A Formula 5 Years in the Making

Like breast milk, infant formula has to be a magical superfood that gives baby everything he or she needs. That’s why we spent over 5 years working to make the best possible first formula for baby.


The Beginning

Ron Belldegrun and Mia Funt realized that the infant formula industry needed to do better for babies. Breast milk research was moving faster than new product innovation, with three companies owning approximately 90% of the market.

Together, they embarked on (what would become) a five-year journey to baby’s first food—with no compromises.

2016 - 2017

Building an Ecosystem of Experts

We recruited world-class doctors, pediatric researchers, seasoned formula experts, dedicated blendmasters, quality obsessives, regulatory veterans, data wonks, storytellers, designers, and passionate parents.

2017 - 2018

R&D, More R&D, and...Manufacturing!

Our team began to grow, applying leading research to our unique formulation. We built quality systems and supplier approval requirements from the ground up, traveled the world for like-minded ingredient and farm partners, and refined our small batch approach to ensure we knew how to retain the quality and benefit of every ingredient.

April 2019 - June 2021

Clinical Trial

We embarked upon the largest clinical trial by a new infant formula brand in over 25 years, and even included a breast milk reference arm to ensure our nutrition (and the benefits it offers) holds up to nature’s gold standard, rather than to just another formula on the market.

Creating Our Facility

We realized that in order to create the formula of our dreams, we needed to customize our facility to our proprietary process. So we acquired a manufacturing facility in Reading, PA, and upgraded it to provide the very best conditions for our brand new infant formula— becoming only the 4th fully integrated, FDA-registered infant nutrition brand in the US (and the first new one in decades!).

Clean Label Project Certification

Our dedication and hard work set a new standard for quality sourcing and manufacturing. Our Whole Nutrition Infant Formula was given the first-ever Clean Label Project Certification for an infant formula in the US (and won their highest tier “Purity Award,” too).

July - October 2021

Clinical Trial Results

We got the results to see how our formula measured up against both formula-fed and breast-fed babies— and they were as spectacular as we had hoped.
