Difference Between Vitamin K and K2
What is Vitamin K? Vitamin K is not a single vitamin, but rather a group of fat-soluble, chemically related vitamins, called with the common name “vitamin K”. Оur bodies store it in the fatty tissue and the liver.
There are 3 forms of vitamin K, known in the biochemistry as naphthoquinones:
Vitamin K1, phylloquinone, found naturally in certain plant foods; Vitamin K2, menaquinone, synthesized from certain bacteria in the digestive tract and delivered by the consumption of certain foods; Vitamin K3, menadione, a synthetic form that is not recommended for intake because of a danger of toxicity.
