Immune Support

Children could have 3-8 cold infections a year, and adults 2-4 colds annually.5a

2 in 3 children between 6 months and 2 years of age are not eating food that supports their rapidly growing bodies.6a

Eating a healthy, balanced diet is critical for a strong immune system and overall wellbeing, but sometimes we may need some support when the system becomes strained.  When our immune systems are compromised, we are more prone to infections such as colds and flu, and it is even harder to fight these infections.6a,7a,b,c

We know that vitamins and minerals are crucial for a healthy immune system but as we find the cells representing almost 70% of our entire immune system in our gut, this seems to be a very important place to start. 9a

Immunity from gut bacteria

Our gut is the home of many beneficial bacteria, that interact with our immune cells to make sure that our immune system matures and functions correctly.  The bacteria’s effect on the immunity continues during our lifetime and has a significant impact on whole-body health. 10a,b An imbalance of beneficial bacteria and pathogenic bacteria or a loss of good gut bacteria, however, leads to reduced immunity.10c

Immunity from Vitamins and Minerals

Vitamins play a significant role in building immunity, and these include vitamins A,C,D,E,B6,B12 and folate.  Together with the trace elements selenium, zinc, and iron they contribute to the body’s natural defences on three levels by supporting physical barriers (skin/mucosa), cellular immunity and anti-body production.16a
