Vitamin K

Vitamin K is a fat-soluble vitamin. The UK dataset reports vitamin K1, the form found in green leafy vegetables and some oils, for a small number of foods only. This page sets out what may be said about vitamin K under the authorised UK wording and which foods carry the most of it per 100 g.

Vitamin K is a fat-soluble vitamin. The UK dataset reports vitamin K1, the form found in green leafy vegetables and some oils, for a small number of foods only.

The reference intake used on UK labels (the NRV) is 0.075 mg a day. A food is a source of vitamin K when 100 g carries at least 15 % of that (0.0113 mg) and high in vitamin K at 30 % (0.0225 mg). Those are the thresholds every food page here uses.

What Vitamin K does in the body.

Vitamin K contributes to normal blood clotting and to the maintenance of normal bones.

That is the authorised wording, and it is credited to the nutrient itself. Nothing on this page goes beyond it.

How much counts as a source.

The Nutrient Reference Value for vitamin K on UK labels is 0.075 mg a day. A food counts as a source of vitamin K at 15 % of that per 100 g (0.0112 mg) and as high in vitamin K at 30 % (0.0225 mg); drinks use half those percentages per 100 ml. Those are the thresholds every food page here applies, and the only basis on which a food page says “source of” or “high in”.
