ByHeart sold its FDA-approved formula to customers in all 50 states within a week of launch and they are planning on expanding the plant, Funt and Belldegrun said.

ByHeart’s founders say they are only the fourth vertically integrated infant formula brand in the United States with end-to-end oversight of production, a stable supply chain, and research and development. ByHeart processes raw, whole milk from dairy farms, turns it into powder formula using a patented blend of the two proteins in breast milk, alpha-lactalbumin and lactoferrin, as well as broken down proteins, and gets the closest to breast milk in the market, the founders said.
