The only infant probiotic clinically proven to reduce bad bacteria.7

  • The Situation
    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
    Without B. infantis in baby’s gut, bad bacteria can thrive – particularly those linked to a higher risk of issues like diaper rash, colic, eczema, and allergies.
  • The Breakthrough
    Evivo is the only clinically proven7 probiotic of its kind 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.
