Similac Pro-Advance™ and Similac Pro-Sensitive™—support for baby’s developing immune system
Understanding Your Baby’s Immune System
Infants are born with certain immune protections they receive from their mothers during pregnancy. This is called passive immunity, because babies receive antibodies from their mother. Antibodies are special proteins produced by the immune system to protect the body against infection and illness.
Passive immunity is only temporary and begins to decrease after the first few weeks of life. That’s why a baby’s immune system is important for keeping them healthy. Babies begin to produce their own antibodies when they are about 2-3 months old.
Importance of Human Milk Oligosaccharides (HMOs)
Breast milk contains many important immune-nourishing human milk oligosaccharides (HMOs), which help support baby’s immune system. HMOs are the third most abundant component in breast milk (excluding water), after fat and carbohydrates.
HMOs encourage the growth of ‘good’ bacteria in your baby’s digestive tract, which is where 70% of the immune system is located. A healthy digestive system is important for a baby’s developing immune system.
Narrowing the Gap Between Breast Milk and Formula
Previously, only babies who were breastfed would have the immune-nourishing benefits of HMOs. Unlike other formulas, Similac has 2’-FL HMO, an immune-nourishing prebiotic that circulates throughout the body. The addition of 2’-FL HMO that is structurally identical to that found in breast milk is another groundbreaking step toward narrowing the gap between breast milk and formula.
Similac Pro-Advance and Similac Pro-Sensitive are the first and only Similac formulas with 2’-FL HMO, a prebiotic like that found in most breast milk. 2’-FL supports a baby’s immune system to be more like that of a breastfed infant.
For the first time, babies can get the important immune-nourishing benefits of 2’-FL HMO in a formula—only from Similac!
