Lactoferrin, explained: the multitasking glycoprotein

Found in colostrum, studied for decades, and surprisingly hard to deliver intact.

Lactoferrin is a glycoprotein, a protein with sugar molecules attached, found naturally in milk and especially concentrated in colostrum, the first milk a mammal produces. It has been studied for decades for its role in iron binding and as part of the body’s natural defenses.

Why it comes up so often

Lactoferrin sits at an interesting intersection of immune support, gut health, and the broader healthy-aging conversation. That versatility is why you see it in everything from infant nutrition research to longevity stacks.

The delivery challenge

Like other proteins and peptides, lactoferrin is sensitive to the digestive environment, in particular to gastric pepsin, the stomach’s primary protein-cleaving enzyme. Without protection, a portion of oral lactoferrin can be degraded before absorption. Once again, the molecule is promising; the bottleneck is keeping it intact through the gut.

How peppy™ approaches it

EXTEND, our longevity ritual, is built around lactoferrin delivered through the PepBeads™ platform (designed to protect the glycoprotein through digestion) and paired with NMN, astragalus, and vitamin D3/K2. The goal is a daily lactoferrin ritual you can actually keep up with, no fridge, no needle.
