Dynamic metabolic signatures of choline and carnitine across healthy pregnancy and in cord blood: Association with maternal dietary protein

Congrats to Meera and Zach on their most recent publication exploring the importance of choline and carnitine during fetal development. They discovered that despite inadequate choline intake, serum free choline was elevated in late pregnancy and enriched in cord blood compared to maternal serum. Serum carnitine declined in late pregnancy despite a high protein diet. The higher cord:maternal concentrations in choline and carnitine metabolites suggests active uptake in late pregnancy.
