Singleton pregnancies being diagnosed of fetal growth restriction from 24 to 32.6 weeks of gestation will be randomized to two equally sized groups: maternal oral supplementation with Lactoferrin and DHA (Docosahexaenoic acid) or placebo.

Randomized controlled trial among pregnant women that have been diagnosed of fetal growth restriction. These women will be randomized in order to evaluate the impact of maternal supplementation with Lactoferrin and DHA on the neurodevelopment outcome of their babies.

Main hypothesis: a prenatal intervention based on maternal supplementation with Lactoferrin and DHA improves neurodevelopment in fetal growth restriction.

Secondary hypothesis are that a prenatal intervention based on maternal supplementation with Lactoferrin and DHA in fetal growth restriction improves fetal growth and improves perinatal morbidity and mortality.
