7 Best Soy Formulas For Babies In 2024, Nutritionist-Reviewed

The best soy formula for babies may help tackle dairy-related allergies, fussiness, and gas in babies. Soy-based formulas are good alternatives to cow milk-based formulas if your baby is lactose intolerant. The American Academy of Pediatrics recommends choosing soy formula as it is safe and nutritious (1).

I took the help of Jenni Hackworth, a nutritionist, yoga trainer, and mom, to choose the best soy formulas for your little one. She says, “If you and your spouse are strictly vegetarian or your child is intolerant to lactose, you may consider soy formula over cow-milk-based formula. However, consult a nutritionist or pediatrician to ensure soy formula is safe and a good option for your baby.”

Read this post as I share some safe and healthy soy formulas specially formulated to help treat your child’s digestion-related issues or meet their nutritional needs.

How To Choose The Right Baby Soy Formulas?

Here are a few essential factors to keep in mind while choosing a baby soy formula.

  1. Organic: Choose organic formulas that have no pesticides, genetically engineered components, and growth hormones.
  2. Ingredient: Check the ingredient list to ensure it is easily digestible and a good alternative to dairy products for babies prone to allergies. Consider safety-tested formulas with prebiotics, probiotics, and no preservatives for optimal digestive health.

  4. Development: Ensure the formula is pediatrician-recommended and has expert-approved DHA and other nutrients to promote your child’s eye and brain growth.

Frequently Asked Questions

1. Do soy formulas taste different from milk-based formulas?

Yes, soy formula tastes different as its flavor is determined by the base, minerals, vitamins, and sweetener utilized.

2. Will soy formula cause constipation in my baby?

Some soy and cow milk-based formulas generate firmer bowel movements. However, formulas with partially or completely hydrolyzed milk proteins (often known as “hypoallergenic” formulas), which may be suggested for infants with a cow’s milk allergy or sensitivity, may cause loose bowel movements.

3. Can I use soy formula for a preemie?

Pediatricians do not recommend soy formula for preemies, as it might cause reduced bone mineralization in them.

4. Is soy formula good for babies?

Doctors recommend soy formula if parents do not want babies to ingest animal-based protein or if their baby is lactose-intolerant (1). However, some infants may be sensitive to estrogen-like compounds in soy (2). Speak to your doctor before giving soy formula to your baby.

5. Does soy milk make babies poop more?

Yes, to some extent. Infants who consume soy formula have increased bowel movements than infants who drink cow milk.

6. How do you know if the formula isn’t agreeing with the baby?

Whether it is a plant-based formula or cow milk-based formula, your infant would show some signs if they are formula intolerant. Vomit, diarrhea, and fussiness are some common symptoms (1).

7. Will soy formula help with reflux?

Do not offer any soy formula to your baby if they have reflux. Speak to a pediatrician, and they would recommend anti-reflux formulas for your baby (3).
