Inspired by the science of mother’s milk where nutrient levels change between day and night, HAPPi is Australia’s first toddler milk system to nutritionally adapt by time of day.

The Happi Day and Night milk system is based on over 200¹ years of combined scientific research that explores the circadian rhythm.

In humans, the circadian rhythm follows a 24 hour cycle. It is like an internal clock that controls our ability to sleep at night and be alert during the day. Research shows some nutrients in cow’s milk² and human milk³ also have day and night cycles.

These nutrients are important for a child’s brain development, helping them learn and play by day, and turn learning into memories at night.

Together, HAPPi Day and Night provide advanced nutrition at the right time to help you child develop to their full potential.

What is Lactoferrin?

The word says it all – “Lacto” (meaning milk) “ferrin” (meaning iron) is an iron containing protein found in the human immune system and also found in milk. It works in many unique yet complementary ways to support your body at all life stages.

High levels of lactoferrin protein are found in breast milk and colostrum, the very early milk. In fact, lactoferrin is the second most abundant whey protein in breast milk. Beyond early childhood, the major dietary source is cows milk. 

Lactoferrin is well known to researchers studying human health. Since it’s discovery, cows milk lactoferrin has been the subject of over 2000 scientific studies. This includes over 80 human clinical trials, making it one of the most scientifically studied proteins in the world.
