It’s the only soy formula clinically shown to help support the developing immune system, similar to infants fed human milk or milk-based formula.* Our gentle, soy formula is specially designed for babies with lactose intolerance and galactosemia.

  • VEGETARIAN FRIENDLY: For infants and children from families who follow a vegetarian diet
  • SOOTHES SENSITIVE TUMMIES: Our milk-free, lactose-free formula is nutritionally complete and easy-to-digest, with the gentleness of soy to soothe baby’s tummy
  • IMMUNE SYSTEM SUPPORT: Similac Soy Isomil infant formula has prebiotic FOS and is the only soy formula clinically shown to help support the developing immune system, similar to infants fed human milk or milk-based formula*
  • SUPPORTS BRAIN & EYE DEVELOPMENT: Features our exclusive blend of DHA, lutein, and vitamin E, special ingredients found in breast milk, to support baby's brain and eye development

If your baby has fussiness or gas, ask your physician about switching to Similac Soy Isomil. Soy formulas are not recommended for premature infants with birth weights of less than 1800 g.
