Vitamin K

Vitamin K is a fat-soluble vitamin.
Vitamin K has 2 forms, K1, and K2,
It is advised to that take vitamin K cautiously, not too little or not too much.
K1 is found in organic foods- like in green leafy vegetables, Vitamin K1 is generally the preferred form of vitamin K because it is less toxic, works faster, is stronger and works better for certain conditions.
While K2 is found in animal products, but it’s also produced by bacteria in our gut, so it’s not essential to get it from our diet.
Certain antibiotics may interfere with vitamin K levels. This is typically only a concern if you have been on antibiotics for a long time, more than several weeks.
Vitamin K where “K” is the abbreviation of the German word “Koagulation ”
VITAMIN K is Naphthoquinone derivatives and it has a long side Isoprenoid chain.

Deficiency Symptoms
Adults are rarely found in a deficit of vitamin K but it may occur in elderly people who take medications that block vitamin K metabolism such as antibiotics, or in those with conditions that cause malabsorption of food and nutrients.
A deficiency is also possible in newborn infants because vitamin K does not cross the placenta, and breast milk contains a low amount. The limited amount of blood clotting proteins at birth increases the risk of bleeding in infants if they are not given vitamin K supplements.
The following are the most common signs of a deficiency.
  • A longer time for blood to clot or a prolonged prothrombin time (as measured in a physician’s office)
  • Bleeding
  • Hemorrhaging
  • Osteopenia or osteoporosis
