ByHeart Formula Review: The Clean Formula Moms Are Loving

Figuring out the world of baby formula can feel overwhelming. And if you’re anything like me, you’ve probably spent late nights Googling ingredient lists, scrolling through reviews, and wondering what’s actually the best option for your baby. There’s no shortage of opinions, societal pressure, and mom guilt when it comes to how we feed our babies. Add to that the endless options and information, and finding the right formula can feel like an uphill climb, even though all you want is the best choice to give your baby a good start in life.

With my first baby, I went all-in researching European formula companies because they seemed to have stricter ingredient standards than many U.S. ones. But when my second baby came along, I wanted something just as high-quality that was more readily available. Enter ByHeart—a new(ish) U.S-based formula that’s getting a lot of buzz for its clean ingredients and thoughtful approach to infant nutrition.

While I didn’t personally use ByHeart with my babies (ByHeart was on a shipping freeze when my daughter was a baby), I love seeing new, innovative brands shake up the formula industry. 

After diving into the details, I wanted to share everything I’ve learned about ByHeart to help you decide if it’s the right fit for your family. And I’ll break it all down just like I would for myself—ingredients, safety, cost, and everything in between.

 

What is ByHeart formula?

ByHeart is a next-generation infant formula designed to closely mimic breast milk. It’s made with organic, grass-fed whole milk (not skim) and a patented protein blend that matches the levels of the #1 protein found in breast milk.

ByHeart really stands out for how much care goes into every detail. It’s earned the Clean Label Project Purity Award, which means it’s tested for over 700 contaminants—way more than the usual standards. And fun fact: ByHeart also ran one of the biggest clinical trials for infant formula in the last 25 years. The results? It’s not just well-made—it’s clinically proven and even includes a direct comparison to breast milk, which is pretty rare!

ByHeart infant formula review

When I first started looking into ByHeart, one of the first things I was really struck by was how intentional their approach is—from the ingredients to the science behind it. As a mom who’s spent countless hours dissecting labels when I decided to breast and formula feed, I know how much it matters to feel confident in what you’re giving your baby.

Let’s break it down—what’s inside, how it’s made, and whether it lives up to the hype. Here’s everything you need to know about ByHeart, so you can decide if it’s the right choice for your family.

Ingredients

ByHeart formula is made with organic, grass-fed whole cow's milk—the first U.S. infant formula to include it—and it’s designed to be as close to breast milk as possible. As a mom, here’s what makes it stand out IMO:

1. Patented protein blend: Their formula includes type of proteins found in breast milk to help with growth, digestion, and immune health.
2. Whole milk benefits: Unlike skim milk, whole cow milk is naturally rich in healthy fats for brain development, eye health, and immune support.
3. Lactose as the primary carbohydrate: Uses lactose instead of added sugars like corn syrup.
4. Brain-boosting nutrients: Includes plant-based DHA and ARA to support brain and eye development.
5. Prebiotics for gut health: Promotes good gut bacteria and helps keep baby’s poops soft—closer to breastfed poops.

I definitely appreciate that ByHeart keeps things clean and simple, and avoids unnecessary additives and extra ingredients like palm oil or glucose syrups. 

Safety

Even though I’m out of the formula stage with my kids, I know how important it is to feel confident about what you’re feeding your baby, which is why I love sharing trusted, good options with the NMM community. ByHeart goes above and beyond with their quality and transparency. Here are a few ways they do that:

1. Exceeding testing standards: ByHeart tests for over 700 contaminants, far surpassing the requirements for the Clean Label Purity Award.
2. Trusted ingredients: Handpicked from suppliers who share their core values and commitment to quality.
3. Small-batch production: Blended in small batches across their US-owned factories in Iowa, Pennsylvania, and Oregon.
4. End-to-end manufacturing: ByHeart controls every step of the process as the first new US infant formula manufacturer in 15 years.
5. Certified excellence: The only US formula brand to earn the Clean Label Project’s First 1,000 Day Promise Certification for rigorous contaminant testing.

ByHeart formula review: pros & cons

What moms are saying about ByHeart

Parents have a lot of love for ByHeart formula, and it’s easy to see why. Moms rave about the clean ingredients, how gentle it is on their babies’ tummies, and the peace of mind they feel knowing they’re feeding their little ones something safe. Here are a few highlights:

1. “ByHeart has been such a lifesaver for us. When our baby wasn’t gaining weight, ByHeart became a necessity. Within a week of combo feeding, our baby gained over a pound!”
2. “I am a Pediatrician and used ByHeart with our first and am also using it with our second baby. I mainly use it to supplement but am happy that I am giving my baby clean and safe formula.”
3. “Our baby was sooo colicky for months, and this is the only formula that he has tolerated since we stopped breastfeeding. Can’t recommend enough—it’s been a lifesaver for us!”
4. “We have had no issues with this formula. Our baby transitioned from breast milk to this formula with ease, and the subscription option has been so helpful.”

 

 

Pros moms are sharing

1. Clean, organic ingredients with no toxic additives.
2. Gentle on stomachs and helps reduce colic and any digestive discomfort.
3. Supports healthy weight gain 
4. Easy transitions from breast milk.
5. Convenient subscription option.

3. The scoop holder in the can is finicky to use.

 

 

Subscription model explained 

I love having the option for a subscription for essentials you’ll be ordering on repeat, like diapers, and wipes.

The ByHeart subscription makes it easy to have formula delivered right to your door—no last-minute store runs or worrying about running out. They offer flexible quantity options (2 cans, 4 cans, 6 cans, or 8 cans) so you can choose based on how many feedings your baby needs each day.

It’s simple, reliable, and one less thing to think about. Plus, you can adjust the delivery frequency as your baby’s needs change, making it a hassle-free way to stay stocked up.

My take: Byheart infant formula review

ByHeart’s dedication to breast milk science and their commitment to safety and quality really make them stand out as one of the best formulas. From their trusted ingredients (and free from any additional ingredients) to owning every step of production here in the United States, it’s a big deal for parents navigating the first year of life. With clean-label certifications and added nutrients inspired by human milk, it’s clear why ByHeart is one of my top picks for families. They’ve thought about every detail—and as a mom, that matters.
