A study led by Chittaranjan Yajnik at King Edward Memorial Hospital found that vitamin B12 supplementation in adolescents improves newborn ponderal index and alters cord blood gene expression.
Background
The PRIYA trial, a follow-up to the Pune Maternal Nutrition Study (PMNS), investigated the impact of vitamin B12 and multi-micronutrients on offspring health. Researchers suggested B12 regulates methylases, enzymes involved in gene expression, and recommended including physiological doses of B12 in iron and folic acid tablets.
