Immune Boosting Vitamins and Nutrients for Children

Early in life, your child’s naïve immune system is challenged as he/she is exposed to a large array of bacteria, viruses and foreign substances in the environment.1,2 A healthy immune system is the best ally your child can have to fight those during his/her development.3,4 

Certain nutrients and vitamins can help support your child’s immune system:


(Such as Bifidus BL)

Good gut bacteria such as Bifidus BL support your infant’s immune system.5,6


VITAMINS A, B6, C, D, Copper, Iron, Selenium and Zinc

VITAMINS A, B6, C, D, Copper,
Iron, Selenium and Zinc

Contribute to the normal function of the immune system for infants and young children.7,8

Human Milk Oligosaccharides

Human Milk Oligosaccharides

They educate the developing immune system, strengthen the gut barrier, act as food for the growth of good gut microbiota, and trap pathogens, which may reduce the risk of infections.9-11

Human Infants receiving a Growing-up Milk like NANKID® Optipro gets the benefits of HMOs. In babies, HMO containing formula vs. an identical formula without HMOs had significantly fewer reports of bronchitis, lower respiratory infection, and use of medication.9
