Similac Vs Enfamil – Baby Formula Comparison And Reviews

Mothers find it hard to make choices on the right infant formula. The pros and cons of Similac Vs Enfamil are often discussed a lot in health and parenting forums.

Today, you can find infant formula manufactured by different companies on sale in family stores and pharmacies. There are several varieties of baby formula prepared for infants and children in different age groups. Some of them are even customized to suit different health conditions and special needs for the additional nutrition that the baby requires.

All infant nutrition supplements are required to meet the specific health standards set by the U.S Food and Drug Administration (FDA).

Two major brands of infant formulas sold in the U.S are Similac and Enfamil. You can choose Enfamil OR Similac for your baby. However, you must know the advantages and differences between these two bands and the categories of infant formula products they have for making the best choice for your baby.

What Are Infant Formulas?

Undoubtedly, breast milk is the best food for infants. Mother’s milk contains all the essential nutrition required for the best nourishment of the baby.

Many studies in the past have reported that breastfed babies are known to have higher IQs and better health than non-breast-fed babies.  Researchers say that breastfeeding improves the health of both the mother and her baby. It also improves the emotional and mental health of the child.

Unfortunately, many mothers are not able to nurse their babies, and they are forced to feed their babies with infant formula, an alternative to a mother’s breast milk. Many a mother does not get time to nurse their babies as work commitments keep them away from home. Others can’t do it because of health or cultural reasons. In such cases, infant formula is the best replacement for mothers’ milk.

Infant formulas are made of cows’ milk or soybean proteins as base content. Different categories of baby formulas are available; even for babies with food-related allergies, lactose intolerance, or other health issues.

All infant formula products are fortified with essential vitamins, minerals, and all other nutrients. Brands like Similac and Enfamil produce several categories of milk replacements supplements to address the specific nutritional need of the baby.

It is safe to feed babies with infant formula, especially the ones produced under the strict guidelines of FDA specifications and rules.

Similac Vs Enfamil

Best And Most Popular Infant Formulas In The US

In the US, 90% of the infant formula market is claimed by 3 products sold by 3 companies. The biggest brand is Enfamil from Mead Johnson which occupies about 50% of the market share in this product category. Enfamil also has the toddler formula sold as Enfagrow. About 30% of the market share for this product is held by Similac formula from Abbott Laboratories, and 10% by Good Start Formula from Nestle.

In this article, we shall be concentrating on the benefits and advantages of Enfamil Vs. Similac as these two brands together hold 80% market share in the US for infant formulas.

Both Similac and Enfamil are high-quality mother’s milk replacement supplements. These companies are engaged in continuous research and development for years to produce the best quality nutritional supplements for infants. Their products contain carbohydrates, protein, fats, vitamins, and minerals required for the healthy growth and development of the baby. They are certified by the authorized government health agencies and comply with the guidelines of the FDA.

Both brands have similar products as well as several categories of supplements to cater to the particular health needs of children in different age groups and health conditions.

Some of their products contain arachidonic (ARA) and docosahexaenoic(DHA) which are polyunsaturated fatty acids (with omega 3 and omega 6). These fatty acids are essential for the infants’ mental and visual development similar to that of breastfed babies. Infants who are not fed on breast milk should be fed with iron-fortified formulas that contain DHA and ARA during the first 9 to 12 months of their life.

Enfamil Vs. Similac; Advantages And Differences

Now our discussion is turning on to Similac Vs. Enfamil.

After making an in-depth comparative analysis of both of these products, I have found only a few minor differences between both brands.

The actual Enfamil Vs. Similac advantages and disadvantages come to the fore only when we talk about the customized supplement product types they have developed for babies with special nutritional needs and health conditions. The primary products of both brands are the same as they contain similar ingredients and produce the same results.

Now let us look at some of the significant differences between Enfamil and Similac according to the nutritional values of various products they have on sale.

Primary Nutrients: Carbs, Protein And Fat

The two core products from them are Similac Advance and Enfamil Infant. Let us have a look at the differences among the prime products of these two companies:

  • Both contain 20 calories per ounce;
  • Enfamil Infant has a slightly lower amount of fat but a higher amount of carbs than Similac;
  • Similac Advance contains 6 grams of fat, 11.2 grams of carbs, and 2.1 grams of protein per 100 calorie serving
  • Enfamil Infant contains 5.3 grams of fat, 11.2 grams of carbs, and 2.1 grams of protein per every 100 calories serving;
  • Both the products contain a standard amount of Calories set by the FDA.

Mineral Composition In Similac Advance Vs. Enfamil Infant

Both the products have the same mineral ingredients in them. However, they slightly vary when it comes to the number of minerals contained in them. Similac Advance has a higher amount of copper while Enfamil Infant has higher amounts of magnesium, phosphorus, iodine, zinc, and selenium. An equal amount of iron and calcium is present in both supplements.

Vitamins In Similac Advance And Enfamil Infant

There is a considerable difference between Enfamil Infant and Similac Advance about the number of Vitamins in them. They contain all the essential vitamins, but they vary in quantity. Similac Advance has a higher amount of vitamin D, riboflavin, thiamin, niacin, and biotin than its rival. Whereas, Enfamil Infant is a better source of pantothenic acid, choline, vitamins B12, C, E, and K, folic acid, and inositol.

Vitamin A in both formulas is equal; Vitamin A is an essential vitamin for the healthy growth of infants.

Additional Nutrition In Similac And Enfamil

Similac Advance and Enfamil Infant have added some special nutrients to them. These are special nutrients like DHA that usually the baby gets from mothers’ milk only. Both brands have added DHA (an omega-3 fatty acid to their product.  Enfamil was the first to add Prebiotics nutrients in baby formulas which help the growth of friendly gut bacteria. According to a review article published in 2013 in “The Cochrane Database of Systematic Reviews,” the nutrient Prebiotics is beneficial for preventing eczema.

Should You Choose Similac Or Enfamil?

It is really a tough question to answer whether you should be choosing Enfamil Or Similac. Both the brands are offering high-quality infant formulas that contain all essential nutrients and vitamins required for the healthy growth of the baby.

These brands strictly adhere to the guidelines of the FDA and are approved by Government health agencies.

However, you can either choose Enfamil or Similac, depending upon the specific nutritional needs of your baby. Both brands have particular categories of products for infants with rare health conditions or nutritional deficiencies.

If you are interested in organic infant formula, the Similac Advance Organic formula is the best.

Enfamil has two excellent products for a normally healthy child, Enfamil Infant, and Enfamil Newborn. However, Similac does not have a special category of products for infants below 3 months, and its Similac Advance is meant for 0-12 months old babies.

Enfamil Newborn is specially formulated with prebiotics to help the babies’ natural digestive and immune system; also contains DHA and ARA required by the baby.

If your baby has a fat absorption problem, it is better to provide the baby with Pregestimil offered by Enfamil, but Similac does not have any specific product in this category.

Another doubt most mothers have is whether they should choose ‘powder or liquid’ formula for the baby. Honestly, there is no difference between them from the point of nutritional value.

Powder formula will not get contaminated easily, but liquid formula comes in ready-to-use form. You can also save a few bucks by opting to buy the powder formula as they are cheaper than liquid formula.

If you have decided to purchase the powder formula, then you have to make sure that you don’t add less or more than the recommended quantity per serve. If the baby has the powder formula in excess, it might upset the baby’s stomach. If the powder is not diluted well, it might also clog the bottle’s nipple.

Finally, what is preferred by the baby should be the deciding factor in choosing the powder or liquid formula.
