Objective: To explore the relationship between vitamin K levels and pregnancy-related diseases and adverse pregnancy outcomes in early pregnancy.

Methods: A convenience sampling method was used to select 367 women in early pregnancy who were enrolled in the Shunyi Women's and Children's Hospital of Beijing Children's Hospital from October 2018 to September 2019. Basic information such as age, height, and pre-pregnancy weight of the respondents was collected, blood samples were taken and the concentration of vitamin K(vitamin K1, MK-4 and MK-7) was measured by liquid chromatography tandem mass spectrometry(LC-MS/MS). Follow-up visits were conducted to collect information on whether the respondents had pregnancy-related disease and their pregnancy outcomes. The relationship between vitamin K concentration and pregnancy-related diseases and adverse pregnancy outcomes was analyzed by partial correlation test and binary logistic regression.

Results: The mean age of the respondents was 29.3 years, with a range of pre-pregnancy body mass index from 15.43 to 40.40 and weeks of pregnancy range from 5.9 to 14.0 weeks. The concentrations of MK-7, vitamin K1, and MK-4 in pregnant women(M(P25, P75))were 1.093(0.295, 3.325)ng/mL, 0.526(0.359, 0.681)ng/mL and 0.021(0.018, 0.026)ng/mL, respectively. There was a significant negative correlation between serum MK-7 levels in early pregnancy and the development of gestational diabetes mellitus(GDM)(P=0.032).
The result of binary logistic regression analysis showed that MK-7 deficiency was a risk factor for GDM(OR=4.276, P=0.034) after adjusting for confounding factors: age, ethnicity, BMI, parity, vitamin D level, physical activity, low-density lipoprotein(LDL), high-density lipoprotein(HDL), and gestational age.

Conclusion: Serum MK-7 levels in early pregnancy are negatively associated with the development of GDM in women. It is therefore essential to pay more attention to the nutritional status of vitamin K in pregnant women in early pregnancy.

VitaminDWiki – Overview Vitamin K and Vitamin D contains

Vitamin K2 is similar to D3 in many ways

  1. Both vitamins were initially confused with its lesser form (D2 ==> D3, K1 ==> K2)
  2. Both vitamins appear to influence health in large number of ways
  3. Both vitamins in the body are about 1/10 that of a century ago
    Example: Grass-fed beef has a lot more K2, D3, and Magnesium
  4. Need very little of both vitamins: <1 milligram daily
  5. When Vitamin D3 is increased, it appears that Vitamin K2 should also be increased
  6. Vitamin K2 understanding and research is about 20 years behind that of Vitamin D3
    One of the reasons: No simple blood test for K2 as of Dec 2024
