Selecting a first milk powder for a newborn is one of the most researched decisions a parent makes. The aisle is crowded with claims about organic ingredients, special proteins, and digestive support, but the real question is always the same: which formula will your baby actually tolerate and thrive on without excessive gas, reflux, or fussiness?
I’m Mohammad — the founder and writer behind ProteinJug. I analyze nutritional labels, manufacturing standards, and real-world feeding data from thousands of verified buyer experiences to help parents make informed choices about infant nutrition.
After sorting through the top contenders by ingredient quality, digestive gentleness, and third-party certifications, I’ve put together a focused list of the best milk powder for newborns that balances safety, nutrition, and value for your little one.
How To Choose The Best Milk Powder For Newborns
Newborn digestive systems are immature and sensitive. The wrong formula can lead to excessive gas, spit-up, and colic-like crying. Understanding a few key differences between formulas will help you pick one that agrees with your baby’s stomach from the first bottle.
Protein Type: A2 vs. Standard A1 Casein
Standard cow’s milk contains a mix of A1 and A2 beta-casein proteins. Some research suggests A1 protein can be harder to digest and may contribute to inflammation and digestive discomfort in sensitive infants. Formulas made with A2 milk, like Baby’s Only A2 Organic and Happy Baby Organics Stage 1, source milk from cows that produce only A2 beta-casein, which is the same type of casein found in human breast milk. This can reduce gas and fussiness in newborns with sensitive tummies.
HMO Prebiotics for Immune Support
Human Milk Oligosaccharides (HMOs) are the third most abundant solid component in breast milk and serve as food for beneficial gut bacteria. Formulas enhanced with HMOs like 2′-FL and LNnT help establish a healthy gut microbiome and support immune system development. The Mama Bear Advantage Premium includes dual HMOs, while Happy Baby Organics adds both prebiotics and probiotics for a synergistic digestive benefit.
Partially Hydrolyzed Whey for Gas and Fussiness
Some newborns struggle with standard intact milk proteins, which can be harder to break down. Partially hydrolyzed whey protein is broken into smaller pieces during manufacturing, making it easier to digest. The Mama Bear Gentle Premium formula uses this approach, along with reduced lactose content, to minimize crying, gas, and general fussiness. This is a good option if your baby shows signs of formula intolerance without a true milk allergy.

In‑Depth Reviews
1. Bubs Essential Infant Formula
Bubs Essential covers the essentials without overcomplication. Made in Australia from whole cow’s milk, this formula includes both prebiotics and probiotics alongside plant-based DHA and ARA for brain and eye development. The Complete Nutrition 0-12 month profile means one can carries you from the newborn stage through the first birthday, reducing the need to switch formulas later.
The Clean Label Project Award and First 1,000 Day Promise certification speak to the purity of the ingredients. No GMOs, corn syrup, artificial colors, or preservatives. Multiple verified reviews note that babies with food allergies and sensitive stomachs tolerated this formula well, with regular bowel movements and no excessive gas. The mixing ratio is straightforward at one scoop per two ounces of water.
At this tier, Bubs delivers a premium ingredient list without a premium price tag. The 20-ounce can size is practical for testing a new formula before committing to larger containers. For parents who want clean Australian-sourced nutrition with digestive support built in, this is the safest starting point.
Why it’s great
- Includes both prebiotics and probiotics for gut health
- Clean Label Project Award certified
- Australian-made with no corn syrup or GMOs
- Works well alongside breastfeeding
Good to know
- 20-ounce can may not last as long as larger containers
- Not fully organic like some competitors
2. Baby’s Only A2 Organic Milk Infant Formula
Baby’s Only is built around a single insight: A2 beta-casein protein, the same type found in breast milk, is naturally easier for newborns to digest than standard A1 protein. This organic formula sources milk exclusively from cows that produce only A2 protein, and it avoids palm oil, corn syrup, and artificial growth hormones entirely. The proprietary organic fat blend uses organic oils that mimic the fat profile of breast milk.
Manufactured in small batches in Ohio, this formula is USDA Organic and has earned strong reviews from parents of low birth weight infants and babies who reacted poorly to other formulas. Verified buyers report zero gas issues, normal bowel movements, and excellent growth tracking. Several parents noted it served as a smooth transition from breast to bottle, with babies accepting the taste without fuss.
The 21-ounce can size is slightly smaller than some competitors, but the concentrated ingredient quality justifies the trade-off. For parents specifically seeking an organic A2 formula that prioritizes digestive gentleness for newborns, this is a top-tier option. The main downside is intermittent stock availability, so subscribing is advisable.
Why it’s great
- USDA Organic with A2 beta-casein protein for easier digestion
- No palm oil, corn syrup, or artificial growth hormones
- Made in small batches in a U.S. facility
- Excellent for low birth weight infants
Good to know
- Stock can be inconsistent on Amazon
- 21-ounce can is relatively small per feeding
3. Mama Bear Advantage Premium Baby Formula
Mama Bear Advantage Premium delivers dual HMO prebiotics (2′-FL and LNnT) at a price point that undercuts most name-brand equivalents. These HMOs are the same prebiotics found in breast milk and support the growth of beneficial bacteria in the digestive tract, which directly supports immune system development. The formula also includes DHA, Lutein, Vitamin E, and Choline for brain and eye development.
Amazon’s house brand meets the same FDA nutritional and quality standards as national brands, and it is SNAP eligible. Verified reviews consistently highlight the value proposition — parents report seamless transitions from Similac and Enfamil with no noticeable difference in their baby’s tolerance or satisfaction. The 34-ounce can is one of the largest in this comparison, reducing the frequency of repurchasing.
For budget-conscious parents who want HMO-enhanced nutrition without paying a premium, this is the most logical choice. The formula avoids palm olein oil, artificial growth hormones, and GMOs. The only trade-off is that it is primarily available through Amazon, so you cannot run to a local store if you run out.
Why it’s great
- Dual HMO prebiotics at a budget-friendly price
- Large 34-ounce can lasts longer between purchases
- Non-GMO with no palm olein oil
- Comparable nutrition to major national brands
Good to know
- Exclusive to Amazon — not sold in retail stores
- Not certified organic
4. Happy Baby Organics Stage 1 A2 Infant Formula
Happy Baby Organics is the only formula in this comparison that holds both USDA Organic and EU Organic certifications while being made in Europe. It is also the first to tailor key nutrient levels across different stages — Stage 1 for newborns differs from Stage 2 for older infants. The formula uses A2 milk and adds a patented blend of prebiotics and probiotics that is clinically shown to support softer, more regular stools and bring gut bacteria closer to that of breastfed infants.
Verified parents report this formula significantly improved reflux symptoms in newborns who did not tolerate hypoallergenic formulas. Others noted that it tastes less sweet than standard formulas, which made it easy for babies to accept after breastfeeding. The Clean Label Project Certification adds another layer of purity assurance. The 22.9-ounce can is European-sized and slightly smaller than U.S. standard cans.
If your newborn struggles with reflux or you want the highest organic certification standards combined with A2 milk and active probiotics, this is the formula to try. Availability can be spotty on Amazon, and some parents recommend ordering directly from the manufacturer’s auto-ship program to avoid shipping errors.
Why it’s great
- Dual USDA and EU Organic certification
- Patented prebiotic+probiotic blend for softer stools
- A2 milk with stage-specific nutrient levels
- Clinically shown to reduce reflux symptoms
Good to know
- Amazon shipping can be unreliable for this item
- Not eligible for WIC or EBT benefits
5. Mama Bear Gentle Premium Baby Formula
Mama Bear Gentle Premium is designed specifically for newborns who struggle with gas, crying, and general fussiness after feeding. The key differentiator is partially hydrolyzed whey protein, which is broken into smaller peptides for easier digestion, combined with reduced lactose content — only 20 percent of the lactose found in standard full-lactose formulas. This makes it a direct alternative to Enfamil Neuropro Gentlease at a more accessible price point.
The formula also includes 2′-FL HMO for immune support, DHA for brain development, and a non-GMO ingredient list with no artificial growth hormones. Verified reviews are overwhelmingly positive, with parents reporting smooth transitions from Similac and Enfamil with no digestive upset. Multiple reviewers noted the formula mixes easily without clumps and that the can design includes a dedicated spot to store the scoop.
The 33.2-ounce can is one of the largest in this group, and the consistent quality across subscription deliveries makes it a practical choice for long-term use. For parents whose newborn shows signs of lactose sensitivity or general formula intolerance, this gentle option is worth moving up the list.
Why it’s great
- Partially hydrolyzed whey for easier digestion
- Reduced lactose for gassy, fussy newborns
- Large 33.2-ounce can with smart scoop storage
- Comparable to Enfamil Gentlease at lower cost
Good to know
- Shipping may be slower without Prime membership
- Not available in physical retail stores
