Vitamin K1 & K2, Interaction with Anticoagulant

May 11, 2019 6:00 am

During a recent group meeting, questions were raised regarding supplementing with Vitamin K1 or Vitamin K2 along with anticoagulant treatment. The table below provides a generalized summary of the Vitamin K1 and K2. The forms of Vitamin K in dietary supplements may differ depending on the supplement and the choice of the supplements may affect their absorptive behavior. This creates a challenge in regulating lab values, especially in patient who require anticoagulation therapy.

There is a lot of evidence that distinguishes between the vitamin K1 and K2 and their respective function with Cognition , Skeletal Muscle Energy Metabolism and the flexibility of the arterial wall.

In summary K1 and K2  counteract the function of the anticoagulant medications. You should consult the physician prescribing the anticoagulant before taking any vitamin K1 or K2. Even as we think of K2 having less to do with coagulation pathways, it is recommended that the patients do not take any vitamin K supplements unless cleared by their physician, since K2 may also affect the anticoagulation treatment.  As a patient who is prescribed anticoagulation treatment you should make your prescribing physician aware of ANY changes in your medications or supplements either over the counter or prescribed.

Here are several other blog posts on Vitamin K1 & K2.

Vitamin K1

April 08, 2015 7:16 pm

Vitamin K1 is a found in dark green leafy vegetables, asparagus, brussels sprouts, some grains,  olive oil, prunes, soy bean oil, and canola oil.  The body has limited storage capacity for Vitamin K and uses a recycle system to reuse it.

Vitamin K1 is a fat-soluble vitamin that after Duodenal Switch is not as easily absorbed due to the limiting contact of the food product with the bile until the common channel.  Bile is needed to absorb fatty acids and fat-soluble vitamins.

Duodenal Switch patients in need of Vitamin K1 supplements should take “Dry” or water miscible type of Vitamin K1, such as Biotech brand.  The patients laboratory studies will determine if a patient requires Vitamin K1 supplement. Duodenal Switch patients should  have laboratory studies drawn and evaluated at least on a yearly basis. Vitamin K works in a delicate balance with other supplements and should be monitored by a physician,  in at risk people.

Vitamin K1 is most know for it’s coagulation effect and the clotting cascade.  Vitamin K1 works with calcium and proteins in order to accomplish coagulation synethesis. Care should be taken with Vitamin K supplementation and anti-coagulation (blood thinners) therapy.  Please see your physician regarding any supplementation of Vitamin K and blood thinner medications.

A discovery of Vitamin K dependent proteins has led to research on Vitamin K1 in bone health.  Bone matrix proteins, specifically osteocalcin, undergo gamma carboxylation with calcium much the way coagulation factors do; this process also requires Vitamin K. Osteocalcin is a Gla-protein that is regulated by Vitamin D.  The calcium binding ability of osteocalcin requires several Vitamin K carboxylations to exert it’s effects on bone mineralization.

In adults, the causes of Vitamin K1 deficiency include the following :

Chronic illness
Malnutrition
Alcoholism
Multiple abdominal surgeries
Long-term parenteral nutrition
Malabsorption
Cholestatic disease
Parenchymal liver disease
Cystic fibrosis
Inflammatory bowel disease
Medications:  Antibiotics (cephalosporin), cholestyramines, warfarin, salicylates, anticonvulsants, Cefamandole, cefoperazone, salicylates, hydantoins, rifampin, isoniazid, barbiturates, and certain sulfa drugs, higher Vitamin E can antagonized Vitamin K)
Massive transfusion
Disseminated intravascular coagulation (DIC) – Severe
Chronic kidney disease/hemodialysis

Intake of Vitamin K1 and K2 and bone fracture risk

As always, discuss with your physicians and/or surgeon any changes in medications and supplements.  This is not meant to be an all inclusive discussion of Vitamin K.

Over the Counter Vitmain D3 better than the Prescription Vitamin D2

Vitamin D absorption is based on a complex series of pathways in the human body. We have discussed the significance of Vitamin D in a broad health condition, including Covid-19, immune system and bone structures. These articles explain the differences in detail. https://www.dssurgery.com/wp-content/uploads/2021/08/jcem5387.pdf https://www.dssurgery.com/wp-content/uploads/2021/08/jcemE447.pdf We have no finaicial insterst in the recommendations made on our site.
