Why Does Your Body Need Vitamin K?
Did you know that sudden weight loss can affect vitamin absorption in your blood?
Vitamin K is a fat-soluble vitamin that is essential for many bodily functions.
It requires body fat to be adequately absorbed in the blood.
So before you jump into another fad diet, read on to find out just how essential Vitamin K is for the body.
Vitamin K: An Overview
Vitamin K is a fat-soluble vitamin that naturally occurs in two forms.
Phyloquinone, or Vitamin K1, is the primary type found in green leafy vegetables like kale and spinach.
Menaquinone (MK), also called Vitamin K2, is located in fermented foods.
Vitamin K2 can have various subtypes.
MK-5 and MK-15 are in fermented foods, while MK-4 is in chicken, butter, and egg yolks.
Vitamin K is necessary for healthy bone-building in the body.
In addition, Prothrombin, an essential protein for blood clotting, is dependent on Vitamin K.??
Why Does The Human Body Need Vitamin K?
Wound Healing?
Blood clotting is a naturally occurring process that helps prevent excessive blood loss in an injury.
It involves a cascade of coordinated reactions that plugs the injury site with a clot.
Prothrombin, a protein essential for blood clotting, needs Vitamin K for proper functioning.?
Thus Vitamin K is necessary to heal wounds.
Preventing Osteoporosis
An enzyme called gamma-glutamyl carboxylase is necessary for adequately functioning osteocalcin, a protein in bone.
This enzyme depends on Vitamin K.
Thus, you lose bone mass and density when your body is low on Vitamin K.
It can cause bone thinning, called osteoporosis, and frequent fractures.
Blood Pressure Maintenance
Some studies show that adequate Vitamin K can prevent hypertension.
Vitamin K interacts with and regulates your blood calcium levels.
As a result, it keeps your blood pressure in check.
Prevention Of Heart Disease
Calcium can get mineralized and deposited on the walls of our blood vessels as we age.
Adequate amounts of Vitamin K can help remineralize the calcium and prevent heart ailments.
Improving Memory In Older Adults
Sphingolipids are found in brain cell membranes.
These lipids are involved in cellular metabolism.
Changes in their functioning can cause neurodegenerative disorders like Alzheimer’s disease.
Higher levels of phylloquinone can improve memory and prevent age-related cognitive decline.
Vitamin K Deficiency
The average amount of Vitamin K is 120 micrograms for adult men and 90 micrograms for adult women.?
Vitamin K deficiency is rare in adults but not impossible.
Some medications can cause a decreased absorption of Vitamin K in the blood.
Infants are prone to Vitamin K deficiency as mother’s milk has a low concentration, and this vitamin cannot cross the placenta.
