Similac Pro-Advance helps strengthen your baby’s immune system to be more like a breastfed baby than ever before. How? Similac with 2’-FL helps support baby’s developing immune system by closing multiple gaps in immune function* between formula-fed and breast-fed infants. Unlike other formulas, Similac has 2’-FL HMO, a prebiotic that circulates throughout the body. Similac’s biggest breakthrough in nearly a decade comes in two gentle formulas: Similac Pro-Advance and Pro-Sensitive.
