Vitamin K And Newborns: What You Need To Know

Vitamin K is an essential nutrient that plays a crucial role in blood clotting. Newborns, however, have low levels of vitamin K and are at risk of developing a rare bleeding disorder known as vitamin K deficiency bleeding (VKDB). Here's what you need to know about vitamin K and newborns:

Why do newborns need vitamin K?

Newborns have low levels of vitamin K because the nutrient does not pass easily through the placenta, and breast milk is also low in vitamin K. Vitamin K is crucial for blood clotting, and a deficiency can result in VKDB, which can cause internal bleeding in the brain, intestines, or other organs.

How common is VKDB?

VKDB is a rare but serious condition that affects approximately 1 in 60-250 newborns who have not received vitamin K supplementation. Early-onset VKDB occurs within the first 24 hours of life, while late-onset VKDB occurs between 1-12 weeks of age.

How is vitamin K given to newborns?

Vitamin K can be given to newborns in three ways: orally, intramuscularly (injection into the muscle), or subcutaneously (injection under the skin). The American Academy of Pediatrics recommends that all newborns receive vitamin K via an injection in the muscle soon after birth to prevent VKDB.

Are there any risks associated with vitamin K supplementation?

There have been concerns about the potential link between vitamin K injections and childhood cancer, but numerous studies have found no evidence of such a link. The benefits of vitamin K supplementation in preventing VKDB far outweigh any risks.

What else can parents do to ensure their baby's health?

In addition to vitamin K supplementation, parents can help keep their baby healthy by following a regular check-up schedule with a pediatrician, ensuring their baby is getting proper nutrition, and providing a safe and nurturing environment for their baby to grow and develop.


Newborns typically receive a single dose of vitamin K soon after birth to help prevent bleeding disorders. The recommended dosage of vitamin K for newborns is 0.5 to 1 milligram, which is typically given as an injection. This dose is based on the infant's weight and is usually administered within the first few hours after birth. It is important to follow the recommendations of your healthcare provider regarding vitamin K supplementation for your newborn.

Side Effects and Warnings

Vitamin K is generally safe for newborns when administered in the recommended dosage. However, as with any medication or supplement, there are potential side effects and risks that parents and healthcare providers should be aware of.

Some of the potential side effects of vitamin K injection in newborns include:

  • Localized swelling, redness, or pain at the injection site
  • Increased risk of jaundice, especially in premature infants
  • Rarely, allergic reactions or anaphylaxis

It's important for parents to discuss any concerns or questions about the use of vitamin K with their healthcare provider. In some cases, the risks of not administering vitamin K to a newborn (such as the risk of bleeding in the brain) may outweigh the potential risks of the injection.


In conclusion, vitamin K is an essential vitamin for blood clotting and bone health. It can be found in a variety of foods, including leafy greens, eggs, and meat. While vitamin K deficiencies are rare, they can occur in newborns and people taking certain medications. The recommended daily intake varies based on age and gender, and it is important to talk to a healthcare provider before taking any supplements. Vitamin K supplements are generally safe when taken as recommended, but high doses can cause side effects such as flushing and sweating. Overall, vitamin K is an important nutrient to include in a healthy diet to support overall health and wellbeing.

Vitamin K is an essential nutrient that plays a crucial role in blood clotting and bone health. Newborn babies are at an increased risk of bleeding due to a deficiency of vitamin K, as their digestive systems are not yet fully developed to absorb this vitamin from breast milk or formula.

To prevent this, vitamin K supplementation is recommended for newborns, usually in the form of an injection given shortly after birth. Vitamin K supplementation is generally safe and effective in preventing bleeding in newborns. However, parents should be aware of the rare but potential risk of developing a serious allergic reaction to the injection.
