Vitamin K1 is most commonly found in our diet, but Vitamin K2 is more effective. K2 also stays in our body significantly longer than K1. Vitamin K2 is very safe and suitable for daily use.
Vitamin K is commonly used in combination with Vitamin D and Calcium. And if your Multivitamin contains little or no Vitamin K, it is good to take a Vitamin K supplement in addition.
Vitamin K, K1 or K2?
Vitamin K is a group of fat-soluble vitamins that the body needs for the synthesis of certain proteins needed for blood clotting and the transport of calcium from the blood vessels to the bones and other tissues.
Vitamin K consists of two natural forms: Vitamin K1 and Vitamin K2. Vitamin K2 itself exists in a number of subtypes with its own molecular structure.
Vitamin K1
Vitamin K1, or phylloquinone (phylloquinone), is made by plants and is most commonly found in green leafy vegetables because it has a role in photosynthesis. Vitamin K1 can thus be considered the botanical form. It is active in the human body and has all the classic vitamin K properties. About 90% of the vitamin K intake in a typical Western diet comes from Vitamin K1.
Vitamin K2
Vitamin K2, or menaquinone (menaquinone), comes from an animal source or is made by bacteria (fermentation). The bacteria make a certain branch of the molecule longer, creating new forms of vitamin K2, such as MK-4 and MK-7. Vitamin K2 is more active and effective in the body than Vitamin K1. Vitamin K2 is a safe easily absorbable form.
MK-4
In our diet, Vitamin K2 MK-4 comes from an animal source, such as dairy. However, adequate intake of MK-4 is very challenging, even if we consume a lot of dairy from grass-fed cattle.
MK-7
Vitamin K2 MK-7 is produced by bacterial fermentation and is most commonly found in natto. Many supplements contain a Vitamin K extract from natto. On the other hand, if you prefer to eat natto to meet your daily Vitamin K2 needs, you can buy good natto from Nattodan, a Dutch natto maker.
