Breast milk is our blueprint.

Breast milk is nature’s gold standard, but it doesn’t work for all parents, or at least, not all the time. That’s why we spent over five years obsessing: studying its nutrients, analyzing its unique benefits, and innovating on the most up-to-date breast milk research and nutrition science.

Protein

Inspired by breast milk

Our proprietary protein blend combines the two most abundant proteins in breast milk (alpha-lactalbumin–the first formula in the US to provide it at breast milk levels–and lactoferrin); easy to digest, pre-broken down proteins; and a whey to casein ratio that mirrors that of early breast milk.

  • Easier digestion
  • Less spit up
  • Immune system support

Essential Fats

Whole Milk Plus

As the first US infant formula to add organic, grass-fed whole milk to our blend, we can ensure that baby gets a unique balance of important fats, including essential fatty acids as well as additional vitamins and antioxidants. While other formulas rely on skim milk, which removes good fats, we keep in what we believe is best for baby.

  • Contributes to cognitive development
  • Supports calcium absorption
  • Promotes eye health

Carbohydrates

From Lactose to Energy

Just like breast milk, our formula uses lactose (sourced from organic milk) as its primary carbohydrate (energy for baby to grow!), rather than added glucose like some other formulas (think: corn syrup and maltodextrin), which can change the composition of the gut microbiome. Lactose, and our lactose-derived prebiotic GOS, help keep baby’s gut balanced and digestion smooth, and supports nutrient absorption.

  • Softer and more frequent stools (AKA a happy tummy!)
  • Supports good bacteria in baby’s gut

Our “No” List

We work directly with every one of our suppliers to set a new standard for quality, and for contaminant control. Our rigorous vendor requirements and control over every step of manufacturing in “The ByHeart Kitchen” (our owned and operated facility in Reading, PA), has allowed us to keep plenty out of the recipe… because we have to do better for babies.
