Soy Formula: The Best Dairy-Free Formula Alternative for Babies

For many parents, soy formula is the ultimate solution to gas, fussiness, and dairy-related allergies. Gentle on the stomach yet still nourishing enough to support healthy growth and development – there is a whole lot to love about soy formula! Should you make the switch to a soy-based formula? I’ll teach you everything you need to know about introducing soy formula to your baby’s diet.

Why use soy formula?

If for whatever reason you can’t give your baby breast milk or cow’s milk formula, soy is the next fallback. The American Academy of Pediatrics suggests the following as the only reasons you should choose soy formulas over cow’s milk-based formulas.

• Your baby is lactose or milk protein sensitive
• Your baby has a true milk allergy
• Your baby has congenital galactosemia
• You are raising your baby in a vegan or vegetarian family

If none of the above apply to your baby, then you have nothing to gain by swapping over to soy formula and should stick to breast milk or cow’s milk formula – As recommended by the AAP. But if it is necessary to use soy formula on your baby then there is nothing to worry about. Studies have shown that healthy babies grow just as well on soy as they do on cow’s milk formulas.

Pros and cons of soy formula

The thing to remember is that each baby responds to soy formula differently. There is no guarantee that your baby will experience the advantages or disadvantages listed below. As always, it is recommended that you consult your pediatrician before introducing new foods to your baby.

Pros

• It’s considered safe – A 2001 university study compared the difference in 811 adults – 248 who were fed soy formula with 563 who were fed cows milk formula as infants. No statistically significant differences were found across 30 outcomes in regards to general and reproductive health. The researchers concluded that the findings were reassuring in regards to the safety of infant soy formula.¹
• A great alternative to allergies – If your baby has a lactose intolerance, milk protein intolerance, or true milk allergy then a soy-based formula can provide an alternative.
• Relief from constipation – Many parents report that swapping over to reduced or eliminated constipation in their baby.
• Prevent reflux and gas – If your baby’s gas and reflux are linked to a dairy intolerance then swapping over to
• A plant-based formula option – While there are no 100% vegan baby formula options, soy formula is dairy-free, which means you can avoid supporting ethically dubious dairy industry.

Cons

• Soy allergies – It is not suitable for infants with a soy allergy.
• High in sugar – As I will discuss below, soy baby formula typically contains more sugar than cow’s milk formula.
• Can contain corn syrup – Check the ingredients! Some brands of soy formula use corn syrup as the sweetener, which is not suitable for babies with a corn allergy. Fortunately, there are many soy formulas available that use allergy-friendly sweeteners.

Despite the pros and cons, many healthy adults have been raised on it without any issues. If it works for your family then go for it!

The sweet side

If you currently have soy formula sitting in your pantry, take a look at the first ingredient. Chances are that it’s a sweetener.

Common sweeteners:

• Glucose Syrup
• Glucose Syrup
• Brown Rice Syrup
• checkCorn Maltodextrin

And they actually make up a large part of the overall formula. Check out the ingredients from Enfamil ProSobee Soy Formula. Are you shocked? I am. Over 50% of the formula is a sweetener. And Enfamil is actually one of the more honest soy formulas around because they actually state the percentage of the major ingredients!. Other brands of soy formula leave you guessing, but it’s highly likely the ratios are similar. Only a few soy formula brands chose to list the amount of sugar in each serving of formula. And it was a whopping 4g per serve. That’s a teaspoon of sugar in EACH baby meal. Now you may be asking yourself… Why all the sugar? It’s simple – Sweetener is added to improve the taste. Soy has a pungent and unusual flavor. Many adults find the taste disgusting. And your infant’s brand new taste buds would too. But if there is one thing that adults and babies both love, it’s sweet. So manufacturers of soy-based formula add a boatload of sweetener to reduce the chance of your baby rejecting the soy formula. There is no way around it. If you want to make the switch to a soy formula, you will have to come to peace with all

Best soy baby formulas

Below I will cover some of the best and most popular baby formulas on the market. Note: Just because one soy formula doesn’t work for your baby doesn’t mean that another will do the same.

A common misconception of soy formula

Soybean alone isn’t enough for your baby. While full of goodness, soybean cannot provide complete nutrition to your growing baby. As a result, soy formula will have additional ingredients added in order to provide a fully nourishing meal for your baby. These additional ingredients include essential fatty acids, carbohydrates, vitamins, and minerals. These are necessary for continued growth and development.

Soy formula and baby poop

Before I wrap up my guide on soy formula, I just wanted to quickly cover how it can affect your baby’s stool. Soy formula can cause constipation. But so can any other formula. It all depends on your baby. Some babies experience chronic constipation while others poop as normal. After making the switch to soy formula, you may notice that your baby’s poop is thicker and firmer. If so, you are not alone – many other parents have experienced the same.¹ To avoid constipation with soy formula, you are going to want to ensure that you are using the correct measurements. Using more than the recommended amount of soy formula is a good way to block your baby right up. The problem is, the instructions on the formula tin can be pretty vague. My interpretation of “One unpacked scoop” differs from my husband’s. The easiest way to ensure you are using the right amount is to pull out your kitchen scales and set it to grams. This will ensure you give your baby the perfect amount and minimize the chances of constipation.
