Our patented protein blend gets closest to breast milk.
The #1 protein
in breast milk.
We’re the first and only US-made infant formula brand to add alpha-lac at breast milk levels. Research suggests that this growth-supporting protein supports easier digestion. Plus, it’s high in tryptophan (the amino acid in turkey that makes you sleepy!)—which has been shown to help babies fall asleep faster.
The #1 protein
Early breast milk is filled with lactoferrin (which is rarely added as a unique ingredient to infant formula). Lactoferrin supports baby’s immune system and gut health. It also aids in iron absorption, which is a critical mineral for baby’s development.
Whole + partially-broken down proteins
A nutritious blend that’s gentle on tummies.
Whole proteins are full of nutrition, but may be harder to digest, while broken down proteins are easier-to-digest but don’t deliver all the benefits of whole proteins. Most formulas use one or the other. Breast milk has both, and so do we.
The only US-made infant formula company to use organic, grass-fed whole milk, not skim.
Whole milk is full of healthy fats—and breast milk is too! Research shows that whole milk fats (such as naturally occurring MFGM) play an important role in baby’s brain development and growth.

My baby went back and forth between ByHeart and breast milk beautifully!”
The only formula I will ever buy again if I can help it.”
Amazing formula: Started my 3 month old on this and he has been tolerating great! Soft poops everyday, less spit up! Will never use another formula!”
ByHeart is literally a God send!”
We got the ByHeart formula and when I gave it to my 7 months old baby she drank an 8oz bottle of it and I'm talking CHUGGED it.”
Because there’s no such thing as other people’s babies.
