Drawing on my own experience as a former medically complex foster parent, hours of research, and speaking with current preemie parents, I’ve included a list of the best formula for preemies plus hypo-allergenic premature infant formula alternatives and answers to the most frequently asked preemie feeding questions. No matter what your doctors recommend, you can explore these best formula for preemie options that I’ve outlined below.Best Preemie Formula Overall: Similac NeoSure Formula
Best Organic Preemie Formula: Similac Organic Non-GMO Formula
Best Preemie Formula
Similac NeoSure is specifically formulated for premature infants. The intent is to provide extra calories and increased protein, energy, vitamins, and minerals for accelerated growth through the first year of life.
All formulas contain those categories of ingredients but the concentrations are higher in formula made for preemies than in other formulas. The objective is to see growth in the key measurements including head size, weight, and length.
NeoSure is an easy-to-digest milk-based formula.
- So exactly what is NeoSure formula? This formula includes:
- DHA and ARA – these additives have been shown to complement eye and brain development in some studies, and are also found in breast milk
- Calcium and Phosphorus – for baby’s growing bones
- Lutein – for eye development
- Vitamin E – cell development nutrient also found in breast milk
Similac claims that “Preterm infants fed Similac NeoSure through the first year of life showed significantly increased lean body mass and less fat mass at 12 months corrected age.” Studies have shown that preterm infants using this formula had improved visual acuity at 6 months corrected age, as well as improved early language development at 14 months corrected age.
It should be noted that some parents reported excess gas and increased constipation upon starting this formula. However, this seemed to resolve itself after continued use. Similac NeoSure comes in three preparations – 2 fl. oz. ready to feed bottles, 1 qt. container of ready-to-feed formula, and a canned powder to be mixed with water.
This best formula is named “Best Formula for Premature Babies” on our Best Baby Formula list, too.
Gerber Good Start Soothe HMO Formula
There really just isn’t a lot on the market in the way of preemie formulas. For a lot of preemies, the two or three main options might not work. Giving a regular formula a shot isn’t out of the question. They may be free from extra protein or extra nutrients, but they definitely have everything your baby needs to grow up strong and healthy.
What I like about this Gerber Good Start Soothe HMO Formula is that it’s pretty close to being a Gerber premature formula. It has HMO in it, which is Human Milk Oligosaccharide. This is a prebiotic that’s found in breast milk and it’s really good for baby’s digestion and immune system development. Many moms of premature babies want to give their baby breast milk or something really similar since it’s been proven to be the best nutrition that you can give a preemie. This HMO also makes the formula really easy for an underdeveloped tummy to digest.
The other thing that makes this a really good premature infant formula is that it has what Gerber has coined “comfort proteins.” They take high-quality whey protein and partially hydrolyze it. What this does is breaks down the proteins into smaller particles and make them easy to digest and absorb. This works in preemies’ favor, and it’s also good for babies with colic, gas, fussiness, or other troubles related to eating.
Other bonuses include probiotics, DHA for eyes and brain development, and free from artificial growth hormones. Overall, this is a great choice for feeding your preemie. It’s the first regular formula to try.
Enfamil NeuroPro Enfacare
Enfamil NeuroPro EnfaCare like NeoSure was developed for feeding premature babies during their early months to achieve growth targets. With enriched nutrition and expert-recommended levels of DHA and ARA, Enfamil EnfaCare is a milk-based formula that supports your baby’s healthy development.
The formula was improved in 2018 to add in MFGM (milk fat globule membrane) to help support brain development. It’s an ingredient found in breastmilk which makes this a stellar option for preemies.
Enfamil says “Premature babies fed this formula during the first year have achieved catch-up growth similar to that of full-term, breastfed infants.” This formula comes in three preparations – 2 fl. oz. and 8 fl. oz. ready to feed bottles, and a canned powder to be mixed with water. Parents reported more stomach discomfort with this formula versus its competitor and it also has corn syrup solids which some parents don’t like.
Similac Organic Non-GMO Infant Formula
When in doubt, go organic to give your preemie the most possible nutrition. With Similac Organic Non-GMO Infant Formula you get high quality formula without antibiotics or rBST-milk. Moreover, organic nonfat milk is the first ingredient in this formula.
Not only did they leave out GMOs but also pesticides and other creepy ingredients. You won’t even find corn syrup on the list as the company opted to use organic sugar instead, which is rare. Also, you won’t see palm oil on the list either instead, they opt for sunflower, soy, and coconut oils, which are healthier for your baby.
The only downside of the formula is it uses maltodextrin, but it is organic, which is a second sweetener, from a natural source. Otherwise, you get beneficial ingredients like DHA, vitamin E, nucleotides, and antioxidants along, with all of the essential vitamins and minerals.
Make sure to talk to your doctor before using it for a preemie as your doctor may suggest a formula designed for preemies first. However, if the doctor says this is the right option, you can use it for the first full year of your baby’s life.
Hypoallergenic Preemie Formula
If your baby needs a hypoallergenic formula, I urge you to consult with your child’s pediatrician or nutritionist to avoid any stomach issues. There are many options available to you. Most commonly, it will be suggested that you try Similac Alimentum, Enfamil Nutramigen, or Neocate. However, instead of the standard preparation, your baby’s healthcare provider will suggest a specific recipe for preparation to ensure that your baby gets the correct amount of intended calories. Please speak with a healthcare provider before making this change. Not enough calories will result in poor weight gain. Too many calories may result in a host of tummy troubles and issues.
Selecting the Best Formula for Preemies
Science Direct, a leader in scientific, technical, and medical research, states that many very preterm infants receive formula milk as a major source of nutrition during their hospital stay because human milk is not available. Standard term formula is designed for term infants, based on the composition of mature breast milk. The concentrations of protein, calcium, and phosphate are not sufficient to provide the recommended nutrient needs for stable and growing preterm infants.
Therefore, preterm infant formulas should be used. According to Gerber Medical, the overall goals for ongoing nutrition of the preterm infant are to continue to meet their increased nutritional needs to safely support catch-up growth and development while supporting GI function and helping to build their developing immune system. The best preemie formula will contain the right amount of protein, which is an essential requirement for babies born at an early postconceptional age, and has a good protein/energy ratio, per expert recommendations.
Similac NeoSure and Enfamil NeuroPro Enfacare have been specifically formulated for preemies because they have been enriched with nutrients like calcium, magnesium, and phosphorus. They also have more calories and a higher protein level. This formulation is made to help your baby gain the essential lean mass that they’ll need to leave the hospital and get onto regular infant growth charts.

- Higher calorie count
- An increased amount of protein
- Enriched nutrition
- Proven growth benefits
- Warming formula in microwaves is risky because it can cause serious burns.
- Since premature infants may not have fully developed their immune systems, caution should be taken with powdered infant formula. Powdered formulas have been found to contain contaminants and should only be used on the recommendation of your doctor, following procedures to reduce the potential of infection.
