Prenatal vitamin D status and respiratory and allergic outcomes in childhood: A meta-analysis of observational studies.

What It Covers

This meta-analysis looks at Vitamin D, K2, Magnesium and Zinc.

A systematic review and meta-analysis were conducted on the association between 25-hydroxyvitamin D [25(OH)D] levels in maternal blood in pregnancy or cord blood at birth with the risk of offspring's respiratory and allergic conditions.
