Vitamin K supplementation during pregnancy

Vitamin K supplements during pregnancy.
Vitamin K requirements through pregnancy.

Vitamin K is a vital fact for our overall good health, let alone pregnancy. As we discussed in a previous post, the daily minimum requirements for vitamin K are 120mcg for men and 90mcg for women. According to the National Institue of Health (NIH), pregnant women don’t need any additional dosage of vitamin K. They also need about 90mcg daily.

It is a common belief that women in pregnancy or lactation require a higher nutrient supply of many vitamins. The role of Vitamin K during pregnancy is largely unknown though. Vitamin K deficiency can be seen when certain drugs are consumed during pregnancy. These drugs can impede women’s metabolism of vitamin K (1). Administration and dosages of vitamin K can vary. When vitamin K absorption is impaired, taking vitamin K supplements is required. The best solution, when vitamin K supplementation is required is through a multivitamin. This way is considered to be more beneficial than taking vitamin K alone.

Vitamin K supplement is not necessary in normal pregnancy. Only in some impaired conditions, deficiency can be observed. Always discuss your concerns with your physician. Our western diet is so different than the diet of our ancestors, that we may don’t consume enough, or we may not absorb the proper doses of micronutrients in food. Vitamin K is no exception. The human body can’t deposit high levels of vitamin K, although it’s fat-soluble.  

How obtain the RDI vitamin K through pregnancy.

If you do not have any particular condition, or you’re physician hasn’t advised you differently, you won’t need any extra vitamin K supplement through pregnancy or lactation. The recommended daily intake of vitamin K shouldn’t be difficult to be reached in a whole food plant-based diet.

The main source of vitamin K is leafy green vegetables. Such common vegetables are cabbage, spinach, kale, and broccoli. Try to eat a combination of these vegetables every day. Other common plant sources of vitamin K are carrot juice, pumpkins, pomegranates, blueberries, and grapes. As you see, vitamin K could be rather unusual in a healthy vegan diet.

Always consult your physician. Especially in pregnancy.
