Oral Supplement for Pregnant and Lactating Mothers to Promote Infant Immune Maturation and Protection Against Early Life Infections

During pregnancy mothers have to fulfill the tremendous physiological needs to support their own immune status as well as that of their babies. Accordingly, it appears highly valuable to provide mothers with a nutritional supplement during pregnancy and lactation to promote the immune development in newborns, thus reinforcing the infants' defenses.

In that respect, an appropriate maternal diet must provide sufficient energy and nutrients to meet the mother's usual requirements and promote health status, as well as the needs of the growing fetus and beyond for the neonate.

Key organogenesis steps take place during fetal life and many functional features of the immune system are already coded in the genetic asset of the individual. However, at birth the immune system remains fairly immature. An epigenetic, postnatal instruction seems to be extremely important for the maturation of the immune system allowing its full functionality.

The cross-talk between the mother and her baby is, indeed, crucial for the optimal development of the foetus and subsequently for the full and functional maturation of the neonate.

The newborn relies for his protection almost exclusively on his innate immune system that is initially instructed and educated early in life by factors derived from his mother as well as post-natal environmental factors such as early life colonization with micro-organisms that activates the innate immunity and enhance Th1-cell polarization thereby potentially reducing atopic dermatitis with respect to the hygiene hypothesis.
