Frequently Asked Questions

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

Yes, soy formula does taste 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’s 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 formulas for preemies generally, as soy formula might cause reduced bone mineralization in them.

Soy formulas are great alternatives to cow’s milk-based formulas if your child is lactose intolerant or your family is strictly vegetarian. They are made with natural ingredients and are free of added colors or flavors, and they help meet your child’s nutritional needs and are easy on your little one’s gut. When looking for the right soy formula for your baby, ensure it comprises nutrients that promote your child’s growth. Also, check with a pediatrician before adding soy formula or any new dietary supplement to your baby’s diet.
