Similac Pro-Advance contains 2’-FL Human Milk Oligosaccharide, an immune-nourishing prebiotic previously only found in breast milk. The 2’-FL prebiotic is backed by more than 15 years of extensive research.

For Immune Support

The 2’-FL HMO prebiotic circulates throughout the body. HMOs generally, feed good bacteria in the gut where 70% of the immune system is. Similac with 2’-FL HMO helps strengthen your baby’s immune system to be more like the breastfed infant than ever before. This formula is non-GMO and filled with the nourishment you’ve come to expect from Similac.

Exclusive Blend of Nutrients

OptiGRO is the exclusive blend of DHA, Lutein, and Vitamin E - important ingredients found in breast milk. While DHA supports brain development and Lutein supports eye health, Vitamin E supports developing cells.
