Similac Advance EarlyShield® is designed to be more like breast milk and help support your baby's developing immune system. Only EarlyShield has our exclusive blend of immune-supporting nucleotides — and prebiotics and carotenoids, nutrients naturally found in breast milk. Explore how EarlyShield can help give your baby a strong start.

Nucleotides to Help Support the Immune System

Nucleotides are immune-supporting nutrients that help increase your baby's ability to make important antibodies. The nucleotide blend and level in Similac Advance EarlyShield is designed to match the nucleotides in breast milk.

Prebiotics to Help Promote Digestive Health

Your baby's gut relies on millions of "good bacteria" to support digestive health. Recent clinical research suggests that special carbohydrates (prebiotics) found in breast milk and Similac Advance EarlyShield can help stimulate the growth of these beneficial bacteria, which helps support the immune system.

Carotenoids Naturally Found in Breast Milk

Carotenoids play important roles in the body. Similac Advance EarlyShield has our unique blend of carotenoids, including lutein (found in spinach), lycopene (found in tomatoes), and beta-carotene (found in carrots), which are found in breast milk. These carotenoids help support certain cells in the body, such as the eyes.
