What Is Colostrum? (And Why It’s Not Just for Babies)

When people first hear the word colostrum, they often ask
"wait, isn't that just for newborns?"
Fair question — and we’re here to break it down.

Colostrum, Explained

Colostrum is the first form of milk produced by mammals after giving birth. It’s loaded with nutrients, antibodies, and growth factors that help newborns transition from the womb to the outside world.

Most people associate it with breastfeeding — and they’re not wrong. But what’s lesser known is that bovine colostrum (from cows) can also offer powerful health benefits to adults.

So… It Can Benefit Adults Too?

Absolutely. According to Dr. Michael Roizen, Chief Wellness Officer at the Cleveland Clinic, bovine colostrum could be considered “nature’s original superfood.”

As quoted in The List:

"Colostrum contains numerous antibodies, growth factors, immune factors, and nutrients that can help jumpstart gut function, support the immune system, and promote a healthy microbiome."

Cows — unlike humans — can’t pass immune factors to their calves during pregnancy. That’s why bovine colostrum contains a higher concentration of immune-supporting components like IgG, making it incredibly potent for supplementation.

Dr. Roizen highlights colostrum’s role in:

  • Strengthening the immune system
  • Supporting gut health
  • Aiding respiratory function

The Science Isn’t New

Colostrum’s health benefits have been documented as far back as the 1940s — and today, clinical studies continue to explore its role in anti-aging, gut repair, immune support, and athletic recovery.
