5 things to think about when choosing a formula for your baby

Formula should be easy to digest.

Breast milk is naturally easy-to-digest, shouldn’t all formulas be too? We thought so, and think the 50% of babies who switch baby formulas (often because of this issue) probably agree. That’s why we designed a patented protein blend that gets closest to breast milk—with the 2 most abundant proteins found in breast milk, plus broken down proteins—all for a blend that’s clinically proven easy to digest.

Milk fat really matters.

When searching for baby formula you’re bound to find skim milk more often than not. Unlike skim, whole milk is full of natural, healthy fats that help support baby’s cognitive development and growth. And we’re proud to be the only US-made* infant formula to use organic, grass-fed, whole milk.

*With globally sourced ingredients

Small batch blending makes a big difference.

Our small batch process minimizes the time it takes to produce our formula in order to protect the integrity of the (healthy!) fats. Exposing these fats at a high heat for an extended period of time can actually impact the color, taste, texture and smell of the formula. Less time + less heat = small batch goodness.

Real innovation requires a new clinical trial.

Did you know new clinical trials are not required for infant formula if a brand is using an old recipe (and not making any changes to it)? And that to create a new innovative infant formula, a company has to run their own? That’s why we ran the largest clinical trial by a new brand in 25 years—including 311 babies over 6 months and even compared our formula to breast milk (we’re actually the only new infant formula to do that).

Clean ingredients are not enough.

Anyone can say they’re “clean”, but you have to go a lot further to be certified-clean*. Not only do we directly source our ingredients from suppliers we personally know and trust—we’re proud to be the first infant formula company to receive Clean Label Project’s highest-tier Purity Award (and test for 700 contaminants, versus the required 400).

Our Magic Ingredient?

All of them. We’re proud to include:

Organic, Grass-Fed Whole Milk—Not Skim

With delicious, healthy fats like naturally-occurring MFGM (a complex blend of fats and proteins that’s crucial for baby’s brain development and growth).

Patented Protein Blend

Our proprietary, closest-to-breast-milk blend features the 2 most abundant proteins found in breast milk, plus easy-to-digest broken down proteins.

Organic Prebiotics

Our lactose-derived, prebiotic GOS helps support the growth of good bacteria in baby’s gut (and keeps baby’s poops softer!).

Carbs From Lactose

Just like breast milk, our formula uses lactose as its primary carbohydrate, instead of corn syrup or maltodextrin.

Plant-Based DHA & ARA

DHA is a key omega-3 fatty acid found in breast milk. Research shows it supports brain function and eye health. (PS: Ours is from algae!)
