  • The National Institutes of Health (NIH), a part of the U.S. Department of Health and Human Services, is the primary Federal agency for conducting and supporting medical research.

    NIH is the steward of medical and behavioral research for the Nation. Its mission is science in pursuit of fundamental knowledge about the nature and behavior of living systems and the application of that knowledge to extend healthy life and reduce the burdens of illness and disability.

    Helping to lead the way toward important medical discoveries that improve people’s health and save lives, NIH scientists investigate ways to prevent disease as well as the causes, treatments, and even cures for common and rare diseases.

    NIH research impacts:
    • child and teen health,
    • men's health,
    • minority health,
    • seniors' health,
    • women's health, and
    • wellness and lifestyle issues.
    Composed of 27 Institutes and Centers, the NIH provides leadership and financial support to researchers in every state and throughout the world.

    For over a century, the National Institutes of Health has played an important role in improving the health of the nation.
