Research That Starts With You

This study is led by Mommy’s Milk Human Milk Research Biorepository, part of the Department of Pediatrics at UC San Diego. We collect and study human milk to better understand how medications, health conditions, and environmental exposures affect breastfeeding parents and
their babies.

  • 100% Confidential
  • Research conducted by a trusted academic institution
  • Designed to reflect real-life experiences

We Want to Hear From You

We are especially interested in hearing from:

  • Black families
  • Hispanic/Latinx families
  • Families who qualify for programs like WIC, SNAP, or Medicaid
    Your experiences are often underrepresented in research — and that matters. Including all
    voices helps create better, fairer care for every family.
  • Currently enrolling participants in: Georgia, Kentucky, Ohio, Florida, and Washington, D.C.

Easy. Virtual. From Home.

All participation can be completed from home, and all materials are provided.

If you join, you will:

  • Complete a brief phone interview
  • Provide one breast milk sample
  • Fill out a short follow-up survey
  • Receive up to $35 in digital gift cards
  • If needed, a hand pump is included.

Be Part of Something Bigger

When families are represented in research, everyone benefits.

Your participation helps researchers:

  • Understand how real-world experiences affect breast milk
  • Improve how research studies offer compensation
  • Generate data that supports healthier futures for parents and babies

Your milk tells a story — and that story can help shape better care.


All Milk Samples Needed

All milk is welcome:

  • All exposures
  • All health conditions
  • All experiences

There is no judgment, and your participation is 100% confidential.
