Quick Answer: Palm oil (or palm olein) is added to most infant formulas to mimic the palmitic acid in breast milk. While FDA-approved and safe, research shows it may reduce calcium absorption by 20-30% and contribute to constipation. This has led to increased demand for palm oil-free formulas like Kendamil, ByHeart, and Bobbie, which use alternative fat sources.
If you've been researching infant formulas, you've likely come across concerns about palm oil. This ingredient appears in the majority of formulas, yet many parents worry about its effects on digestion, calcium absorption, and stool consistency. Let me give you the complete picture so you can make an informed decision for your baby.
What Is Palm Oil and Why Is It in Formula?
Palm oil comes from the fruit of oil palm trees and is one of the most widely used vegetable oils in the world.
Types in Formula:
- Palm olein: The liquid fraction of palm oil (most common in formula)
- Palm oil: The full oil including solid fractions
- Sometimes listed as: "Palm olein," "palm oil," or hidden in "vegetable oil blend"
Why Formula Companies Use Palm Oil:
- Breast milk mimicry: Breast milk contains 20-25% palmitic acid
- Cost-effective: Palm oil is an inexpensive source of palmitic acid
- Fatty acid profile: Helps achieve the right balance of fats
- Widely available: Palm oil is abundant and stable
- Industry standard: Used for decades in infant formula
The breast milk connection: Breast milk naturally contains palmitic acid as about 20-25% of its fat content. Formula companies add palm oil as the easiest way to match this. However, there's a crucial difference in how it's structured, which is where the concerns come in.
What's the Problem with Palm Oil in Formula?
The Structural Difference
This is the key issue that causes all the concerns:
- In breast milk: Palmitic acid is in the "sn-2 position" (middle position on the triglyceride molecule)
- In palm oil: Palmitic acid is in the "sn-1 and sn-3 positions" (outer positions)
- Why it matters: The position affects how it's digested and absorbed
1. Calcium Absorption Issues
The most significant concern:
- Soap formation: Palm oil palmitic acid binds with calcium in the intestines, forming insoluble "soaps"
- Reduced absorption: Studies show 20-30% less calcium absorption with palm oil formulas
- Bone mineral content: Some research shows lower bone mineralization in babies fed palm oil formulas
- Fat loss: The calcium-palmitate soaps are excreted, meaning less fat absorbed too
2. Constipation and Stool Issues
Many parents report digestive problems:
- Harder stools: The calcium-palmitate soaps make stools firmer
- Constipation: More difficult and less frequent bowel movements
- Discomfort: Babies may strain or show signs of pain
- Less like breastfed stools: Stools are firmer and less frequent than breastfed babies
3. Lower Fat Absorption
- When fats bind with calcium, both are lost
- Reduces overall caloric absorption
- May affect fat-soluble vitamin absorption (A, D, E, K)
What Does Research Say About Palm Oil?
Key Research Findings:
- Calcium absorption (1999, 2006): Multiple studies show palm oil formulas result in 20-30% lower calcium and fat absorption
- Bone mineralization (2003): Infants on palm oil formulas had lower bone mineral content than those on palm oil-free formulas
- Stool consistency (2005): Firmer stools and more constipation reported with palm oil formulas
- Growth patterns (2007): Normal growth despite absorption differences (babies compensate by eating more)
- Long-term effects (2013): Most studies show children catch up in bone density later, though some questions remain
The Nuanced Reality:
- Not dangerous: Palm oil formulas are FDA-approved and millions of babies thrive on them
- Not optimal: Research clearly shows absorption disadvantages
- Individual variation: Some babies have no issues, others experience significant constipation
- Long-term unclear: Most concerning effects appear temporary, but long-term research is limited
Which Formulas Contain Palm Oil?
Most Major Formulas WITH Palm Oil:
- Similac: Most varieties including Pro-Advance, Sensitive, Total Comfort
- Enfamil: Most varieties including NeuroPro, Gentlease, Enspire
- Gerber: Most Good Start varieties
- Parent's Choice: Walmart brand formulas
- Up & Up: Target brand formulas
- Store brands: Most generic/store brands
- Many European brands: HiPP Germany, Aptamil, and others
How to Identify Palm Oil:
Check the ingredient list for:
- "Palm olein"
- "Palm oil"
- "Vegetable oil (palm oil)"
- Sometimes hidden in "vegetable oil blend"
Note: Palm oil is typically the first or second oil listed in the ingredient list, indicating it's a major fat source. Some formulas may contain small amounts for other purposes, but when it's a primary fat source, that's when concerns are most relevant.

Should You Avoid Palm Oil Formulas?
Consider Avoiding If:
- Baby has constipation: Frequent hard stools, straining, discomfort
- Calcium concerns: Family history of osteoporosis or bone issues
- Digestive problems: Ongoing tummy troubles
- Preference for optimal absorption: Want best possible nutrient uptake
- Budget allows: Can afford premium alternatives
Palm Oil Formulas Are Fine If:
- Baby thrives on current formula: Good weight gain, happy, normal stools
- No digestive issues: Regular soft bowel movements
- Limited options: Palm-free formulas not available or affordable
- Pediatrician recommends: Doctor is satisfied with growth and development
Important perspective: Millions of healthy babies have been raised on palm oil formulas. While palm oil-free may be optimal, palm oil formulas are not harmful or dangerous. Don't stress if palm-free isn't accessible or affordable for you.
Managing Palm Oil-Related Issues
If Your Baby Has Constipation on Palm Oil Formula:
1. Talk to Your Pediatrician
- Rule out other causes
- Get advice on formula switching
- Discuss safe remedies
2. Try These Strategies:
- Extra fluids: Offer water between feedings (for babies 6+ months)
- Tummy massage: Gentle circular motions on belly
- Leg cycling: Bicycle motion with baby's legs
- Warm bath: Can help relax muscles
- Prune juice: Small amounts for babies 4+ months (ask doctor)
3. Consider Formula Switch:
- Try a palm oil-free formula
- Or switch to a different brand (some babies tolerate certain palm oil formulas better)
- Give new formula 1-2 weeks before evaluating
Environmental Concerns About Palm Oil
Beyond infant health, many parents also consider environmental impacts:
Environmental Issues:
- Deforestation: Palm plantations have destroyed rainforests
- Habitat loss: Orangutans and other species threatened
- Carbon emissions: Forest clearing releases massive CO2
- Indigenous displacement: Communities affected by plantations
Sustainable Palm Oil:
- Some formulas use RSPO-certified sustainable palm oil
- Look for "sustainable palm oil" certification
- Still not perfect but better than conventional palm oil
- Enforcement and standards vary
The Ethical Dilemma:
For environmentally-conscious parents, this adds another reason to consider palm oil-free formulas, though the primary focus should remain on what's best for your baby's health.
Common Questions About Palm Oil in Formula
Is palm oil toxic or dangerous for babies?
No, palm oil is not toxic or dangerous. It's FDA-approved and used safely in millions of formula servings. The concerns are about suboptimal calcium absorption and digestive comfort, not toxicity or danger.
Will palm oil formula stunt my baby's bone growth?
No. While calcium absorption is reduced, babies fed palm oil formulas generally grow normally. Their bodies compensate, and most research shows any bone mineral differences resolve over time. Still, optimal absorption is preferable if possible.
Can I mix palm and palm-free formulas?
While not harmful, it defeats the purpose of avoiding palm oil and may confuse your baby's digestive system. If switching, do a gradual transition rather than mixing.
Do organic formulas have palm oil?
Many do! "Organic" refers to how ingredients are grown, not which ingredients are used. Check labels—many organic formulas contain organic palm oil. Bobbie is organic AND palm-free.
Why don't all companies remove palm oil if it's problematic?
Cost and formulation challenges. Palm oil is inexpensive and provides palmitic acid easily. Alternative fat blends are more expensive and technically challenging to formulate. As demand for palm-free grows, more companies may reformulate.
Transitioning from Palm Oil to Palm Oil-Free Formula
How to Switch:
- Day 1-2: 25% new formula, 75% old formula
- Day 3-4: 50% new formula, 50% old formula
- Day 5-6: 75% new formula, 25% old formula
- Day 7: 100% new formula
What to Watch For:
- Positive changes: Softer stools, easier bowel movements, less gas
- Adjustment period: Temporary changes in stool color/consistency are normal
- Watch for allergies: Rash, excessive fussiness, vomiting (rare but possible)
- Give it time: Allow 2 weeks to see full benefits
The Bottom Line on Palm Oil in Infant Formula
Key Takeaways:
- Palm oil is in most formulas to provide palmitic acid like breast milk, but the structure differs
- Research shows 20-30% reduced calcium absorption and firmer stools with palm oil
- Palm oil formulas are FDA-approved and safe, but not optimal
- Many babies do fine on palm oil formula with no issues
- Palm-free alternatives like Kendamil, ByHeart, and Bobbie offer better absorption
- Consider switching if baby has constipation or digestive issues
- Palm-free formulas are more expensive and less widely available
- Don't stress if palm oil formula is your only accessible option—it's still nutritionally complete
Palm oil in infant formula is a perfect example of why formula research and selection can be overwhelming. It's not black and white—palm oil is safe but not optimal, common but increasingly avoidable.
If your baby is thriving on a palm oil formula with no digestive issues, there's no urgent need to switch. If your baby has constipation or you can afford a palm-free alternative, it's worth considering. And if palm-free formulas aren't accessible or affordable, don't beat yourself up—focus on responsive feeding and overall care, which matter just as much as any single ingredient.
Remember: The best formula is one that your baby tolerates well, that you can afford consistently, and that supports healthy growth. Palm oil is just one factor among many. Always consult your pediatrician before making formula changes, especially if your baby has health concerns.
