Maltodextrin is a processed carbohydrate derived from starch — most commonly corn starch — that is used in some infant formulas as a carbohydrate source or thickener. It is not the same as corn syrup solids, but it is similarly derived from corn and raises similar questions for parents who want to understand exactly what their baby is consuming. In EU organic infant formula (Stage PRE and Stage 1), maltodextrin is not permitted as a primary carbohydrate — lactose is required. This guide explains what maltodextrin is, where it appears, and what the EU organic alternative looks like. For medical concerns or formula changes, always consult your pediatrician.
What Is Maltodextrin? A Plain-English Explanation
Maltodextrin is a polysaccharide — a chain of glucose molecules — produced by partially hydrolyzing (breaking down) starch, most commonly corn starch, though it can also be derived from wheat, potato, or rice starch. The result is a white powder that dissolves easily in water, has a mild or slightly sweet taste, and provides a readily available source of carbohydrate energy.
Maltodextrin has a high glycemic index — it is digested and absorbed quickly, raising blood glucose rapidly. It is used widely in processed foods, sports nutrition products, and infant formula as a carbohydrate source, thickener, or texture modifier.
Maltodextrin vs. Corn Syrup Solids: What's the Difference?
Parents often confuse maltodextrin with corn syrup solids. They are related but different:
- Corn syrup solids: Produced by hydrolyzing corn starch to a greater degree, resulting in a higher proportion of simple sugars (glucose). Higher sweetness, higher glycemic index.
- Maltodextrin: Produced by less complete hydrolysis, resulting in longer glucose chains. Less sweet than corn syrup solids, but still a high-glycemic carbohydrate.
- Lactose: The natural sugar in breast milk and cow milk. A disaccharide (glucose + galactose) with a lower glycemic index than maltodextrin or corn syrup solids. The primary carbohydrate in breast milk and required in EU infant formula.
Why Is Maltodextrin Used in Infant Formula?
Formula manufacturers use maltodextrin for several practical reasons:
- Cost: Corn-derived maltodextrin is significantly cheaper than lactose as a carbohydrate source.
- Solubility: Maltodextrin dissolves easily and mixes well, contributing to a smooth formula texture.
- Caloric density: It provides a concentrated source of carbohydrate energy, useful in formulas designed for higher caloric needs.
- Thickening: In anti-reflux formulas, maltodextrin or starch is used to thicken the formula and reduce spitting up.
- Reduced lactose formulations: In formulas designed for lactose sensitivity (such as comfort or gentle formulas), maltodextrin may partially replace lactose to reduce the total lactose load.
The Concerns Parents Have About Maltodextrin
Parents who research maltodextrin typically have several concerns:
High Glycemic Index
Maltodextrin has a glycemic index (GI) of approximately 85–105 — higher than table sugar (GI ~65) and significantly higher than lactose (GI ~46). This means it raises blood glucose more rapidly than lactose. For healthy infants, the clinical significance of this difference is not well-established — but parents who prefer a carbohydrate profile closer to breast milk (lactose-dominant) have a reasonable basis for that preference.
Derived from GMO Corn
The majority of corn grown globally is genetically modified. Maltodextrin derived from conventional corn is therefore likely to be GMO-derived unless the formula is certified organic or non-GMO. EU organic standards prohibit GMO ingredients, so any maltodextrin used in EU organic formula must be from non-GMO, organically grown starch sources.
Not Present in Breast Milk
Breast milk does not contain maltodextrin. Its primary carbohydrate is lactose, with human milk oligosaccharides (HMOs) as secondary carbohydrates. Parents who want a formula that most closely mirrors breast milk's carbohydrate profile prefer lactose-dominant formulas without maltodextrin.
Gut Microbiome Considerations
Some research suggests that maltodextrin may affect the gut microbiome differently than lactose — potentially altering the balance of gut bacteria. This research is primarily in adult populations and animal models; its relevance to infant formula feeding is not well-established. Lactose, by contrast, is a prebiotic substrate that supports the growth of beneficial gut bacteria in infants.

The Case For Maltodextrin: Where It Has a Role
A balanced guide should acknowledge where maltodextrin serves a legitimate purpose in infant formula:
- Comfort and gentle formulas: In formulas designed for babies with colic, gas, or digestive discomfort, reducing the lactose content (and partially replacing it with maltodextrin or starch) can reduce fermentation-related gas. HiPP Comfort, for example, uses a reduced-lactose formulation with modified starch.
- Anti-reflux formulas: Thickened formulas use starch (including corn starch or locust bean gum) to reduce spitting up. This is a clinically useful feature for babies with significant reflux.
- Caloric supplementation: In formulas for premature or low-birth-weight babies, higher caloric density may be needed — maltodextrin can contribute to this.
In these specific contexts, maltodextrin or starch serves a functional purpose. The concern is when it appears as a primary carbohydrate in standard infant formula as a cost-saving substitute for lactose.
Maltodextrin in EU Organic Formula vs. U.S. Conventional Formula
| Feature | EU Organic Infant Formula (Stage PRE/1) | EU Organic Follow-On (Stage 2) | U.S. Conventional Formula |

What to Check on a Formula Label
When reading a formula label for carbohydrate information:
Ingredient List
- First carbohydrate listed: In EU organic infant formula (Stage PRE and Stage 1), this should be lactose. If you see "maltodextrin," "corn syrup solids," "glucose syrup," or "corn maltodextrin" near the top of the ingredient list, it is not a lactose-primary EU organic formula.
- Starch in Stage 1: Some Stage 1 formulas include a small amount of starch alongside lactose — this is permitted in EU Stage 1 (but not Stage PRE). The starch should be a minor ingredient, not the primary carbohydrate.
- Maltodextrin in Stage 2: More common in follow-on formula (Stage 2) alongside lactose. This is appropriate for the weaning stage and is not the same concern as maltodextrin as a primary carbohydrate in infant formula.
Nutritional Panel
- Look for total carbohydrate content and, where listed, the breakdown between lactose and other carbohydrates.
- EU organic formula labels will typically state "of which lactose" in the carbohydrate breakdown.

When to Consult Your Pediatrician
Seek medical guidance before making formula changes if:
- Your baby has a diagnosed metabolic condition affecting carbohydrate metabolism (e.g., galactosaemia — these babies cannot tolerate lactose and require a specialized formula)
- You are considering switching from a reduced-lactose or lactose-free formula to a lactose-primary formula
- Your baby has persistent digestive symptoms that you suspect may be carbohydrate-related
- Your baby is premature or has a low birth weight — carbohydrate requirements may differ

Frequently Asked Questions
What is maltodextrin in baby formula?
Maltodextrin is a processed carbohydrate derived from starch (most commonly corn starch) that is used in some infant formulas as a carbohydrate source, thickener, or texture modifier. It has a high glycemic index, is not present in breast milk, and is often derived from GMO corn in conventional formulas. EU organic infant formula (Stage PRE and Stage 1) requires lactose as the primary carbohydrate — maltodextrin is not permitted as a primary carb.
Is maltodextrin safe in baby formula?
Regulatory bodies including the FDA and EFSA consider maltodextrin safe in infant formula within approved limits. It is a permitted ingredient in both U.S. and some EU formula formulations. The concern for parents is not safety in the acute sense, but whether it is the best carbohydrate choice for their baby compared to lactose — which more closely mirrors breast milk's carbohydrate profile and has a lower glycemic index.
Do European organic formulas contain maltodextrin?
EU organic infant formula (Stage PRE and Stage 1) requires lactose as the primary carbohydrate — maltodextrin is not permitted as a primary carb at these stages. Some Stage 1 formulas include a small amount of starch alongside lactose. Stage 2 (follow-on) formula may include more starch or maltodextrin alongside lactose, which is appropriate for the weaning stage. Stage PRE formulas (HiPP PRE, Holle PRE, Kendamil Stage 1) use lactose only.
What is the difference between maltodextrin and corn syrup solids in formula?
Both are derived from corn starch, but corn syrup solids are more completely hydrolyzed — resulting in a higher proportion of simple sugars, higher sweetness, and a higher glycemic index. Maltodextrin is less completely hydrolyzed, with longer glucose chains, less sweetness, but still a high glycemic index. Neither is present in EU organic infant formula (Stage PRE and Stage 1), where lactose is required as the primary carbohydrate.
Why do some formulas use maltodextrin instead of lactose?
Maltodextrin is significantly cheaper than lactose as a carbohydrate source, dissolves easily, and provides a concentrated source of carbohydrate energy. It is also used in reduced-lactose formulas (such as comfort or gentle formulas) to partially replace lactose and reduce fermentation-related gas. In standard infant formula, its use as a primary carbohydrate is primarily a cost consideration rather than a nutritional one.
Which EU organic formula has the least starch or maltodextrin?
Stage PRE formulas use lactose as the sole carbohydrate — no starch or maltodextrin. HiPP Combiotic PRE, Holle Cow PRE, and Kendamil UK Stage 1 are the closest to a pure lactose carbohydrate profile. If you want to minimize starch content, choose a Stage PRE formula rather than Stage 1. Always verify on the current product label, as formulations may be updated.
