Bottom line up front: both Bobbie and ByHeart are legitimately good formulas, and after feeding my son both for a month each, I could not crown one overall winner. The real answer is a verdict by use-case — Bobbie for EU-style minimalism and subscription reliability, ByHeart for its added breast-milk proteins and retail availability — and that is exactly what this comparison gives you.
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 |

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.
