9 out of 10
U.S babies are born without the essential levels of critical gut bacteria they need to build a thriving microbiome.
For generations, babies were born with a resilient gut microbiome, rich in protective bacteria that support immunity, digestion, and development.
Our study indicates that’s no longer the norm.
Without these critical bacteria, babies face a higher risk of:
Your baby deserves better bacteria
The fix for missing bacteria is probiotics. But most probiotics contain antiquated, white-label strains that are heavily manufactured. The world has changed, and those probiotics simply can’t do what needs to be done.
Our Breakthrough
A first-of-its-kind combination of prebiotics & probiotics
Rewilding the gut isn’t a job for just any strain. We deployed cutting-edge science and thoughtful precision to restore what’s been lost. Our infant and toddler synbiotic is built for today’s world, not outdated assumptions.
Our strains are effective because they’ve evolved together

Our innovative synbiotic is built on modern science and modern strains, not vintage bacteria
I had studied the microbiome for over a decade, but it wasn’t until I became a mom that I realized what was missing in our babies.
Conversations with the leading pediatric experts and the results of our My Baby Biome study revealed a shocking global trend: most babies lack the gut microbes they need for lifelong health.
I was shocked that no one had solved this problem.
So I am. This isn’t just my company, it’s my calling.
I created Persephone to bring today’s science to the families who need it most, starting in the gut. Every baby deserves the chance to thrive, as nature intended.
