Vitamin D and human lactation

A Fairney, E Naughten, T E Oppé

    Lancet (London, England)
    |October 8, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Breastfeeding mothers show higher serum vitamin D levels than non-breastfeeding mothers. Lactation itself did not significantly alter vitamin D levels, suggesting no need for supplementary vitamin D during breastfeeding.

    Area of Science:

    • Nutritional biochemistry
    • Maternal and infant health

    Background:

    • Vitamin D is crucial for bone health and immune function.
    • Maternal vitamin D status can impact both the mother and infant.
    • Understanding vitamin D dynamics during lactation is important for infant nutrition.

    Purpose of the Study:

    • To compare serum 25-hydroxyvitamin D concentrations in breastfeeding versus non-breastfeeding mothers.
    • To assess the impact of lactation duration (4-6 weeks) on vitamin D levels.
    • To determine if lactation necessitates vitamin D supplementation.

    Main Methods:

    • Measurement of circulating serum 25-hydroxyvitamin D.
    • Comparison between recently delivered mothers who were breastfeeding and those who were not.
    • Assessment at baseline and after 4-6 weeks of lactation.

    Main Results:

    • Breastfeeding mothers exhibited significantly higher basal serum 25-hydroxyvitamin D levels compared to non-breastfeeding mothers.
    • Serum 25-hydroxyvitamin D levels did not change significantly between baseline and 4-6 weeks postpartum in the breastfeeding group.
    • No significant difference in vitamin D levels was observed between the 4-6 week and basal measurements within the breastfeeding group.

    Conclusions:

    • Breastfeeding mothers naturally maintain higher vitamin D levels.
    • Lactation does not appear to deplete maternal vitamin D stores significantly.
    • Current evidence does not support routine vitamin D supplementation solely based on breastfeeding status.
