Breastfeeding is best for babies and provides many benefits. It is important that, in preparation for and during breastfeeding, you eat a healthy, balanced diet. Combined breast and bottle feeding in the first weeks of life may reduce the supply of your own breast milk, and reversing the decision not to breastfeed is difficult. The social and financial implications of using an infant milk should be considered. Improper use of an infant milk or inappropriate foods or feeding methods may present a health hazard. If you use an infant milk, you should follow manufacturer’s instructions for use carefully – failure to follow the instructions may make your baby ill.

Why are HMOS important?

Breast milk is the gold standard for infant nutrition...

Good nutrition builds the foundation for a child’s ability to learn, grow and thrive. For babies, the best nutrition is breast milk – there’s nothing in the world like it.

As great as infant formulas have become, breast milk will always be the gold standard due in part to the immune support that breast milk provides.

Studies suggest that babies who are breastfed often have stronger immune systems, which may be due to the presence of HMOs.

What are HMOs?

Human milk oligosaccharides (HMOs) are special prebiotics found naturally in breast milk. They feed good bacteria in the gut. There are many health benefits associated with HMOs in breast milk, and researchers believe they may be one of the main reasons breastfeeding provides immune health benefits.

HMOs are the third most abundant solid ingredient in breast milk (after fat and carbohydrates). Previously, HMOs were only found in significant levels in breast milk.

HMOs feed good bacteria in the gut where 70% of the immune system exists. They are also absorbed into the bloodstream to support all of your baby’s developing immune system.


HMO in formula

Thanks to breakthrough research we know that a specific HMO, 2’-FL, provides numerous health benefits to growing babies and are thought to play a role in supporting the development of a strong immune system.

Being able to include this important nutrient in formula is one of the biggest advances in infant nutrition of the last decade.

Probiotics and Prebiotics

It's crucial to give your child the building blocks they need from the start. Probiotics, also known as healthy bacteria, are live microorganisms located in a person's intestinal tract. Prebiotics are not bacteria, but they provide the food source that probiotics need to survive.

This is where this unique type of prebiotic, 2'-FL, comes in. 2'-FL is the most abundant HMO in most breast milk. This prebiotic feeds the healthy bacteria in your child's gut, allowing them to work better. Having these healthy microbes or bacteria in your little one's gut is critical to their development.
