Breast milk doesn’t skim the fat, so why would we?

Healthy fats are essential for baby's body, brain, and every squishy part in between—just one of the (many) reasons we only use organic, grass-fed whole milk—never skim.

**Every American-made* infant formula contains skim milk...except one.**

We're proud to be considered outliers in a sea of sameness as the only infant formula that uses organic, grass-fed whole milk.

*With globally-sourced ingredients

Whole milk’s got the good stuff.

Which is why ByHeart is made with only organic, grass-fed whole milk (without a drop of skim).

FOR BRAIN DEVELOPMENT
Whole milk is full of delicious healthy fats like naturally-occurring MFGM—a complex blend of fats and proteins also found in breast milk. It’s crucial for baby’s brain development and growth (and has also been associated with a healthy microbiome).

FOR EASY DIGESTION
Whole milk has plenty of easy-to-absorb fatty acids which helps keep baby’s poops softer.

FOR EYE HEALTH
Whole milk contains over 5x as much lutein (a naturally occurring antioxidant beneficial for eye health and cognitive function) as skim milk.

FOR IMMUNE SUPPORT
Whole milk has 3.5x times the amount of beta-carotene as skim, which converts into Vitamin A—an essential vitamin for a strong immune system.

FOR THE ENVIRONMENT
Grass-fed milk has more Omega-3s than conventional milk, and these cows require less water than grain-fed cows.

Never compromising on ingredients or standards.

Would you want an infant formula with ingredients from 1915?

Back then, infant formula was made with skim milk and called "synthetic milk adapted" (just rolls of the tongue, huh?). The world has changed a ton in the last 110 years, but over 90% of infant formula sold in the US is still made with skim milk—even in 2024, when the global consensus is that healthy fats are essential for a baby's brain development and growth.
