Main study aim

To determine whether maternal prebiotic supplementation during pregnancy and breastfeeding can reduce the development of eczema in babies.

Additional study information

Prebiotics are a type of fibre that occur naturally in foods such as whole grains, vegetables and legumes. They are called ‘prebiotics’ because they are digested by gut bacteria, but are different from ‘probiotics’ which are the actual ‘friendly bacteria’. Participating women will be asked to consume a prebiotic or placebo powder daily, from mid-pregnancy until their baby is 6 months old.

Study population

Pregnant women, less than 21 weeks gestation, whose baby-to-be has a mother, father or sibling with a history of medically diagnosed allergic disease (asthma, allergic rhinitis, eczema and/or food allergy).

Study status

Recruitment closed.
