Your Microbial Origins

Your first bacteria shaped your health in ways science is still uncovering:

• Vaginal delivery coats newborns in Lactobacillus, seeding the gut with protective species from the start.
• Breast milk oligosaccharides feed beneficial Bifidobacterium, not the baby itself — mothers manufacture bacterial food.
• Early exposure to pets, siblings, and outdoor play builds a more diverse, resilient immune system.
• Together, these microbes perform critical functions your own DNA cannot handle alone, from making vitamins to shaping brain chemistry.
