We Consume Lots Of Phylloquinone, But Can't Absorb It
Phylloquinone is the major dietary form of the K vitamins, and it has a much faster turnover than the other fat-soluble vitamins A, D, and E. (source 🗗)
But vitamin K1 found in plants is poorly absorbed by the body.
It seems to be less than 10% of the K1 found in plants is actually absorbed. (source 🗗)
Also, the majority of the daily dietary intake of phylloquinone gets lost by excretion, around 60-70%.
It emphasizes the need for a steady dietary supply. (source 🗗)
