Breast milk is best for your baby.

Health Canada, the Canadian Paediatric Society, and the Dietitians of Canada recommend that you exclusively breastfeed your baby for the first 6 months and that you continue to breastfeed for up to 2 years or longer along with complementary foods.

Human Milk Oligosaccharides

Lightbulb

Did you know?

Babies are born with an immature immune system that develops during the first few months of life. The mother protects her baby during this transition with components transferred in her breast milk, such as human milk oligosaccharides (HMOs).1

What are HMOs?

Breast milk contains many protective factors that help build the baby’s immune system.
These include complex carbohydrates called human milk oligosaccharides (HMOs).2-5


HMOs are the third most abundant component of breast milk (excluding water).6,7

Similac Pro-Advance® Baby Formula - The first and only infant formula with 2’-FL* in Canada.

What is 2’-FL?

Of all the HMOs that have been identified in breast milk, 2’-fucosyllactose
(2’-FL) is the most abundant and is found in the milk of most mothers.8

What do HMOs, like 2’-FL, do?

About 70% of the immune system is found in the digestive tract9, so maintaining a favourable environment for beneficial bacteria in the gut can help babies build strong digestive and immune systems.6 HMOs, like 2'-FL, in breast milk can affect the baby's immune system in various ways:6

  • 2’-FL feeds good bacteria in the baby’s gut

    Feed the good bacteria
    in the baby’s gut
    (prebiotics)

  • 2’FL protects against harmful bacteria in the baby’s gut

    Protect against
    harmful bacteria
    in the baby’s gut

  • 2’FL supports the baby’s developing immune system

    Support the baby’s
    developing immune
    system

Immune Support Innovation: 2’-FL†

SimilacPro-Advance LogoProduct Family + Mild Drop-freLearn more

2’-FL is backed by 20 years of research and was previously only available to breastfed babies. 2’-FL oligosaccharide†, a new and innovative ingredient, is now available to formula-fed babies who are nourished with Similac Pro-Advance®.


In a clinical study, parents who fed their babies Similac® with 2’-FL† reported 3 times fewer respiratory infections compared to parents whose babies were fed infant formula without 2'-FL.10,11†‡


Similac Pro-Advance® — Our most advanced and closest formula to breast milk.


The first and only baby formula with 2’-FL† in Canada.

† Not derived from human milk; identical structure to 2’-FL found in breast milk.
