What is Vitamin K

Vitamin K is a fat soluble vitamin (soluble in fat but not soluble in water) which is heat stable. It is involved in coagulation, bone mineralization , and cell growth. It has anti-inflammatory properties and plays a role in cardiovascular health.
There are two types of vitamin K:
– Vitamin K1 or phylloquinone: it is found mainly in green vegetables.
– Vitamin K2 or menaquinone: it is synthesized in our organism by the intestinal flora, but in insufficient quantity to satisfy the needs of the organism. It is found mainly in dairy products, fermented products and offal.

We recommend a vitamin K intake of 1 μg / kg body weight / d (for adults).

True vitamin K deficiencies are rare in adults. On the other hand, they are frequent in newborns and premature infants. Moderate deficits are rather widespread.
