Vitamin K Substances

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Vitamin K is an essential cofactor in the hepatic synthesis of prothrombin and other blood clotting factors and in the function of proteins, such as osteocalcin, important for bone development.

The daily needs during pregnancy and breastfeeding are 90 micrograms a day. Vitamin K is found in many foods in the form of phytomenadione and is also synthesized by intestinal bacteria in the form of menaquinone. (Booth 2012).

With a varied diet, vitamin K supplements are not required. (Ares 2015)

Human milk is low in vitamin K and at birth there are not enough intestinal bacteria to synthesize it. Newborns require a vitamin K supplement to prevent hemorrhagic disease of the newborn (Greer 2001): an intramuscular dose of 0.5 to 1 mg (500 to 1,000 micrograms) at birth or orally 2 mg at birth followed by weekly doses for the first 12 weeks. (Ng 2018, Ares 2015)

Vitamin K occurs naturally in human milk and colostrum in concentrations of 1 to 20 micrograms/L and increases with maternal administration of vitamin K to levels between 50 and 150 micrograms/L (Bolisetty 1998, Greer 1997), but this is still insufficient to prevent hemorrhagic disease of the newborn, which requires the administration of vitamin K, regardless of the dose of Vitamin K that the mother takes. (Sauberan 2019)

American Academy of Pediatrics: medication usually compatible with breastfeeding. (AAP 2001)

WHO List of Essential Medicines: compatible with breastfeeding. (WHO 2002)

Alternatives

We do not have alternatives for Vitamin K Substances since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
