Best Formula For Constipation 2024: Review of Formulas that Help Relieve Constipation

Usually, babies that receive new formula tend to be more susceptible to constipation.

Telling if your child is truly a constipated baby can be tricky. But if you find that your little one is having trouble with bowel movements, you may wonder what is the best formula for constipation. Should you try Enfamil? Similac?

The best baby formula for constipation depends on a variety of factors, which we will discuss. However, there certainly are some formulas that can be better for constipation-prone babies. We will go into detail about our top picks of infant formula for constipation, including:

Formula and Infant Constipation

Baby formula is not as easily digested as breast milk. Therefore, formula fed babies can be more likely to be constipated. [1] Some formulas may be gentler on your baby’s system and reduce the chances of them becoming constipated.

However, it can be difficult to tell if your baby is actually constipated. One way to check is from your baby’s poop. Bowel movement patterns can vary from baby to baby and even week to week. Some infants regularly go poop each day while others can go a few days in between poops.

Constipation is a common condition in babies. Giving them baby formula designed to reduce constipation may help alleviate the condition.

What Are Some Signs of Constipation?

Look for these warning signs of constipation:

  • Difficulty passing stool
  • Not frequent bowel movements
  • Irregular straining during bowel movements.
  • Swollen belly
  • Cramps that are painful
  • Baby’s stool in the form of very hard pebbles or liquid stool that passes around blocked hard stool

You may need to watch your baby for a period of time to see if these symptoms are occurring regularly or if they are just having a flare-up of constipation. If it seems like they are suffering from chronic constipation, there may be a few different causes.

What Causes Constipation?

Common causes of constipation include:

  • Low fiber diet
  • Type of baby formula (extensively hydrolyzed vs. partially hydrolyzed )
  • Cow’s milk
  • Switching from breast milk to formula
  • Certain medications
  • Certain medical conditions

Babies with allergies or sensitivities are especially prone to constipation. If your child has an allergy to the protein in cow’s milk, they may suffer from gas, constipation, and painful digestion.

A baby with a dairy allergy will generally become constipated when ingesting baby formula that contains lactose. However, sometimes they can have the opposite issue, diarrhea. Another common allergy includes soy. A baby allergic to soy may experience digestive upset with a soy-based formula.

Switching from breast milk to formula can also lead to constipation. Breast milk is the most nutritionally sound and easily digested solid foods for a baby. Though baby formulas have come a long way, they are still not identical to breast milk. If you switch to formula your baby’s system may go through a brief period of shock in which constipation may occur.

How to Choose the Best Formula For Constipation

Does soy formula cause constipation? What about cow’s milk formulas? Truth is, the best formula to prevent constipation can vary from child to child. Let’s go through some of the criteria in choosing a suitable baby formula for your child.

Type and Form of Formula

There are many types of formula: cow’s milk protein, soy, hydrolyzed and partially hydrolyzed (where the proteins are broken down for digestion), amino fatty acids (often the most digestible and broken down), low-lactose, and lactose-free. It may take some trial and error to see which kind works best with your little’s tummy.

Types of Formula:

  • Cow’s Milk. Includes dairy milk proteins and is the most popular type. Usually the proteins are either partially or extensively broken down for digestive purposes.
  • Soy Formula. A plant-based option for babies who have a dairy allergy or sensitivity. Not a great option for babies with soy allergies.
  • Specialized Formula. There are various types. It can range from baby formula with added nutritional value for preemies or formula that is designed to alleviate colic.

Forms of Formula:

  • Powder. This is the most common form. It needs to be mixed with water and can be purchased in tubs or sticks.
  • Liquid Concentrate. This type needs to be mixed with water as well, but comes as a liquid and not a powder.
  • Ready-made. The baby formula and water come mixed and is ready to feed your child.

The more sophisticated or specific the formula composition, the more costly it is. Specialty formulas can cater to allergies, baby digestive issues, or even nutritional supplements. Generally, the most expensive formula costs around $30 a can. You should compare and contrast your budget with your child’s preferences and health needs.


Some formulas are more readily available than others. However, most can be purchased online. Whichever baby formula you choose, you will likely want to pick one that is easily accessible.

It is also helpful to know how long one can of formula can last. Formula is one thing your child cannot wait for if the store happens to be out or shipping is delayed.

Allergy Considerations

Wondering does milk make your babies constipated? Well in some children it can have this effect, especially for those with a lactose or dairy allergy. Other common allergies can include soy or gluten.

If your child has dietary restrictions be sure you choose a formula that will not cause them a reaction or lead to unpleasant symptoms.


Do you want baby formula with only organic formulas ingredients? Do you need a formula that avoids certain ingredients due to sensitivities or preferences? Be sure to thoroughly check the list of ingredients before committing to a certain type and brand.
