Similac Alimentum vs. Enfamil Nutramigen: Which is Better for a Baby?

Baby formulas aren’t all the same – some of them contain good nutrients for your baby while others don’t have enough. While they are not a complete substitute for breast milk, it is sometimes inevitable that in some cases, the mother may not have the capability to produce enough for her baby.

A common case of moms having to stop their breastfeeding is when their baby gets colic or the inability to digest milk protein properly, which can lead to stomach upsets and excessive crying. Colic is usually triggered by breastfeeding because your baby may be unable to digest the milk proteins in your breast milk. This is why, if this happens, you may want to turn to a colic specific infant formula instead.

Therefore, it is important to choose the most ideal infant formula, compare products, and rule out those that might not be good for your baby.

The Showdown: Similac Alimentum vs. Enfamil Nutramigen

In this article, we compare the different aspects of Similac Alimentum and Enfamil Nutramigen as baby formulas.


Both Similac and Enfamil have a similar formulation – using a pre-digested version of cow’s milk protein. This type of protein is known to be ideal for babies who have allergic reactions to natural cow’s milk protein and usually have stomach upsets such as colic and other signs of allergies.

In addition to that, this kind of formulation may also help babies to reduce excessive crying that’s caused by such protein sensitivity. Therefore, if your baby has problems with colic with normal baby formulas, these two are good formulations to consider.

It is always important to know what is in the formulation of your baby’s milk. This is because there can be many baby formulas out there that do not explicitly display and verify their milk contents and offer their product at a low price, which can be dangerous for your baby’s health. Therefore, you should always have a baby formula that has a good formulation so you will know if it will potentially cause allergies to your child or not.

Winner for this round: both


In terms of price, Similac is less expensive than Enfamil, most probably because it is a newer brand than Enfamil, which has been a long-time contender in terms of baby formula. While you can order more cans in bulk, the individual price per can is pretty different from each other, and Similac seems to be more budget-friendly.

Price can be a deciding factor for most moms who are saving on their budget and yet want to feed the best formula for their baby. While it should not be a deciding factor, the price of a product that is consumed regularly, such as infant formula, can potentially add to your daily expenses.

The additional expenses can be troublesome if you don’t have a lot of cash on hand and need to work harder to sustain your baby’s needs. This is why most moms go for the cheapest formulation possible but without compromising quality overall.

Winner for this round: Similac


Both Similac and Enfamil have a similar formulation – they are both soy-free. This type formulation is important for babies who have intolerance or allergies with soy. This goes along with the fact that they are formulated with a pre-digested version of cow’s milk protein, which can help babies a lot in terms of reducing allergic reactions not just to milk protein but also to other substances like soy.

Not many formulations of infant milk in the market are free from soy, which might not be ideal for some babies. This is why both these products can be great for such instances, in which the extra price may pay off as compared to cheaper formulas out there that you might not be so sure with their formulation, if they are safe for your soy-intolerant baby or not.

Winner for this round: both


In terms of packaging, Similac is generally good, although there were some complaints of the scoop of the formulation being bigger than it used to be, while there is a fewer formula in each can, which people may see as less value for their money in the long run. Similac has 12.1 ounces of powdered formulation in each can, which is less than Enfamil’s content.

On the other hand, Enfamil is generally good as well, in terms of packaging, with minor reports of inconvenient packaging, but nothing very alarming in general because it depends on the shipment of the product and other external factors such as handling. Enfamil has 19.8 ounces of powered formulation in each can, which is more than Similac’s content.

There is a big importance with the right packaging for a product. This is because, without a good packaging, the buyer might be turned off with the contents of the said product. In terms of infant formula, it can be a delicate and deciding factor because it is something that is consumed by your baby. Anything wrong that goes with the formula can have an impact on your child’s health in the long run.

Winner for this round: Enfamil

Enfamil Nutramigen

Smell and taste

Similac, like most colic specific formulas for babies, might not smell good in comparison to regular formulas that come with normal cow’s milk protein. This is why your baby might not like its taste in general, as well as its smell. In both terms, Similac seems to be unfortunately rejected by most babies who tried and tasted it, along with the awful smell as described by parents.

Enfamil also has an awful smell and taste, but there are some parents who noted that the taste is a little better than that of Similac in general. Both of these infant formulas are made with pre-processed milk protein, so it is in no surprise that they may both have the same features – an off-putting smell and taste. However, that is the problem that comes with nearly all colic specific formulas, anyway.

Having a good smell and taste is important not just for the parents but also for your baby. If the taste is bad then your baby might refuse to drink it, and your efforts and money might get wasted along the way. On the other hand, because these two are specially formulated for babies with colic problems, if you can get through the bad smell and taste as compared to regular cow’s milk formulas, your baby will be rewarded with a healthy milk formula without the annoying allergies.

Winner for this round: Enfamil

For babies with reflux

If your baby has acid reflux problems, both Similac and Enfamil have the capability to lessen or even completely take out your baby’s reflux problems in general. This is because they are both formulated for your baby’s digestive system to easily process to avoid such reflux problems from happening.

Having acid reflux for a baby is very confusing, frustrating and annoying for both the baby and the parent(s). This is because it can be painful for your child and they may start crying for hours and are unable to tell you what is wrong with him/her due to the inability of talking, so it can also be hard on your part.

Most likely, excessive crying is caused by acid reflux, and not all infant formulas can put an end or lessen such a thing from happening to your baby, because their formulations were not very friendly for your baby’s stomach. Being able to digest the formula properly is important for a baby because their tummies are not as strong as ours just yet.

Winner for this round: both

Can be mixed with breast milk

While it is true that both Similac and Enfamil can be used as replacement for breast milk if your baby has sensitivities to milk protein and has colic, which might come from breast milk, if you still want to be able to give your baby the best nutrients from your own natural milk, you can mix any of these infant formulas with it.

There’s always the words of health professionals: “breast milk is still the best for babies up to 2 years old”, which is true, anyway. This is why you can still mix your colic specific infant formula along with your breast milk in order for your baby to still get important nutrients from you, as their mother.

Winner for this round: both


Our clear winner is the Enfamil Nutramigen because it excels in terms of packaging, smell, and taste, as compared to Similac Alimentum. While both are soy-free formulas for babies with colic problems and acid reflux, Enfamil is more worthy to buy because of the better taste, which is important for the babies who will feed on it.

While Enfamil is a little pricier, remember that higher quality products are often those with added costs, so it is definitely worth buying, anyway. What do you think – which of the two brands do you prefer for babies with colic problems? Let us know in the comment section below!
