Choosing the right nutrition for a newborn is a decision that weighs heavily on every parent, especially when navigating the aisles of endless options. The primary concern is finding a blend that supports healthy growth, mimics the benefits of breast milk as closely as possible, and—most critically—does not cause digestive distress in a brand new, sensitive digestive system. Every ingredient, from the protein source to the fat blend, plays a direct role in your baby’s comfort and development.
I’m Min — the co-founder and writer behind Gadgets Feed. I’ve spent hundreds of hours analyzing the nutritional profiles, ingredient sourcing, and clinical research behind the top-selling infant formulas to determine which ones truly deliver on their promises for newborns.
After cross-referencing ingredient lists, customer feedback on digestive tolerance, and third-party certifications, this guide breaks down the best baby formula for newborn stages to help you confidently choose the right can for your baby’s specific needs.
How To Choose The Best Baby Formula For Newborn
Selecting an infant formula is not a one-size-fits-all decision. Newborns have immature digestive tracts, making the protein structure, fat sources, and the presence of prebiotics the most critical factors. You must first identify if your baby has a sensitivity to lactose or a true cow’s milk protein allergy (CMPA), as this dictates whether you should look at standard, gentle, or hypoallergenic options.
Protein Type: A2 vs. A1 Cow’s Milk
Standard cow’s milk formula contains a mix of A1 and A2 beta-casein proteins. Many parents report fewer digestive issues with formulas that exclusively use A2 milk, which is sourced from cows that naturally produce only the A2 protein. A2 protein’s structure is closer to the protein found in human breast milk, potentially leading to less gas and colic symptoms in sensitive newborns.
The Importance of DHA, ARA, and HMOs
DHA (docosahexaenoic acid) is an omega-3 fatty acid crucial for brain and eye development during the first year. Most premium formulas now include DHA at levels found in breast milk. Human Milk Oligosaccharides (HMOs) like 2′-FL HMO are prebiotics that nourish good gut bacteria and support the developing immune system. Look for formulas that explicitly list DHA, ARA, and specific HMO strains on the ingredient panel.
Digestive Comfort: Gentle vs. Hypoallergenic
A “Gentle” formula typically uses partially hydrolyzed proteins (broken down into smaller pieces) and a reduced lactose content to minimize gassiness and fussiness. A “Hypoallergenic” formula, like Similac Alimentum, uses extensively hydrolyzed proteins or amino acids for babies with diagnosed CMPA or severe colic. Do not use a hypoallergenic formula unless recommended by a pediatrician, as it is significantly more expensive and may lack some beneficial intact proteins.

In‑Depth Reviews
1. Enfamil NeuroPro Baby Formula
The Enfamil NeuroPro sits at the top of the premium tier for good reason—it features the Brain Building Duo of MFGM (milk fat globule membrane) components and expert-recommended DHA. This combination is clinically shown to support cognitive, motor, and communication development through age 5 when fed through the first year, a claim few competitors make. The 36.4-ounce tub offers solid value per ounce for a premium brand with this level of clinical backing.
Beyond brain development, Enfamil’s exclusive HuMO6 immune blend includes prebiotics designed to support the baby’s immune system. Parents with newborns who experienced reflux or gas often report that this formula is well-tolerated, mixing easily without clumps. The larger refill-pack format is particularly convenient for families who go through formula quickly, offering a better cost-per-feed than smaller containers.
Pediatrician recommendation data heavily favors Enfamil, making this a low-risk, high-trust choice for parents who prioritize research-backed nutrition. The primary trade-off is the cost—it is the most expensive standard cow’s milk formula in this lineup. For newborns who don’t have a cow’s milk protein allergy, this is the benchmark for complete nutrition.
Why it’s great
- Clinically proven MFGM for long-term cognitive benefits through age 5.
- Exclusive HuMO6 prebiotic blend supports a healthy immune system.
- Mixes easily with minimal clumping; available in a large 36.4-ounce tub.
Good to know
- Premium pricing—this is the most expensive standard formula in the guide.
- Not suitable for babies with cow’s milk protein sensitivity or diagnosed CMPA.
2. Happy Baby Organic A2 Stage 1 Baby Formula
Happy Baby Organic A2 is the only formula in this guide that holds both USDA and EU organic certification, and it is manufactured in Europe where ingredient standards are exceptionally high. The defining feature is its patented probiotic and prebiotic blend, clinically shown to bring a baby’s gut bacteria closer to that of a breastfed infant and to promote softer, more regular stools—a godsend for constipated newborns.
The A2 protein base makes this an excellent option for parents who suspect their baby has a mild sensitivity to the A1 protein found in standard formulas. Parents report significant improvements in eczema and reflux symptoms after switching to this formula, with some noting that it outperformed hypoallergenic alternatives in reducing spit-up frequency. The DHA6 blend matches levels found in breast milk for brain and eye development.
Availability can be an issue—Amazon listings occasionally go offline, requiring parents to source from Target or Kroger with longer delivery times. Once you find it, the 22.9-ounce can is competitively priced for a premium organic EU-made formula, but stock inconsistency is a real frustration for subscription-dependent families.
Why it’s great
- Dual USDA & EU organic certification—the highest standard in this guide.
- Clinically validated probiotic/prebiotic blend for softer, regular stools and gut health.
- A2 protein base is gentle on developing digestive systems and reduces reflux symptoms.
Good to know
- Stock is inconsistent on Amazon; may need to buy directly from the manufacturer or other retailers.
- Slightly higher cost per ounce than standard formulas like Similac or Enfamil.
3. Similac Alimentum Hypoallergenic Infant Formula
Similac Alimentum is the specialist in this lineup—it is not for everyday use but for babies with diagnosed cow’s milk protein allergy (CMPA) or severe colic stemming from protein sensitivity. The milk protein is extensively hydrolyzed, meaning it is broken down into tiny pieces that the immune system does not recognize as an allergen, virtually eliminating allergic reactions in sensitive infants. Most parents report seeing a reduction in colic symptoms within 24 to 48 hours.
What sets this apart from other hypoallergenic formulas is the inclusion of 2′-FL HMO, an immune-nourishing prebiotic also found in breast milk. This is the first and only hypoallergenic formula on the market to contain this specific HMO. The 19.8-ounce value can is the most cost-effective way to buy Alimentum, though it remains a premium-priced product compared to standard formulas.
The downside is the price—this is the most expensive formula per ounce in this guide, reflecting the specialized manufacturing process. Additionally, the extensively hydrolyzed protein gives the powder a distinct smell and taste that some babies need time to accept. This is a medical necessity product, not a casual upgrade, and should only be used under pediatrician guidance for confirmed protein sensitivity.
Why it’s great
- Extensively hydrolyzed protein virtually eliminates allergic reactions to cow’s milk.
- Contains 2′-FL HMO, an immune-nourishing prebiotic found in breast milk.
- Clinically proven to reduce colic symptoms due to protein sensitivity within 24 hours.
Good to know
- Highest cost per ounce—use only when medically necessary.
- Extensively hydrolyzed formula has a distinct smell and flavor some babies resist.
4. Baby’s Only A2 Organic Milk Infant Formula
Baby’s Only A2 Organic is a standout for parents who want the cleanest ingredient list possible. It excludes corn syrup, palm oil, GMOs, artificial colors, sweeteners, and growth hormones. Instead, it uses a proprietary organic fat blend of A2 organic milk and organic oils designed for easy digestion. The A2 beta-casein protein is structurally closer to breast milk, making this an excellent choice for newborns who exhibit gas or fussiness with standard A1-dominant formulas.
Manufactured in small batches in Ohio, the company emphasizes rigorous testing for purity and safety. Parents of low-birth-weight infants have reported that this formula supports healthy weight gain without causing digestive discomfort. The powder dissolves well with gentle shaking, and the 21-ounce can is priced competitively compared to other organic A2 options like Happy Baby.
One note: this formula does not include added probiotics or HMOs in the base recipe. Parents of cesarean-delivered babies, who often have different gut microbiomes, may need to supplement with an external probiotic to match the immune support found in formulas like Happy Baby. The absence of synthetic nutrients is a pro for purists but a potential gap for those seeking a complete immune package.
Why it’s great
- No corn syrup, palm oil, GMOs, or artificial growth hormones—extremely clean label.
- A2 beta-casein protein is gentle on sensitive newborn digestive systems.
- Made in small batches in the USA with rigorous safety testing.
Good to know
- Does not contain added probiotics or HMOs; C-section babies may need a separate probiotic.
- Limited stock issues on Amazon; can be harder to find than mainstream brands.
5. Similac Organic Infant Formula
Similac Organic brings the trust of the #1 infant formula brand fed in hospitals into the organic category. It is USDA-certified organic and made without artificial growth hormones, palm olein oil, and corn syrup. The formula is modeled after breast milk and includes a unique blend of DHA, lutein, and vitamin E—components also found in breast milk—to support brain and eye development during the critical first year.
This formula is an ideal entry point for parents who want organic without the premium price tag of smaller brands. At 20.6 ounces, it offers a strong value proposition for an organic product. Parents report that babies transition smoothly from breast milk or Similac Advance with minimal digestive upset, and the availability of a ready-to-feed liquid option makes late-night feedings or on-the-go use more convenient.
The main consideration here is that Similac Organic uses standard A1 cow’s milk protein. Newborns who are sensitive to A1 protein may still experience gas or fussiness, unlike with the A2-based options from Baby’s Only or Happy Baby. Additionally, while it is organic, it lacks the probiotic/prebiotic blend found in some competitor products—a gap that may matter for immune-focused parents.
Why it’s great
- USDA-certified organic with the trusted Similac brand backing.
- Contains DHA, lutein, and vitamin E for brain and eye development support.
- Available in ready-to-feed liquid format for convenience.
Good to know
- Uses standard A1 protein; may not be gentle enough for A1-sensitive newborns.
- Lacks added probiotics and prebiotics compared to newer organic competitors.
6. Mama Bear Gentle Premium Baby Formula Powder
Mama Bear Gentle is the budget-friendly champion of the gentle formula category. It is manufactured by Perrigo, the same company that produces most store-brand infant formulas in the US, and is designed to match the nutrition profile of Enfamil NeuroPro Gentlease. The key differentiator is the partially hydrolyzed protein, which breaks down the milk protein into smaller pieces, making it easier for newborns to digest and reducing fussiness, gas, and crying.
At 21.5 ounces for a mid-range price, this is one of the best values in the entire formula aisle. The container features a thoughtful scoop-holder design that keeps the scoop clean and accessible. Parents who transitioned from name-brand gentle formulas report that their babies accepted Mama Bear without fuss and experienced identical digestive outcomes—proof that you do not need to overspend for complete nutrition.
The trade-off is that like Enfamil Gentlease, this formula contains corn syrup solids and palm oil, which are common concerns for label-conscious parents. Some babies with extreme sensitivity may still experience constipation or spit-up due to the palm oil content. For the vast majority of newborns who simply need a less gas-inducing formula, this delivers exceptional results at a fraction of the cost.
Why it’s great
- Partially hydrolyzed protein significantly reduces gas, fussiness, and crying.
- Mid-range price provides the best value among gentle formulas.
- Container built with a convenient slot to hold the scoop.
Good to know
- Contains corn syrup solids and palm oil, which may concern label purists.
- Some extremely sensitive babies may still experience constipation from palm oil.
7. Bubs Essential Infant Formula
Bubs Essential is an Australian-made formula that punches well above its price tier. It is made with whole cow’s milk and includes prebiotics, probiotics, and plant-based DHA and ARA—a combination typically found in more expensive brands. The formula is Clean Label Project Award certified and meets the First 1,000 Day Promise standard, giving budget-conscious parents confidence that their baby is getting high-quality nutrition without the premium markup.
Parents who switched from Similac or Enfamil to Bubs report that their babies actually showed more enjoyment during feedings and had no issues with bowel movements or gas. The powder has a finer texture, which some may mistake for a thinner consistency, but it delivers the same essential macromineral and vitamin profile as more expensive options. The 20-ounce can is small, but the low price makes it easy to stock up without breaking the monthly budget.
The main limitation is that Bubs Essential uses standard A1 cow’s milk protein, not A2. For newborns with known A1 sensitivity, this may not provide the digestive comfort that A2-based formulas do. Additionally, the smaller can size means you will go through it faster—a minor inconvenience for the savings, but worth noting for families who want a larger tub to reduce packaging waste.
Why it’s great
- Prebiotics, probiotics, and plant-based DHA at a budget-friendly price point.
- Clean Label Project Award certified—tested for purity and contaminants.
- Made in Australia with whole milk; no GMOs, corn syrup, or artificial preservatives.
Good to know
- Uses standard A1 cow’s milk protein; not ideal for A1-sensitive newborns.
- Smaller 20-ounce can size means more frequent repurchases.
