Phylloquinone - primary dietary form of vitamin K supporting blood clotting
We rank Vitamin K1 by price per 75mcg - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Vitamin K1, also known as phylloquinone, is a fat soluble vitamin. This means it requires fat to be absorbed by the body. It is the primary form of vitamin K found in the food we eat.
It is used mainly to support blood clotting. This is the process where the body creates a plug to stop bleeding after an injury.
To create the supplement, the vitamin is extracted from plant sources. This concentrated extract is then mixed with a carrier oil or a filler to ensure it is stable before being sealed into capsules or pressed into tablets.
This ingredient is generally mid range in price. This is because the raw plant materials are relatively easy to source, but the process of extracting and stabilising the vitamin requires specific industrial equipment.
