Got milk?
Your milk is more than nutrition. It's knowledge. Join one of our studies to help us unlock the undeniable power of human milk.
OUR RESEARCH
The Milk Storage Study
Help us learn what really happens to human milk when it's stored. In this study, you will:
- Provide 4oz of freshly pumped milk for us to test across multiple storage conditions
- Complete a short questionnaire about your diet, pumping routine, and storage setup
Participants receive a $25 Amazon gift card as a thank you.
The Taste Test
Help us understand how the taste of breast milk changes in different storage conditions. In this study, you will:
- Taste three samples: fresh, refrigerated for 4 days, frozen for 7 or 30 days
- Review each sample treated with our stabilizer solution, a placebo, or left untreated
- Complete a short survey after every tasting session to capture taste, smell, and feel
Participants receive a $75 Amazon gift card.
The Home Fresh Test
Try out our new at-home test strips tool that make milk freshness visible. In this study, you will,
- Use different test strips before storing milk and before feeding baby
- Record results across multiple samples in our app
- Complete short, weekly surveys on your experience
Your feedback will help us understand how parents use these new milk diagnostic tools.
Got a stash? Put it to work.
We're studying how freezing milk impacts nutrients, enzymes, and freshness over time, and we could always use your donation.
