Vitamin K Shot: Separating Science from Social Media Myths

Why do newborns get a vitamin K shot—and why has it become the center of so much misinformation online?  If you’ve ever hesitated about this newborn standard, this is the episode that brings clarity and calm.

In this episode, I welcome Dr. Jessica Knurick who has a PhD in Nutrition Science to break down the real reason this shot is recommended at birth, the science behind preventing Vitamin K Deficiency Bleeding (VKDB), and where social media gets it wrong. From safety concerns to conspiracy theories, we’re cutting through the noise with evidence, history, and a healthy dose of common sense.

We discuss: 

• Why the vitamin K shot is critical for preventing dangerous bleeding in newborns.

• The science behind VKDB and how misinformation spreads online.

• Evidence-based answers to common myths about vitamin K shot ingredients and safety.
