Best Formula for Gas in 2026: A Parent's Complete Guide
If your baby is arching their back, pulling their legs to their chest, and crying after nearly every feeding, you are not alone. Gas discomfort is one of the most common concerns parents face in the first year of life, and choosing the best formula for gas can make a meaningful difference in how comfortable and settled your little one feels. This guide walks you through everything you need to know, from understanding why formula-fed babies experience gas to decoding ingredient labels, comparing formula types, and finding the right fit for your baby's unique digestive system.
Why Formula Can Cause Gas in Babies
Before we dive into which formulas are best for gas, it helps to understand what is actually happening in your baby's tiny digestive system. Newborns and young infants have immature guts. Their digestive enzymes are still developing, the microbiome in their intestines is being established, and the muscles that move food through the GI tract are not yet fully coordinated. This means that even under the best circumstances, gas is a normal and expected part of infant life.
According to the American Academy of Pediatrics, nearly all infants experience some degree of gas and fussiness in the first three to four months of life. Research published in pediatric journals in 2026 continues to confirm that gassiness peaks between weeks two and six, then gradually improves as the digestive system matures.
Formula can contribute to gas for several specific reasons:
- Protein structure: Standard cow's milk-based formulas contain large, intact proteins that some babies find harder to break down. When protein ferments in the gut before it is fully digested, gas is produced as a byproduct.
- Lactose content: Most standard formulas contain lactose as the primary carbohydrate. True lactose intolerance is rare in infants, but some babies do have temporary sensitivity that leads to extra gas and bloating.
- Iron content: Iron-fortified formulas are universally recommended for formula-fed infants, but some parents believe iron causes constipation and gas. Current evidence suggests iron at recommended levels does not significantly worsen GI symptoms, though individual responses vary.
- Air intake during feeding: The act of bottle feeding itself, if done with a fast-flow nipple or poor positioning, introduces extra air that must work its way through the digestive tract.
- Formula preparation: Shaking formula vigorously to mix it introduces bubbles. Allowing it to settle before feeding can reduce the amount of air your baby swallows.
Understanding the cause helps you choose the right solution. The best formula for gas addresses the specific digestive challenge your baby is experiencing, not just the symptom.

Reading a formula label can feel overwhelming, but there are specific ingredients that signal a formula is designed with sensitive digestive systems in mind. When you are searching for the best formula for gas, here is what to prioritize:
Partially or Extensively Hydrolyzed Protein
Hydrolyzed protein has been broken down into smaller fragments before it ever reaches your baby's gut. This pre-digestion process makes it significantly easier for immature digestive systems to handle. Partially hydrolyzed formulas are a good first step for mild gas and sensitivity, while extensively hydrolyzed formulas are typically recommended for babies with diagnosed milk protein allergies or more severe GI distress.
Reduced Lactose or Lactose-Free Options
Some sensitive-tummy formulas reduce the amount of lactose or replace it entirely with other carbohydrates like corn syrup solids or glucose polymers. If your baby seems particularly gassy after standard formula, a low-lactose option may provide relief. That said, lactose is actually beneficial for healthy gut bacteria, so removing it entirely is not always the best long-term choice unless there is a clear sensitivity.
Added Probiotics and Prebiotics
The infant gut microbiome plays a critical role in digestion and gas production. Formulas that include probiotics, particularly Lactobacillus reuteri or Bifidobacterium lactis, and prebiotics like galactooligosaccharides (GOS) and fructooligosaccharides (FOS) can help support a healthier gut environment. A 2026 review in the Journal of Pediatric Gastroenterology and Nutrition found that probiotic-supplemented formulas were associated with reduced crying time and improved stool frequency in infants with colic and gas.
DHA and ARA
While these fatty acids are primarily included for brain and eye development, they also support overall gut health and reduce inflammation in the GI tract. Their presence is a marker of a quality, comprehensive formula.
Gentle Iron Sources
All infant formulas sold in the United States must be iron-fortified per FDA guidelines. Some formulas use forms of iron that are slightly more bioavailable and may cause less GI irritation. Look for ferrous sulfate listed on the label, which is the standard and most researched form.
No Added Corn Syrup as the Primary Carbohydrate
Some formulas use added sugars like corn syrup solids as a primary sweetener. While not inherently harmful, these can contribute to gas and are worth noting if your baby's symptoms are not improving on a standard formula.
Types of Formula and How They Affect Digestion
Not all formulas are created equal when it comes to managing gas. Here is a breakdown of the main formula categories and how they typically impact digestion:
| Formula Type | Best For | Gas Relief Potential |
|---|---|---|
| Standard Cow's Milk-Based | Most healthy full-term infants | Low to moderate |
| Sensitive / Gentle Cow's Milk-Based | Mild gas, fussiness, and sensitive tummies | Moderate |
| Partially Hydrolyzed | Gas, colic, and mild protein sensitivity | Moderate to high |
| Extensively Hydrolyzed | Milk protein allergy, severe GI distress | High |
| Amino Acid-Based (Elemental) | Severe allergy, malabsorption conditions | Highest (for appropriate cases) |
| Soy-Based | Galactosemia, some lactose sensitivity | Variable |
| Goat's Milk-Based | Some babies who struggle with cow's milk proteins | Moderate |
It is important to note that soy formula is not typically recommended as a first choice for gas relief. Research shows that up to 50 percent of babies with cow's milk protein sensitivity are also sensitive to soy protein, meaning switching to soy may not resolve the issue and could introduce a new one.
Top Formula Options for Gassy Babies in 2026
Finding the best formula for gas often involves some trial and error, and that is completely normal. Pediatricians generally recommend giving a new formula at least one to two weeks before evaluating whether it is making a difference. Here is an overview of the formula categories that consistently receive positive feedback from parents and pediatric professionals for managing gas and digestive discomfort in 2026:
Gentle or Sensitive Cow's Milk-Based Formulas
These are the most logical first step for a baby experiencing mild to moderate gas on a standard formula. They typically feature partially hydrolyzed whey protein and reduced lactose, which together ease the digestive workload without moving to a fully therapeutic formula. They are widely available, more affordable than specialty options, and suitable for most babies without a diagnosed allergy.
Partially Hydrolyzed Formulas with Probiotics
This category has grown significantly in popularity and availability. The combination of pre-broken-down protein and added beneficial bacteria addresses gas from two angles simultaneously. These formulas tend to be well-tolerated and represent a meaningful step up from standard sensitive formulas without the cost or accessibility challenges of extensively hydrolyzed options.
Anti-Gas Comfort Formulas
Some formula brands specifically market products as anti-gas or comfort formulas. These often contain a blend of modified protein, lower lactose, and added prebiotics. They are designed to produce a softer stool and reduce the fermentation activity that leads to gas. Many parents find significant relief within the first week of switching to this type of formula.
European-Style Formulas
European formulas, particularly those from Germany and the Netherlands, have gained a loyal following in North America. Many parents find their babies digest these more easily, possibly due to differences in protein sourcing, carbohydrate types, and stricter standards around additives. They tend to be whey-forward rather than casein-forward, which is closer to the protein ratio found in human breast milk.
Goat's Milk-Based Formulas
Goat's milk protein forms a softer, looser curd in the stomach compared to cow's milk protein, which some parents and clinicians believe makes it easier to digest. While research is still emerging, a growing body of evidence in 2026 supports goat's milk formula as a viable option for babies with mild sensitivity to cow's milk proteins.

Even the best formula for gas cannot do all the work on its own. How you feed your baby matters just as much as what you feed them. Small adjustments to your feeding routine can dramatically reduce the amount of gas your baby takes in and help them move gas through their system more comfortably.
Choose the Right Nipple Flow
A nipple with too fast a flow causes babies to gulp air as they struggle to keep up with the milk. Start with the slowest flow available and only move up when your baby shows clear signs of frustration with the pace. Signs include excessive sucking effort, stopping frequently to breathe, or biting the nipple.
Hold the Bottle at the Right Angle
The bottle should be tilted at approximately 45 degrees so that the nipple is always filled with formula, not air. Feeding in a more upright position keeps the milk in front of any air bubbles rather than allowing your baby to swallow them directly.
Burp Frequently and Thoroughly
Rather than waiting until the end of a feeding, try burping your baby every one to two ounces. This breaks up the feeding into smaller segments and releases trapped air before it has a chance to travel further into the digestive tract. Experiment with different burping positions, including over your shoulder, face-down across your lap, and sitting upright with gentle back pats.
Let Mixed Formula Settle Before Feeding
If you prepare formula by shaking, let the bottle rest for a minute or two before offering it. The bubbles created by vigorous shaking are real and your baby will swallow them if the bottle is used immediately. Some parents prefer to stir formula rather than shake it to minimize bubble formation.
Try Paced Bottle Feeding
Paced bottle feeding is a technique where you hold the bottle horizontally, allow the baby to actively draw the milk rather than having it pour freely, and take regular breaks every few sucks. This mimics the effort of breastfeeding and significantly reduces air swallowing. Many lactation consultants and pediatric feeding specialists in 2026 recommend this technique as a standard practice for all bottle-fed infants.
Bicycle Legs and Tummy Massage
These are not formula-related but they belong in any gas guide. Gently moving your baby's legs in a cycling motion while they lie on their back can help move trapped gas through the intestines. A warm clockwise belly massage using two fingers follows the natural path of the large intestine and can encourage gas to move toward the exit.
When to Talk to Your Pediatrician
Gas is normal, but there are situations where it signals something that needs medical attention. Contact your pediatrician if your baby:
- Has blood or mucus in their stool
- Is not gaining weight appropriately
- Vomits forcefully or frequently after feedings
- Has a distended or visibly swollen abdomen
- Cries inconsolably for more than three hours a day, more than three days a week
- Shows signs of significant discomfort beyond what you would expect from typical gas
- Develops a rash, hives, or other allergic symptoms after formula changes
These symptoms can indicate conditions like gastroesophageal reflux disease (GERD), milk protein allergy, lactose intolerance, or other GI conditions that require proper diagnosis and treatment. Your pediatrician is your best partner in figuring out the right approach and can help you decide whether a specialty or prescription formula is appropriate for your baby.
It is also worth noting that switching formulas too frequently can make it harder to identify what is actually helping. Work with your doctor to create a plan and give each change enough time to evaluate its effectiveness before moving on.
A Note for Breastfeeding and Combination-Feeding Parents
If you are breastfeeding and supplementing with formula, or in the process of transitioning between the two, gas can temporarily increase during the adjustment period. This is normal and usually settles within one to two weeks as your baby's gut adapts to the new protein source.
For parents who are breastfeeding and noticing significant gas, it is worth knowing that maternal diet can influence the composition of breast milk. Dairy, soy, caffeine, and cruciferous vegetables are common culprits that some lactating parents find affect their baby's comfort. An elimination trial under the guidance of a registered dietitian or lactation consultant can help you identify whether diet adjustments might help.
If you are pumping and bottle feeding expressed breast milk, the same feeding technique advice applies. Paced bottle feeding, appropriate nipple flow, and regular burping are just as important with breast milk as with formula.
We at Moogco Baby understand that feeding your baby, whether at the breast, with a bottle, or a combination of both, comes with more questions than anyone prepares you for. Our products are designed to support you through every part of that journey.

Shop NowFrequently Asked Questions
What is the best formula for gas in newborns?
For newborns experiencing gas, a gentle or sensitive cow's milk-based formula with partially hydrolyzed protein is usually the recommended first step. These formulas are easier to digest than standard options and are appropriate for healthy full-term newborns. If gas is severe or accompanied by other symptoms like blood in stool or poor weight gain, consult your pediatrician before switching formulas, as a more therapeutic option may be needed.
How long does it take for a new formula to reduce gas?
Most pediatricians recommend giving a new formula at least one to two weeks before evaluating whether it is making a difference. During the transition period, gas may temporarily increase as your baby's digestive system adjusts to the new protein and carbohydrate sources. If symptoms worsen significantly or new symptoms appear, contact your pediatrician sooner rather than waiting out the full two weeks.
Is soy formula better for gas than cow's milk formula?
Not necessarily. Soy formula is not typically recommended as a first choice for managing gas. Research shows that up to 50 percent of babies who are sensitive to cow's milk proteins are also sensitive to soy protein. For most gassy babies, a gentle or partially hydrolyzed cow's milk-based formula is a more effective and evidence-supported choice. Soy formula is specifically recommended in cases of galactosemia or when parents prefer a plant-based option for non-medical reasons, and only after consulting with a pediatrician.
Can formula cause gas even if it says "gentle" on the label?
Yes. The term "gentle" is not strictly regulated, and different brands define it differently. Some gentle formulas feature reduced lactose, others feature partially hydrolyzed protein, and some feature both. Even a formula labeled gentle may still cause gas in a baby with a specific sensitivity. If a gentle formula is not providing relief after two weeks, discuss next steps with your pediatrician, who may recommend a partially or extensively hydrolyzed formula based on your baby's specific symptoms.
Does switching formula help with gas, or is it just a phase?
Both can be true at the same time. Many babies naturally outgrow significant gas and colic by three to four months of age as their digestive system matures. However, switching to a formula that is better suited to your baby's digestive needs can meaningfully reduce discomfort in the meantime. The best formula for gas is the one that addresses the specific reason your baby is struggling, whether that is protein structure, lactose levels, or gut microbiome support. A combination of the right formula and good feeding technique usually offers the most relief.
Final Thoughts: You Know Your Baby Best
Watching your baby struggle with gas is genuinely hard. The crying, the discomfort, the disrupted sleep, and the helpless feeling of not knowing what to do next, we understand why parents feel so anxious to find a solution. The good news is that gas in infancy, while uncomfortable and distressing, is almost always temporary and very manageable with the right approach.
Finding the best formula for gas may take a little patience and possibly a few tries. Start with a gentle or sensitive formula, pay close attention to your feeding technique, give each change enough time to work, and lean on your pediatrician as a partner throughout the process. You are not alone in this, and you are doing better than you think.
