Best Organic Formula for Gassy Babies: What Actually Works
A gassy, colicky baby is one of the hardest things to navigate as a new parent. The crying, the discomfort, the helplessness of not knowing what is causing it — it exhausts everyone. And when formula seems to be making things worse, the pressure to find something better is real and urgent.
The good news is that formula-related gas and colic are often genuinely solvable problems. The right formula — one with the right protein structure, carbohydrate source, and without the additives that commonly cause digestive upset — can make a significant difference within days. European organic formulas, particularly from HiPP and Holle, are frequently recommended for sensitive babies precisely because their ingredient standards eliminate many of the culprits behind formula-related gas.
In this guide, we break down why formula causes gas, which ingredients to look for and avoid, and which specific European organic formulas work best for gassy or colicky babies — so you can make a confident choice without spending weeks trial-and-erroring through options.
Why Does Baby Formula Cause Gas?
Gas in formula-fed babies almost always comes down to one of three things: the protein, the carbohydrate, or an additive in the formula that the baby's immature digestive system cannot process efficiently. Understanding which of these is affecting your baby narrows down the solution considerably.
Protein Structure
Standard infant formula uses intact cow milk protein — whey and casein — which most babies handle well. But for babies with a developing or sensitive gut, intact protein can be harder to break down, leading to fermentation in the intestine and gas. Partially hydrolyzed formula uses protein that has been pre-broken into smaller fragments, which is significantly easier to digest. For babies with a more serious cow milk protein intolerance, fully hydrolyzed or hypoallergenic formula is used instead. Goat milk protein has a naturally smaller molecular structure than cow milk and a different casein composition, which many parents report causes less gas even without hydrolyzation.
Carbohydrate Sources
This is where US and European formulas diverge most significantly. Many US-produced formulas use corn syrup solids, glucose syrup, or maltodextrin as their primary carbohydrate — sweeteners that are rapidly fermented by gut bacteria and are a well-documented cause of gas and bloating in infants. European formulas, including all brands sold at Infantiz, are prohibited from using these sweeteners under EU food law. They use lactose as the primary carbohydrate — the same sugar found naturally in breast milk, which the majority of infants digest well. For babies with genuine lactose sensitivity, reduced-lactose options exist within the European formula range.
Additives and Fillers
Some US formulas contain carrageenan (a thickening agent), synthetic DHA/ARA from fermented fungal and algal sources with hexane residue, and various emulsifiers that can disrupt the gut microbiome. EU organic formula regulations prohibit carrageenan entirely and require stricter sourcing standards for all additives. If your baby is currently on a US formula and experiencing significant gas, simply switching to a clean European organic formula — even before trying a specialty comfort formula — often resolves the issue.
Ingredients That Make a Difference
When evaluating formula for a gassy baby, there are specific ingredients to look for and specific ones to avoid. This list applies whether you are reading a European label or a US one.
Look for:
Lactose as the first or only listed carbohydrate source. Partially hydrolyzed whey protein for sensitive babies. Added probiotics — particularly Lactobacillus strains — which support healthy gut flora and reduce gas over time. Prebiotics (galactooligosaccharides or GOS), which feed beneficial gut bacteria. A short, recognizable ingredient list without synthetic thickeners or emulsifiers.
Avoid:
Corn syrup solids or glucose syrup in any position on the ingredient list. Carrageenan. Soy-based formulas as a first response to gas — soy does not address cow milk protein sensitivity and introduces its own digestive challenges for many infants. Formulas where starch is listed early in the ingredients for a newborn, as starch thickeners can slow digestion and worsen bloating in very young babies.
Best Organic Formulas for Gassy Babies
1. HiPP Comfort — Best for Colic and Gas
HiPP Comfort is specifically formulated for babies with colic, gas, constipation, or general digestive discomfort. It uses partially hydrolyzed whey protein — pre-broken into smaller fragments that are significantly easier to digest than intact cow milk protein. The lactose content is reduced and partially replaced with a small amount of glucose syrup (the only HiPP formula where this appears, specifically because it causes less fermentation in sensitive babies than lactose alone). HiPP Comfort also contains the Combiotik probiotic and prebiotic blend. Most parents report noticeable improvement within 3–5 days of switching. It is available from birth with no stage progression — one formula covers the full period of discomfort.
2. HiPP Hypoallergenic (HA) — Best for Cow Milk Protein Sensitivity
If your baby's gas is accompanied by skin rashes, eczema, persistent mucus in stool, or significant bloating rather than simple wind, a cow milk protein allergy or intolerance may be the cause rather than standard digestive immaturity. HiPP HA uses extensively hydrolyzed protein, which breaks cow milk protein into fragments small enough that the immune system does not recognize them as a trigger. HiPP HA is available in PRE, Stage 1, and Stage 2 — covering birth through the end of the first year. It remains one of the most clinically referenced hypoallergenic formulas available from a European brand. Explore the full formula range to find the right HA stage.
3. Holle Goat Milk — Best for Cow Milk Sensitivity Without HA
For parents who want to move away from cow milk protein without using a hydrolyzed formula, goat milk is the most natural alternative. Holle Goat Milk formula uses certified organic goat milk with a protein composition that is structurally closer to human breast milk than standard cow milk — smaller fat globules, different casein ratio, and naturally lower levels of alpha-S1 casein, which is the most common trigger protein in cow milk intolerance. Holle Goat is available across Stages 1, 2, and 3, making it a viable full-term feeding solution. Many parents who switch from cow milk to Holle Goat report reduced gas within 48–72 hours.
4. HiPP Combiotik PRE — Best for General Gas in Newborns
If your baby is a newborn with gas but without signs of protein sensitivity or colic, HiPP PRE is an excellent first choice before moving to a specialty formula. It is starch-free, lactose-only, contains the full Combiotik probiotic and prebiotic blend, and is modeled as closely as possible on breast milk composition. The added probiotics begin supporting gut flora from the first feed, which often reduces gas and irregular bowel movements within the first two weeks. Browse PRE formula options to compare what is available.
5. Holle A2 Milk — Best for Mild Cow Milk Digestive Issues
A2 milk contains only A2 beta-casein protein, compared to standard cow milk which contains both A1 and A2. A1 beta-casein is digested differently and produces a peptide called BCM-7 during digestion, which some research links to digestive discomfort in sensitive individuals. Holle A2 formula uses certified organic A2 milk, making it a gentler option for babies who seem to struggle with standard cow milk formula but do not have a full intolerance. It is available in Stages 1, 2, and 3.

How to Switch Formula Without More Upset
Switching formula abruptly — even to a better one — can temporarily increase gas and fussiness as your baby's gut adjusts to a new protein and carbohydrate profile. A gradual transition over 5–7 days is almost always better tolerated than a cold switch, and it also helps you identify which formula is actually causing improvement.
Start by replacing one feed per day with the new formula for the first two days, then move to half-and-half for days three and four, then three-quarters new formula for days five and six, and full transition on day seven. If your baby shows significant distress at any point in the transition, pause and consult your pediatrician before continuing — particularly if you are transitioning to HiPP HA, where the change in protein structure is substantial.

Frequently Asked Questions
How quickly will a new formula reduce gas?
Most parents notice improvement within 3–5 days of fully transitioning to a new formula. For HiPP Comfort specifically, the partially hydrolyzed protein begins working from the first feed, but it takes a few days for the gut to fully adjust and for probiotic populations to begin shifting. If you see no improvement after 7–10 days on the new formula, a different formula or a consultation with your pediatrician is warranted — persistent severe gas may have a cause beyond formula composition.
Is goat milk formula safe for babies with a cow milk allergy?
Not necessarily. Goat milk and cow milk share a significant number of proteins, and most babies with a confirmed IgE-mediated cow milk protein allergy will also react to goat milk. Goat milk formula is better suited to babies with cow milk sensitivity or intolerance — where the digestive discomfort is not immune-mediated — rather than a true allergy. If your baby has been diagnosed with a cow milk protein allergy, HiPP HA is the appropriate choice, not goat milk formula.
Can I mix HiPP Comfort with regular HiPP formula?
Yes, mixing during a gradual transition is fine. However, mixing long-term is not recommended — HiPP Comfort is formulated as a complete system, and diluting it with a standard formula reduces the benefit of the partially hydrolyzed protein and the probiotic concentration. Use it as a full replacement once your baby is fully transitioned.
My baby was fine on formula for weeks, then suddenly became gassy. Should I switch?
Sudden onset gas in a previously settled baby is not always formula-related. Common causes include a growth spurt (which temporarily disrupts digestion), air swallowing due to a bottle teat that is too fast, or a developmental phase around 6–8 weeks when colic peaks regardless of feeding method. Before switching formula, try pacing feeding, burping more frequently mid-feed, and checking your bottle and teat size. If symptoms persist beyond 10 days or worsen, then revisiting formula is a reasonable next step.
Does HiPP Comfort have any downsides?
HiPP Comfort contains a small amount of glucose syrup to replace some of the lactose — this is intentional and clinically reasonable for a comfort formula, but it is worth knowing. It is the only HiPP formula where glucose syrup appears. Additionally, because it uses partially hydrolyzed protein, it has a slightly different taste than standard formula that some babies take a few feeds to accept. Most adapt quickly. It is not intended as a permanent formula — once your baby's digestion has settled, your pediatrician may recommend transitioning back to a standard stage formula.
Conclusion
Gas and colic are exhausting for both baby and parent — but they are rarely permanent and almost always responsive to the right formula choice. If you are currently using a US formula with corn syrup solids or glucose syrup as a primary ingredient, switching to any European organic formula is a sensible first step before trying specialty options. If your baby's gas persists or is accompanied by signs of protein sensitivity, HiPP Comfort or HiPP HA are the most targeted choices available in the European formula market. For babies where cow milk itself seems to be the issue, Holle Goat or Holle A2 are worth exploring.
