Similac Total Comfort vs Similac Sensitive

Similac creates some of the most popular baby formulas in the US, with all the nutrition your baby needs and no artificial growth hormones or unnecessary additives.

In this article, we will be covering all the differences between Similac Total Comfort vs Similac Sensitive formula to help you choose what will work best for your baby. 

Similac Total Comfort vs Similac Sensitive

You may be wondering what the difference is between Similac Sensitive and Total Comfort formula, with both of these being a popular option in a vast market of formula powders, it can be hard to know where to turn to make sure your little one is getting the best milk for them.

Both of these Similac formulas provide not only complete nutrition for your baby’s first 6 months of life, but they are also designed for infants who may suffer from an intolerance or sensitivity to lactose.

Let’s take a closer look at the signs to spot to see if your little one may have difficulty digesting lactose in their diet.

What is Lactose Sensitivity?

It is estimated in the US that over 30-50 million adults suffer from some variation of intolerance to lactose. Lactose is found in the sugar naturally found in dairy products such as yogurt, ice cream, cheese, and most baby formula on the market.

Lactose sensitivity means your body can’t digest the lactose, this will cause a range of symptoms from stomach cramps to diarrhea. Your baby can’t tell you when they’re feeling this way so it’s important to spot the signs and seek help and advice from your pediatrician or doctor to further diagnose the issues. 

The typical signs that your little one is suffering from an intolerance to lactose include:

  • Gas
  • Bloating
  • Diarrhea
  • Stomach pains

Spotting stomach pain in your little one can be commonly mistaken for typical behavior.

But if your little one is arching their back, getting very upset whilst passing gas, and generally seeming very tense and uncomfortable then your baby may be suffering from an intolerance to their current formula.

Cows Milk Allergy

You mustn’t confuse a lactose sensitivity or intolerance with an allergy to milk. The symptoms are similar, as well as some more concerning and serious side effects such as:

  • Wheezing
  • Coughing
  • Vomiting
  • Swelling

If you think your little one has a cow’s milk allergy it is important to seek medical confirmation from your pediatrician or doctor to help you test for your child allergens and know which formula will be best to direct you towards.

Similac also has a formula blend suitable for cow’s milk allergies called Alimentum. With an easy digest hypoallergenic formula it is designed without any lactose and contains broken down proteins to ease digestion in your little one.

Now we have covered the information you need to help you figure out if your little one has lactose intolerance or cows milk allergy, let’s take a look at the comparison between Similac Total Comfort and Similac Sensitive.

Similac Total Comfort 

This formula contains all the required vitamins and minerals for your little one in an easy-to-digest formula to ensure it doesn’t cause any issues on their delicate and sensitive tummy. 

In a study conducted by the brand, they found that parents reported a reduction in their child’s fussiness, gas, and crying after one day of switching to this formula.

This may be due to the inclusion of partially hydrolyzed whey protein that promotes easy digestion on your little one’s tummy. 

Whilst being gentle on your baby’s tummy, it also contains prebiotics commonly found in breastmilk as well as complete nutrition to strengthen their immune system alongside DHA and vitamin E to support their eyes and ever-learning brains.

Similac Sensitive

Unlike the pro-comfort formula, this blend doesn’t have whey protein meaning your little one may struggle to digest it as easily, but it is still suitable for lactose sensitivity in children.

It also features the same immune-supporting ingredients as the pro-comfort meaning your little one is getting all the vital vitamins they need to develop healthily.

Similac sensitive formula has an exclusive blend of ingredients they call OptiGRO containing DHA which is found in fish, Lutein found in spinach, and vitamin E which is found in breastmilk to support babies’ vital eye and brain development.

However, the Similac sensitive blend has a possibility of containing GMO’s meaning if this is something you are trying to avoid then you may want to opt for their Pro-Sensitive Formula which features all the same benefits as the original sensitive blend.


Now that we have covered the basics of both of these great formula options by Similac we can look further into the comparison between the two to help you decide.

Similac Total Comfort

  • Whey protein for easy digestion
  • Suitable for lactose sensitivity
  • Unique probiotics similar to breastmilk

Similac Sensitive has had a recent overhaul of their Pro-Sensitive blend which has all of the perks but without the GMO’s.

They have also included 2′-FL HMO which gives your little one better immune support as it is the third most abundant ingredient in breastmilk.

It has cognitive and memory benefits as well as immune response and promotes the growth of healthy bacteria your little one needs.

What Does Baby Formula Taste Like?

Looking at the comparison it is clear to see that Similacs Comfort formula has more benefits and a better variety of vitamins in comparison to their Sensitive blend.

If your little one is only suffering from lactose sensitivity then this blend will do the trick, but if they are also needing a gentle touch when it comes to digestion then you may just find Total Comfort will work better for your child.
