Our Short Answer

Unfortunately, this is one of those comparisons where we can’t decide on a winning formula, as it will largely depend on your baby’s situation.

Choose Enfamil Gentlease if:

– Your baby has problems at the digestive level, either digesting cow’s milk protein, or lactose.

Choose Similac Pro-Advance if:

– Your baby has shown no signs of having digestive problems, or if they have, they can be considered minor or normal.


Whatever you do, you should always consult a pediatrician before making a decision, as the recommendation on the best formula may be more personal.

Overview of the Two Formulas

Enfamil Gentlease helps with digestive issues and contains DHA, ARA, corn syrup solids, and palm oil.

Similac Pro-Advance includes 2’-FL HMO, DHA, and lutein, and excludes palm olein oil for better calcium absorption.

Both formulas are free from artificial growth hormones and GMOs.

Enfamil Gentlease

Enfamil Gentlease is a well-known baby formula engineered with the comfort of babies as its primary concern.

The formula promises to help ease common digestive issues like gas, spit-up, and fussiness in just 24 hours.

It has DHA, ARA, corn syrup solids, palm oil and partially hydrolyzed protein.

Enfamil Gentlease doesn’t contain any artificial growth hormones, antibiotics, GMOs, or added table sugar.

Similac Pro-Advance

On the other hand, Similac Pro-Advance distinguishes itself with a unique ingredient: 2’-FL HMO, a prebiotic that strengthens the immune system to function similarly to that of a breastfed infant.

This infant formula also includes DHA and lutein elements often found in maternal milk, which support brain and eye development.

Similac Pro-Advance also excludes palm olein oil, known to hinder calcium absorption; hence it promotes excellent calcium absorption for strong bones.

Like Enfamil Gentlease, this formula contains no artificial growth hormones and is non-genetically modified.

Nutritional Composition

Enfamil Gentlease uses partially hydrolyzed proteins and corn syrup solids for carbohydrates, while Similac Pro-Advance has fully intact proteins and exclusively uses lactose.

Enfamil Gentlease contains palm olein in its fat content, while Similac Pro-Advance avoids it.

Both formulas include DHA and ARA for brain and eye development.

Protein Content

Enfamil Gentlease uses partially hydrolyzed nonfat milk and whey protein concentrate solids as its protein sources. The proteins are hydrolyzed, or broken down, making them easier to digest. This can be particularly helpful for babies with gas or general fussiness after meals.

Similac Pro-Advance consists of nonfat milk and whey protein concentrate. It contains fully intact proteins, which may be harder to digest than the partially hydrolyzed ones in Enfamil Gentlease.

Gentlease is designed for babies with tummy issues; that’s the reason why it uses partially hydrolyzed milk. It has a 60:40 whey-to-casein ratio, similar to breast milk.

Similac Pro-Advance, however, uses whey protein concentrate, a conventional source of protein for traditional formulas, designed for babies without digestive issues. Pro-Advance has a 48:52 whey-to-casein ratio, with more casein than whey.

Carbohydrate Content

Enfamil Gentlease primarily uses corn syrup solids as its chief source of carbohydrates. Corn syrup solids are often used in infant formulas because they are easy to digest.

Similac Pro-Advance uses lactose exclusively, derived from nonfat milk. Lactose is the carbohydrate found naturally in breast milk.

Again, very different approaches to carbs. 

Enfamil uses corn syrup solids instead of lactose since it is designed for babies with lactose intolerance.

Similac Pro-Advance uses only lactose, which is what we want to see in a conventional formula. 

Fats and Oils

Enfamil Gentlease contains vegetable oils such as palm olein, soy, coconut, high oleic sunflower oils, Mortierella Alpina Oil, and Schizochytrium Sp. Oil serve as the primary sources of fat.

Similac Pro-Advance relies on high oleic safflower oil, soy oil, coconut oil alongside sources of DHA and ARA (types of Omega-3 fatty acids) from Schizochytrium Sp. Oil and M. Alpina Oil, respectively, for its fat content.

Regarding fat content, Similac Pro-Advance has the advantage, just because it does not use palm olein (a more processed version of palm oil), and Enfamil does.

Both formulas also incorporate additional oils rich in specific fatty acids like DHA (Docosahexaenoic Acid) and ARA (Arachidonic Acid), crucial for brain development and eye health.

Probiotics and Prebiotics

Enfamil Gentlease does not include prebiotics or probiotics.

Similac Pro-Advance contains 2′-FL HMO, a prebiotic in breast milk, and fructooligosaccharides for immune support and promoting good bacteria growth.

Prebiotics and probiotics in infant formula are not essential ingredients, but they may prove really useful for some babies.

Enfamil Gentlease does not explicitly specify the inclusion of specific prebiotics or probiotics in its ingredient list but claims to have an exclusive blend that supports the immune system.

Similac Pro-Advance on the other hand contains 2′-FL HMO – a prebiotic found in breast milk known to foster good bacteria growth in the digestive tract, thereby boosting immunity. It also includes fructooligosaccharides as another prebiotic ingredient.
