A Balanced Guide to Choosing Baby Formula

One thing we aren’t going to do is lose sleep over baby formula. There is no such thing as a perfect formula, because we don’t live in a perfect world. 

The reality is that infant formula is designed to nourish babies when breastfeeding is not possible or not preferred. Breastmilk is considered the biological standard, but formula exists to safely meet nutritional needs when needed. And what a wonderful thing that is!

Instead of chasing perfection, it’s more helpful to understand what ingredients are doing and decide what matters most to you. Give yourself permission and grace to make the best choice you can and let the rest go.

Whole Milk vs Nonfat Milk

Infant formulas can be made using either whole milk or nonfat (skim) milk with added fats. Both are carefully designed to meet an infant’s nutritional needs. The difference isn’t about one being more complete or better, but about how the fat portion of the formula is built.

With nonfat milk formulas, manufacturers start with a kind of “blank slate” when it comes to fats. Since the natural milk fat has been removed, they build the entire fat profile using a blend of oils. This allows for a high level of control over the types and amounts of fatty acids, and helps ensure consistency from batch to batch.

With whole milk formulas, manufacturers take a different approach. They start with natural milk fat already present, which includes a mix of fatty acids along with components like cholesterol and milk fat globule membrane (MFGM). From there, they add specific oils as needed to round out the fat profile and meet infant nutrition requirements. So while oils are still used, the formula is built on a foundation of milk fat + added oils, rather than oils alone.

There are reasons a manufacturer might choose either approach. Starting with a blank slate can offer flexibility in designing the fat profile, while starting with whole milk allows the formula to retain naturally occurring dairy fat components that some brands and families value.

Whole milk formulas may feel more “food-based” to some parents, while nonfat formulas offer a more fully customized fat blend. At the end of the day, it’s simply two different formulation strategies to achieve the same goal: providing the fats babies need for growth and development. Both are precisely formulated and regulated to support infants.

Organic vs. Grass-Fed vs. “Conventional”

The terms organic and grass-fed are often used together, but they refer to different aspects of how dairy is produced. Organic dairy is defined by farming practices. To be certified organic, cows must be fed organic (non-GMO) feed, synthetic pesticides and fertilizers are restricted, and antibiotics and growth hormones are not allowed. Organic standards also require cows to have access to pasture for at least 120 days per year, with a portion of their diet coming from grazing during that time. However, organic does not mean the cows are exclusively grass-fed.

Grass-fed, on the other hand, refers specifically to the cow’s diet. 100% grass-fed cows eat primarily grass and forage vs grain-based feed, which can lead to small differences in the milk’s fatty acid profile, like slightly higher omega-3 levels. However, grass-fed is not the same as organic. Unless a product is also certified organic, grass-fed cows may still be exposed to pesticides through their environment or feed, and antibiotic use may be permitted depending on the farming practices.

Conventional (non-organic, non–grass-fed) dairy comes from cows raised under standard agricultural practices, which often include grain-based feed and the use of conventional farming inputs. While sourcing and farming methods differ across all three, infant formulas (whether organic, grass-fed, or conventional) are all required to meet strict safety and nutritional standards, ensuring they provide complete nutrition for infants.

When choosing between these options, it often comes down to personal priorities and budget. Some parents choose organic to reduce pesticide exposure and avoid antibiotics, while others prefer grass-fed due to the cows’ forage-based diet and potential differences in fat composition. Some opt for both if available, while many choose conventional formulas because they are more affordable and accessible. Ultimately, these labels reflect differences in sourcing and philosophy, but they are not required for a formula to be safe or nutritionally complete.

Carbohydrates

Lactose is the primary carbohydrate in breastmilk. It’s made up of glucose and galactose and supports beneficial gut bacteria and calcium absorption.

For babies who tolerate lactose, formulas that use lactose as the main carbohydrate are closest to breastmilk. However, some babies cannot tolerate standard lactose levels. In those cases, formulas may use alternative carbohydrate sources.

This is where the confusion often happens.

High fructose corn syrup is NOT used in infant formula.

High fructose corn syrup is made up of a mix of glucose and fructose (typically around 55% fructose and 45% glucose), meaning more than half of it is fructose - a sugar that is not a primary component of breastmilk.

Infant formulas are designed to more closely reflect the carbohydrate profile of breastmilk. For that reason, high fructose corn syrup is NOT used in standard infant formulas.

I think what’s happening is people are confusing high fructose corn syrup and corn syrup solids/glucose syrup. They are NOT the same thing.

What some formulas do use instead are corn syrup solids or glucose syrup, which are made up of glucose (often in the form of glucose chains that are easily broken down in the body). Glucose is a simple sugar and the body’s primary fuel source.

These ingredients are used for specific functional reasons. In certain situations, like when lactose needs to be reduced or removed for lactose intolerances or conditions such as galactosemia where galactose cannot be properly metabolized, glucose-based carbohydrates like corn syrup solids are used because they provide readily usable energy without relying on lactose or fructose.

So while, yes, corn syrup solids may be more processed than lactose, they serve a targeted nutritional purpose and are not the same thing as high fructose corn syrup.

Seed Oils

This is one of the most misunderstood topics when it comes to baby formula. All infant formulas use a blend of fats, often including oils like sunflower, safflower, coconut, palm, or canola oil. Breastmilk naturally contains a complex mix of fatty acids, including palmitic acid, oleic acid, linoleic acid, and alpha-linolenic acid. Because no single fat source can replicate that profile, formulas use a combination of oils to more closely match the fats found in breastmilk.

They are not fillers. They are essential!

Without them, formulas would not be able to provide the fatty acids infants need. While the specific oil blends can vary between brands, the goal is the same: to deliver a nutritionally complete and balanced fat profile.

One ingredient that often raises concern is palm oil. Some parents choose to avoid it due to concerns about digestion or nutrient absorption. There is some evidence that certain forms of palm oil (specifically palm olein) can bind to calcium in the gut, which may lead to slightly firmer stools and, in some cases, reduced calcium absorption. 

To address this, some formulas use structured fats like beta-palmitate (also called high sn-2 palmitic acid), which more closely mimics how palmitic acid is positioned in breastmilk. This form is less likely to bind to calcium and may support softer stools and improved fat and calcium absorption. Because of this, some parents prefer formulas with beta-palmitate over those containing palm olein, but both types are considered safe and nutritionally adequate.

Goat Milk Formula

Goat milk formula can be a helpful option for some babies, particularly those who seem to struggle with standard cow’s milk formula. Compared to cow’s milk, it tends to form a softer, looser curd in the stomach, which may support easier digestion for some infants.

Goat milk also has a slightly different protein structure, with more A2-type casein and less A1 casein. Some families feel this is gentler on their baby’s digestive system, though tolerance can vary. It also naturally contains certain prebiotic oligosaccharides and minerals that are generally well absorbed.

Because of this, some babies may do better on goat milk formula for mild digestive discomfort like gas or fussiness.

However, goat milk is still a form of dairy and contains similar proteins and lactose, so it is not appropriate for babies with cow’s milk protein allergy or babies who require a lactose-free formula.

Lactose-Free Formula: Do You Really Need It?

True lactose intolerance in infants is extremely rare and is typically genetic. Babies with this condition usually show symptoms very early on, including poor growth and signs of malabsorption. More commonly, what parents may encounter is temporary or secondary lactose intolerance, which can occur after gut irritation or inflammation.

In these situations, lactose-free or reduced-lactose formulas can sometimes help improve symptoms. However, it’s important to understand that these formulas are not “lacking” carbohydrates, they simply use alternative sources (typically glucose-based), instead of lactose. These formulations are designed for specific circumstances where lactose isn’t well tolerated, rather than as a default or superior option.

Final Thoughts

At the end of the day, you have to do what you feel most comfortable with. Infant formula is highly researched and designed to safely nourish babies.

If formula is part of your journey, try not to lose sleep over choosing the “perfect” one. Choose what works best for your family, your baby, and your budget, and let that be enough.

Your energy is better spent bonding with your baby and showing up as a present. The internet can be loud, but it does NOT get to decide your worth as a parent!!
