Similac Pro-Sensitive OptiGRO Non-GMO Infant Formula with Iron (34 oz.)

Similac is the first and only baby formula with 2'-FL Human Milk Oligosaccharides (HMOs), a unique immune nourishing prebiotic previously only found in breast milk. 2'-FL is backed by more than 15 years of extensive research and Similac Pro-Advance with 2'-FL helps strengthen baby's immune system to be more like a breastfed infant than ever before. Most prebiotics are known to support gut health (that's where 70% of the immune system exists). Similac with 2'-FL not only supports gut health, but also circulates in the bloodstream to support your baby's immune system throughout the body. Our baby formula with 2'-FL is available in two non-GMO gentle formulas: Similac Pro-Advance and Similac Pro-Sensitive.
