Our story
Built by two doctors. Driven by the data.
Dr. Chelsie Russig and Dr. Marjorie Albers are physicians, researchers, and breastfeeding mothers who couldn't find a vitamin D supplement that matched the evidence. So they made one.
Meet the founders
Dr. Chelsie Russig
DO
Dr. Russig is a physician and mother of two whose clinical work focuses on maternal-infant health. She has spent years reviewing the vitamin D literature and advocating for evidence-based supplementation guidance in postpartum care.
Dr. Marjorie Albers
MD
Dr. Albers is a physician, researcher, and mother of two whose interest in nutritional biochemistry led her to the landmark vitamin D studies. She is passionate about evidence based medicine and compassionate care.
Where it started
Dr. Russig and Dr. Albers met during residency and bonded over a shared frustration: the gap between what the peer-reviewed literature clearly showed and what was actually available to their patients. When both became mothers and chose to breastfeed, that frustration became personal.
They knew the Hollis et al. data. They knew the NEJM findings. A decade of rigorous research showed that a breastfeeding mother taking 6,400 IU of vitamin D3 daily could fully meet her infant's needs through breast milk alone — no drops required. The science was unambiguous. A product built around it didn't exist.
Two doctors. Two mothers. One formula the research had already written.
Our mission
Make the evidence-based choice the easy choice.
Sunlatched exists to close the gap between what the research shows and what mothers are actually offered. We believe every breastfeeding mother deserves access to the clinically-studied dose — formulated simply, tested rigorously, and designed to be used alongside her healthcare team.
What we believe
Science first
Every decision we make starts with the peer-reviewed literature. We don't extrapolate. We don't guess. We follow the data.
Radical transparency
We publish our sources. We share our testing results. We tell you exactly what's in the capsule and why.
Provider partnership
Sunlatched is designed to be used with your healthcare team, not instead of them. We build tools for providers and encourage every customer to involve their OB, family doctor, midwife, pediatrician, or lactation consultant.
Mothers deserve better
The postpartum period is one of the most demanding of a woman's life. We think the products she reaches for should be held to the highest standard.
