Supporting immunity beyond the microbiota
Microbiota-independent immune-supporting effects have also been reported for ingredients like lactoferrin, milk fat globule membrane (MFGM), 2’-FL and polyunsaturated fatty acids such as docosahexaenoic acid (DHA) and arachidonic acid (ARA).
Lactoferrin, a natural iron-binding milk glycoprotein, has been found to help the development and maturation of the gut during early life

presumably via multiple mechanisms of action: by binding iron, which is essential for viability of several pathogens; by directly inactivating pathogens; by blocking receptors for pathogens on epithelial cells; and by immuno-modulatory effects via direct interactions with gut epithelial cells and immune cells

Consisting of phospholipids, cholesterol and glycoproteins, the tri-layered membrane surrounding milk fat droplets in human and bovine milk is known as the MFGM. Whey-based MFGM ingredients have been shown to support immune function: a reduced prevalence of diarrhoea

and reduced episodes of middle ear infection

were observed in clinical trials studying infants. As a combination, lactoferrin and MFGM supplementation resulted in a lower incidence of upper respiratory tract infections and diarrhoea

A good immune response against pathogens that adhere to, and pass through the intestinal barrier and cause infections, is of key interest for infant immune health. 2’-FL can serve as a decoy receptor

. These data suggest that GOS and 2’-FL have a direct inhibitory effect on pathogen infection, shedding light on the role of oligosaccharides in supporting immunity in early life.
The long-chain polyunsaturated fatty acids (LCPUFAs) DHA and ARA like those in our microencapsulated Vana-Sana™ range, can potentially help to modulate immune responses in infants
