The Cochrane Library 4/2/12: "Inositol is an essential nutrient for cells, with high concentrations in breast milk (particularly in the breast milk of mothers whose babies have been born early). A drop in inositol levels in babies with respiratory distress syndrome (RDS) can be a sign that their illness will be a severe one. Our review found that the initial evidence regarding inositol supplementation in preterm babies with RDS is promising. Supplementation lowered rates of death, bleeding in the brain, and with an important reduction in eye problems as well. Inositol did not have serious adverse effects."
