Vitamin K2

Improves bone health and is important in the regulation of blood clotting.

Vitamin K2 NRV:

The NRV recommends around 75µg a day. Her.9 contains 70mcg (amounting to roughly half a cup of Brussel sprouts) an impressive 94% of your NRV for the day.


Major Functions:

  • Plays an important role in the formation of proteins essential for the maintenance of healthy bones and teeth 
  • Essential for the formation of several proteins that regulate blood clotting supporting the healing of open wounds



Unlike most prenatal multivitamins that use vitamin K1, Her.9 uses vitamin K2 which is more easily absorbed than K1 due to the vitamin typically being sourced from foods that contain fat. Her9 uses the purest and most biologically active form of vitamin K2, K2VITAL®, which can be properly absorbed and utilised in the body. K2VITAL® is particularly more efficacious at targeting the Osteoblasts (bone producing proteins) that integrate calcium into bones and teeth and circulates in the blood longer than K1 due to its long side chain allowing it to be more effectively utilised in the tissues located throughout the body.

During pregnancy K2VITAL® helps to support bone health of women undergoing substantial skeletal changes in preparation for birth as well as the skeletal development of new-born babies. 

Vitamin K is also important in the prevention of a rare bleeding disorder called Vitamin K Deficiency Bleeding (VKDB) and is required for protein formation in the liver which is particularly important during labour and just after a mother has given birth, when the body is recovering and starting to heal.
