Study: Vitamin D Supplementation Improves Babies’ Growth

178

Baltimore, MD–A new clinical trial from McGill University, presented at  Nutrition 2019, held at the Baltimore Convention Center in June, looked at the impact of vitamin D supplementation on infant growth. As the researchers explain in the study abstract, vitamin D status is positively associated with lean mass phenotype in healthy infants born with sufficient vitamin D stores. In this study, researchers tested whether rapid correction of low neonatal vitamin D status would improve body composition (lean mass and fat mass) at six months of age.

In the study, infants with serum 25(OH)D < 50 nmol/L (n=87) were randomized to receive 400 or 1,000 IU/d until 6 months of age. Those with 25(OH)D ≥50 nmol/L (n=31) were recruited as a reference group, and received 400 IU/d.

The result: Newborns with low vitamin D stores who were given 1,000 IU/day of vitamin D supplementation built up their D stores more rapidly and gained more lean body mass by six months of age compared to infants given 400 IU/day, which is the current standard of care for children as recommended by American Academy of Pediatrics.

  1. The women and their children both need to be exposed to regular, midday, full-body sun exposure, which can stimulate up to 20,000 IU in the skin. That way, the mothers will be replete with healthful vitamin D and many other essential photoproducts of sun exposure. And, their infants will never be born vitamin D deficient. Growth rates will then be normal, and the health and bone strength of the infants will be in normal ranges.
