All About Vitamin K

Vitamin K

What is this Vitamin?

Vitamin K is a fat soluble vitamin that was discovered in 1929.

While this nutrient may seem to have a shorter list of functions compared to other vitamins, it is the "K Vitamin" that steps in when the body sustains a cut or wound and stops the bleeding and begins the healing process.

This is because K's most famous role is to make prothrombin and other proteins which are important in blood clotting. This vitamin is often prescribed to surgery patients to prevent excessive bleeding and promote incision healing. Vitamin K shots are often given to infants 6 hours of birth to promote normal blood clotting.

There is a trio of K vitamins which are as follows:

  • K1 – This form is found in plants, especially in dark leafy vegetables, such as spinach, broccoli, Brussels sprouts, kale, and turnip greens.

  • K2 – This form is derived from intestinal bacteria.

  • K3 – This form is synthetic.

    Other Benefits

    Recent studies suggest that this crucial vitamin plays a role in bone health and counters osteoporosis. Its role on building bones is unclear, but it is thought to work synergistically with calcium, and helps the body better absorb this vital bone health mineral.

    The therapeutic uses of this vitamin include:

  • Prevention and treatment of osteoporosis.
  • Excessive menstrual bleeding.
  • Hemorrhagic disease of newborns.

    Recommended Daily Allowance

  • 65 mcg daily – Women 25 yrs and older

  • 80 mcg daily - Men 25 yrs and older


    Anyone taking blood-thinning (anticoagulant) medications such as warfarin (Coumadin) should consult a physician before taking any vitamin K supplements.

    Some experts point out that pregnant woman should not take large doses of synthetic vitamin K during the last few weeks of pregnancy because it can result in a toxic reaction in the newborn.

    It's important that everyone speak with their physician before taking any dietary supplements.

    How to Choose a Vitamin K Supplement

    First, you need to be aware that dietary supplements are not strictly regulated in the U.S. and, as such, manufacturers do not have to prove the safety, effectiveness, or even the true content of their products.

    Is this a big problem? Yes.

    In fact, according to, the leading provider of independent test results states:

    "Testing by shows that one in four supplements in the United States lacks the promised ingredients or has other serious problems."

    Therefore, we advise that you purchase your supplement from pharmaceutical GMP compliant facilities, which adhere to the most stringent manufacturing standards for supplements.

    Second, the K vitamin aids calcium, and calcium needs magnesium and vitamin D to be effective. Therefore, one should consider a comprehensive formula that contains all of these nutrients together, rather than take a stand-alone vitamin K supplement.
