When a baby has a problem that prevents them from ingesting standard formula, then they require a special formula like Similac Sensitive. If your infant is healthy, you can give him or her a nourishing solution like Similac Advance.

Similac comes from one of the companies you can trust if you are seeking the ideal nutrition for your child. Similac is a baby formula corporation that has been around for over 100 years.

Their product formulations are known for their exceptional quality. In addition, as a result of their dedication to their brand, we now have a variety of Similac formulations to choose from.



Here, we are about to discuss the highlights of Similac sensitive and Similac advance to help you choose the best between them.

Similac Advance Review

Similac Advance is chock-full of essential nutrients that will help your baby grow and flourish. This includes Lutein, which aids in the development of healthy and active eyes, as well as Vitamin E, which is an important component of your toddler’s overall health. 2′-FL Human Milk Oligosaccharide is included as well. You may not be familiar with this protein, but it is still a prebiotic that boosts immunity to its peak and is generally found in breast milk.


 Similac says that it is validated by many more than 15 years of intensive study and provides an extra element of immune support to Similac’s already established formula. Similac is no 1 formula chosen by the majority of mothers out there.


Synthetic estrogens are not present in Similac Advance or any of their other formulas. This indicates the dairy components which are from livestock that haven’t been given hormones to help them develop faster. This is something that many parents desire.


Another excellent feature of Similac Advance is that it can be purchased at several pharmacy shops and supermarkets. If your baby ends the old jar at night, you can find a new one as soon as the markets open at your nearest pharmacy or supermarket.

  • A complete healthy formula that provides all the necessary nutrients, which are required by a 6-12 months old baby for healthy growth.
  • Comes in a stainless steel jar, with a net weight of 12.4 OZ (352 gm)
  • Trusted brand certified by many health professionals and authorities. Mom’s no. 1 choice.
  • Almost equal to breast milk in terms of health benefits and nutrients.
  • Similac Advance, like any other infant formula, may take some time to get up to.
  • It is also very pricey in comparison to other manufacturers, which is something to keep in mind if you are looking for something long-term.
  • It is also not the ideal option for infants because it lacks some of the crucial nutrients they will require. This formula is best for babies who are 6 to 12 months old.
  • Similac advance 2 can be a better option in some cases.


Similac Advance is a formula that provides a lot of minerals to newborns that handle lactose well. The latest product of this mixture contains more Iron than the Sensitive variant. If your child has an irons deficit, then this is one of the finest daily formulations you can feed them.

This recipe also provides many of the other ingredients contained in Similac Sensitive, but it is somewhat more saturated. If your infant is experiencing any medical problems, an enriched formula like Similac Advance may be able to help them build strength and boost their immune function more quickly than other formulations on the market.

Even though this is not an allergenic diet, giving that to your newborn daily will not put him or her at risk. Similac Advance’s components are of the highest quality, and you may find it beneficial to use them during your newborn’s first year!

Similac Sensitive Review

Similac Sensitive is made for babies with sensitive stomachs, crankiness, or gas problems due to lactose sensitivity. Lactose has been eliminated from the feed since it uses milk protein concentrate rather than milk. This makes it safe for newborns who have an allergy, including cow’s milk.


Similac Sensitive contains vitamin E and lutein, same as Similac Advance. This is to guarantee that newborns grow up to be robust. 2′-FL Human Milk Oligosaccharide is also present. Overall, Similac Sensitive is made to flavor and feel like breastfeeding, ensuring that your baby gets all that needed in a strong upbringing without sacrificing the quality of the meal.


Similac Sensitive includes iron as well. This is a crucial component in preventing anemia in young babies during their first year. You may buy the mixture in powdery or fully prepared form, depending on your preference. The latter would be particularly useful when you’re on the run and need something quick to grasp throughout a hectic time of day.

  • Contains Human Milk Oligosaccharide which is a known nutrient to boost immunity in newborns and make them stronger
  • Contains DHA, for the brain nourishment and growth of the baby.
  • Comes in a net weight of 34.9 OZ (989) grams.
  • Features OptiGRO and an exclusive mix of DHA, Lutein, and Vitamin E, which are vital nutrients present in mother’s milk for supporting a baby’s brain and vision development.
  • Has no artificial growth hormones.
  • Similac Sensitive has indeed been linked to the occurrence of diarrhea in certain babies. That is an uncommon occurrence, but it is dependent on your infant’s immunity.
  • It is cheaper than Similac advanced but still considered a bit pricy
  • It does not contain any probiotics
  • It can cause constipation in some cases
  • The taste of this formula is strong, it might not match with the taste buds of your baby.


Similac Sensitive is for your infant if he or she is allergic to milk. Because this formula is made with milk, it will not help people with lactose intolerance. However, it will minimize diarrhea and fussiness, which are frequent milk allergy symptoms.

If your child has lactose intolerance, you should feed them an organic formula that is pure of dairy components. Your physician will provide you a small list of suggestions, so do not make this choice on your own.

Similac Sensitive ensures that your child receives all of the nutrition they require without experiencing lactose intolerance effects. Unless your physician advises differently, you will not need to add any additional vitamins to their food. This formula also contains Iron, however, it is not Iron enriched.


As we have already discussed that both of these products are a go-to option for your baby. The main difference between the usage of both these products is whether your baby can bear lactose or not. It does not matter which formula you choose from the above-mentioned ones, Trust me you will not be disappointed at all.

However, as a matter of fact, you should be aware of their similarities so you can differentiate them even better and choose the formula according to the needs of your baby.

Both of the products are for newborn babies 1-year-old or younger. It means that if you feed your newborn with this formula, you will not have to switch to any other brand when he turns 6 months and older. Similac advance or Similac sensitive are not recommended for kids over 1 year old but there are different products available from the same brand which you can choose even after your kid has turned 1+ years old.

Both of the products have the same basic nutrients with just slight differences.


Frequently Asked Questions( FAQs )

When Should You Switch To A Sensitive Formula?

You will know whether your kid is lactose intolerant before you are discharged from the hospital. In addition, if you are nursing, you will need to initiate with the sensitive formula immediately. If you wish to breastfeed, your physician will advise you based on your child’s lactose acceptable limits.

Well as a parent, you should not expect any tolerance issues. However, for additional and accurate medical advice, always ask your physician.

Is Optic Growth And DHA Allergic?

OptiGrow and DHA are not allergic. They sometimes cause bad digestion if your baby is weak but that is not a big issue.

Which Similac Formula Is Closest To Breast Milk?

It is critical for moms who need or want to utilize a formula to get as close to breast milk as feasible.
