The first and only clinically proven probiotic for babies.7

  • The Situation: 9 out of 10 babies lack B. infantis
    The good bacteria B. infantis is missing from baby's gut. C-sections and antibiotics have interrupted the transfer of this good bacteria from mom to baby during childbirth. 
  • The Concern: Increase antibiotics and increased C-sections
    Without B. infantis in baby’s gut, bad bacteria can thrive – particularly those linked to a higher risk of autoimmune and metabolic issues like colic, eczema, allergies, diabetes, and obesity.
  • The breakthrough: Before Evivo and after Evivo baby probiotic
    Only Evivo is clinically proven7 to restore B. infantis to baby’s gut and reduce bad bacteria that is linked to a higher risk of health issues, now and later in life.
