- BUILT ON GROUNDBREAKING TODDLER MICROBIOME RESEARCH Our My Baby Biome Study* found that 9 in 10 U.S. babies are missing Bifidobacterium strains critical for immune development in the first 1,000 days. Low levels are associated with higher rates of allergies, eczema, and asthma. Persephone was built to restore what modern life has disrupted. *Published in Communications Biology, 2025.
