Similarities Between Similac Sensitive and Pro Sensitive

Best for Sensitive Tummies

When it comes to suitability for infants with lactose sensitivity problems, Similac Sensitive and Pro Sensitive are beneficial. Infants showing fussiness and gas after feeding may get relief by switching to either of the two products.

Brain and Eye Development

Concerning boosting brain and eye development, the two infant formula milk register similar scores. The presence of DHA, vitamin E, and lutein play a vital role.

No Traces of Palm Olein Oil

Breastfed babies give out soft stools. Similarly, neither Similac sensitive nor Pro sensitive has palm olein oil. For that reason, they result in soft stools and efficient absorption of calcium nutrients.

As a result, your baby grows to have strong and healthy bones.

Not Fit for those with Galactosemia

Infants and children suffering from galactosemia shouldn’t take either Similac Sensitive or Pro Sensitive formula milk. Galactosemia is a health condition that makes the body inefficient in digesting galactose. Unfortunately, galactose is present in Similac sensitive, Pro Sensitive, and breast milk.

Differences Between Similac Sensitive and Pro Sensitive

Although Pro Sensitive Shares many similarities with Similac Sensitive, they have minor but tangible differences.


The Similac Pro Sensitive attracts a slightly higher price tag than the Similac Sensitive brand. Similac wins as the budget pick option. On the other hand, Pro sensitive counts as premium, high-quality formula milk with no GMO.

Presence of 2’-FL HMO

Only the Pro Sensitive formula has the 2’-FL HMO. It’s important to note that the human milk oligosaccharide helps in building a healthy immune system, gut health, and cognition.

Otherwise, the two share all other nutrients.

GMO Certified

Whereas the Pro sensitive has a certification to be free from GMOs, Similac sensitive has no such certification.

GMOs have attracted sharp reactions from people. Some people believe genetically modified organisms may cause adverse effects and diseases.

Product Recall

Similac Sensitive has suffered product recalls in the past on issues concerning contamination and manufacturing defects. However, the Pro Sensitive has a clear history with no product recall ever recorded.


It’s worth noting the preference for the taste of a particular product differs from one infant to the next. Hence it might not be obvious to know beforehand which of the two your infant may enjoy.

However past users point out that Similac Sensitive registers a strong taste that some infants object to. On the other hand, the majority of past reviews highlight that Pro sensitive has a rather sweeter taste. Consequently, your infant is more likely to enjoy it than the Similac sensitive.

But don’t forget that sometimes it’s hard to predict what babies might enjoy or hate.

Similac Sensitive vs Pro Sensitive: Which One Should You Choose?

Similac and Pro Sensitive have their good and bad sides. And knowing the ingredient composition, and the best and worst features of each infant formula milk helps in making an informed choice.

If you need a baby formula that’s affordable and fairly rich in nutritional value, then the Similac sensitive wins.

On the other hand, Pro Sensitive makes a better choice if you are looking for infant formula with;

  • No GMOs and artificial growth hormones
  • Rich in 2’-FL HMO for a better immune system

Otherwise, the two infant formulas share a good part of the ingredients in their composition.
