Folic acid supplementation is recommended during pregnancy and lactation to support infant growth and development.
Yet it increases levels of unmetabolized folic acid in human milk, prompting researchers to ask:
A study investigating these questions by comparing the effects of both folate forms has just been published in the European Journal of Clinical Nutrition. The authors did not observe a difference in impact on HMO composition between supplementing with folic acid versus 5-MTHF; however, increased unmetabolized folic acid in human milk was associated with lower concentrations of total HMOs and 3’-sialyllactose.
“This study is one step towards understanding how modifiable factors impact HMOs; furthering this understanding can support infant health, as it may enable targeted interventions that can shift human milk composition towards a more favorable profile,” writes lead author Dr. Kelsey Cochrane, PhD, University of British Columbia.

Kelsey received a Trainee Expansion Program (TEP) grant in 2021, which enabled her to travel to the University of California San Diego and gain specialized HMO research training with Dr. Lars Bode.
