources. Menaquinones are chemically distinct vitamin K forms.

About these amounts

These values describe the named food and preparation. A 100 g comparison is not a suggested serving. Small amounts are rounded for display; an unreported amount is not zero.

Healthy European adults; phylloquinone. Adequate intake: 70 µg/day. These are population references, not individual targets.

Portions recorded by the source

  • Hummus, commercial: 2 tablespoon (33.9 g) — 5.83 µg, 8.33% of the daily reference.

Forms

  • Vitamin K1 (phylloquinone) is a form of Vitamin K.

    Vitamin K1 (phylloquinone) is a named chemical form within its parent vitamin family.

Worth knowing

  • The leafy-green form. Phylloquinone, or vitamin K1, is the main dietary vitamin K form and is abundant in leafy green vegetables. It is fat-soluble, so meal composition can affect how much is absorbed from a food.

A closer look

Food tables mostly capture K1

Food composition data primarily report phylloquinone because measurements for menaquinones are limited. A low or missing K2 value in a food table can therefore reflect the database method rather than proof that every vitamin K form is absent.
