If you are looking for the extensive database of clinical trials / studies surrounding lactation benefits, here is our Extended List of Lactation / Nursing Benefits. If you are looking for a list of summarized findings about the benefits of lactation / nursing, then continue below.

We have organized the benefits into three overall categories:
  • Benefits of Nursing for Children
  • Benefits of Nursing for Mothers
  • Benefits of Counseling & Support on Lactation Outcomes
Within each category, the list is in no logical order. If you want to review our cited sources for further analysis, click the “Extended List” link at the top of this page.
