⚠️ Safety update (July 2026): In November 2025 — after this comparison was researched — ByHeart voluntarily recalled ALL batches of its Whole Nutrition infant formula during an infant botulism outbreak investigation (28 confirmed cases; the CDC declared the outbreak over, but as of early 2026 the root-cause investigation was still ongoing). Check the FDA’s current guidance before buying or using any ByHeart product, and never use recalled cans. The comparison below is preserved for reference, but our verdict now favors Bobbie until ByHeart’s situation is fully resolved.
Bottom line up front, updated for the recall: the head-to-head below was researched before ByHeart’s November 2025 recall, and on pre-recall merits it was genuinely close. Today the safety update above outweighs the details — Bobbie is the one of the two we can currently recommend without an asterisk. The original comparison follows for context and for when ByHeart’s investigation fully closes.
I paid for every can, and affiliate links never change my verdicts. Here is how these two actually differ once the marketing is stripped away.
The quick comparison table
| Bobbie | ByHeart | |
|---|---|---|
| Recipe philosophy | EU-style, whey-dominant, minimalist | Additive — alpha-lactalbumin, lactoferrin, whole-milk base |
| Corn syrup solids | No | No |
| Mixing in my testing | Very clean, low foam | More foam, needs a swirl-and-rest |
| Where to buy | Primarily subscription/direct | Direct plus big-box retail |
| Rough prepared cost | around $0.24–$0.26/oz | around $0.22–$0.25/oz |
| Best for | Subscribe-and-forget families, gas-prone babies | Ingredient maximalists, store-tonight shoppers |
Prices shift with promotions and can sizes, so treat those figures as ranges and check the current listing.
Ingredient philosophy
Bobbie models itself on EU standards: whey-dominant, higher DHA than the US minimum, no corn syrup solids, and iron levels toward the FDA floor rather than the ceiling. It is deliberately minimalist — the pitch is “closer to European formula without the import headache.”
ByHeart takes the opposite approach — it adds. Its headline ingredients are alpha-lactalbumin and lactoferrin, two proteins found in breast milk that most US formulas skip. It also uses whole milk as a base, which changes the fat profile compared with the skim-milk-plus-oils construction most formulas use.
Backed by the research I could find, both philosophies are defensible. Neither uses ingredients I would flag on a label check, and both clear the bar I set in my ingredient-first reviews. If you enjoy that kind of label spelunking, my non-toxic baby shampoo guide explains the 30-second method I use on everything.
Mixing and daily-life tolerance
This is where daily life happens, and where a month with each formula taught me more than any label. Bobbie mixed cleaner for me — almost no clumping, minimal foam even when I was shaking bottles one-handed at 4 a.m. ByHeart foamed noticeably more and needed a swirl-and-rest to settle before feeding, which matters more than it sounds when the baby is already crying.
Tolerance-wise, my son had two slightly gassier days in the transition week onto ByHeart, then evened out completely. On Bobbie the transition was a non-event. Every baby is different here, and this is the one section where your results genuinely may not match mine — gut response is the least transferable data point in any formula review.
Price per prepared ounce
Running the numbers at standard dilution:
- Bobbie: roughly $0.24 to $0.26 per prepared ounce on subscription.
- ByHeart: roughly $0.22 to $0.25 per prepared ounce, and easier to catch on sale at big-box retail.
Call it a near-tie, with ByHeart slightly cheaper if you shop sales and Bobbie more predictable if you subscribe and forget. Over a typical formula-fed first year, the gap between them is small enough that I would not let price decide this matchup — pick on recipe and availability, then relax.
Availability, the underrated factor
Bobbie is built around its subscription, and it is the best-run formula subscription I have used — deliveries landed on schedule for a full month with zero intervention from me. ByHeart’s advantage is the opposite: when you misjudge your supply on a Sunday night, you can often grab a can at retail. If your household runs on autopilot, that difference matters more than any ingredient.
The verdict, by use-case
- You want an EU-style recipe without importing: Bobbie.
- You want the added breast-milk proteins: ByHeart.
- You need to grab a can at a store tonight: ByHeart, by availability.
- You want set-and-forget delivery that never runs dry: Bobbie’s subscription is the best I have used.
- Your baby is gas-prone: start with Bobbie’s whey-forward blend, and transition slowly no matter what you pick.
How to switch formulas without chaos
Whatever you choose, do a gradual seven-day transition: swap one feed the first two days, two feeds the next two, and so on. Judge nothing before day five — formula switches look worse than they are on day two, and most “this formula doesn’t agree with him” verdicts I hear from friends were issued 48 hours in. Keep bottle-feeding logistics simple too; my minimalist registry checklist covers why you should own four bottles of one brand instead of a sampler drawer.
FAQ
Is Bobbie or ByHeart closer to breast milk?
They chase that goal differently. ByHeart adds specific breast-milk proteins (alpha-lactalbumin and lactoferrin); Bobbie matches the overall whey-forward protein balance and EU-style nutrient targets. There is no regulator-approved scorecard for “closest to breast milk,” so be skeptical of anyone declaring a winner on that phrase alone.
Which formula is better for a gassy baby?
In my house, Bobbie’s whey-forward blend transitioned with zero drama, while ByHeart brought two mildly gassy days before settling. That is one baby’s data. The stronger lever is the transition speed: a slow seven-day switch prevents more gas than any brand choice.
Can I buy Bobbie or ByHeart in stores?
ByHeart is the easier one to find at big-box retail alongside its direct site. Bobbie is primarily subscription and online-first, with limited retail presence that changes over time — check current availability before you build your feeding plan around a store run.
How long does a can of formula actually last?
Depends entirely on age and appetite, but for a fully formula-fed baby in the middle months, most families burn through a standard can in roughly three to five days. Count your feeds per day before choosing a subscription cadence, and expect to adjust it twice in the first few months. Feeding patterns shift alongside sleep — my newborn sleep schedule guide shows how feeds and naps interlock in the early weeks.
Final word
You are choosing between two good options, which is a luxury worth naming. Pick by your baby’s gut and your buying habits, transition slowly, and spend the reclaimed decision energy on sleep — start with wake windows by age if you want the highest-leverage read.
