The world’s 1st formula with HMO that strengthens immunity, and 10 key brain nutrients for faster learning.

HMOs can help build a healthy immune system.

HUMAN MILK OLIGOSACCHARIDES, also known as HMOs, are a very special type of prebiotics found in human milk. In fact, they are the third largest solid component of human milk after carbohydrates (lactose) and fat. The HMOs found in human milk support your growing child’s digestive system.

And because 70% of the immune system exists in the gut, keeping your little one’s digestive system healthy also means strengthening their immunity.4

How does HMO work?

There are 3 ways by which HMOs help strengthen your child's immune system. 5

1 First, HMOs serve as food for good bacteria in the gut. When beneficial bacteria are properly nourished, they can grow, multiply, and fight off bad bacteria. Good bacteria also produce short-chain fatty acids that strengthen the immune system further.

2 Second, HMOs act as decoys that prevent bad bacteria from attaching to gut cells thus preventing them from entering your child's system.

3 Third, some HMOs are also absorbed into the bloodstream where they can trigger immune cells to release protective factors, regulate allergies or infections in children. So, HMOs deliver an immunity boost beyond the gut.

With HMO, you can worry less about your kid falling sick and focus more on their cognitive progression.
