Preventing Preeclampsia Part I: Connecting the K2 Dots

We don’t know the exact cause of preeclampsia or eclampsia, and current treatments are only moderately effective. Many women who develop it will deliver preterm. Since is a severe progression of preeclampsia which involves seizures, we will only be using the term “preeclampsia.” Converging evidence suggests that supplementation with certain vitamins, micronutrients, minerals, antioxidants, and amino acids could prevent or possibly treat preeclampsia and eclampsia. We will be discussing the evidence that supports each, and make a case for the theory that nutritional deficiencies are the cause, therefore nutritional therapy is the treatment. This post is about Vitamin K2, and future posts will cover the other nutritional therapies.

Vitamin K2

Vitamin K2 (also known as MK-7 and menaquinone) is a little understood and little known vitamin and cofactor. It plays a major role the proper absorption of calcium, the prevention of atherosclerosis, suppressing inflammation caused by oxidative stress, reducing the risk of type 2 diabetes, increasing insulin sensitivity, and many other processes which we are still uncovering. Right now there isn’t even a test that is used as the “gold standard” method for assessing total Vitamin K status. What we do know, is that most people are not getting enough of it from the foods here in America. 
Let us take a look at some of the risk factors and lab values associated with preeclampsia and eclampsia (according to WebMD, 2018) and connect them to K2 deficiency.

Risk Factor #1: Preexisting Protein C or Protein S deficiency

Protein C and Protein S are both Vitamin K dependent proteins. This means that the body requires Vitamin K to be able to activate Protein C and Protein S. Protein C is made primarily in the liver, but 50% of protein S is made in the endothelial cells of the vascular walls (Frannsen et al., 2017). Vitamin K1 activates coagulation factors in the liver, but vitamin K2 activates the vitamin K dependent proteins that exist extrahepatically (outside the liver) (Frannsen et al., 2017). If a vitamin K deficiency exists, than Protein C or Protein S deficiency will also exist. If protein C or protein S deficiency is a risk factor for eclampsia, it is certainly possible then that the root cause is actually vitamin K2 deficiency. 

I was diagnosed with “mild” protien S deficiency after having three miscarriages.  I did not know then what I know now.  I had to take aspirin to be able to maintain the pregnancy.  If I had known better, I would have replenished my K2 before trying again.  I was never tested for K2 deficiency and did not even know it could be a possible cause at the time.  I will be writing about recurrent miscarriage in the near future and will certainly discuss this further.

Why does this matter in preeclampsia?

It is important to realize that calcium plays a direct role in vasodilation (the dilation of blood vessels, which decreases blood pressure), though we won’t get into the specific mechanisms here.
