Similac Alimentum Reviews

Rated 5 out of 5 by from works great my little one was switched to this, and is doing amazing. She is also on medication for acid reflux and the two combined makes her a happy baby. I just wish it came as 2 oz, 8 oz ready to feed bottles. i Love those for the middle of the night and a quick grab when your out. Also would like to have them as a 4oz ready to go powder package. that way i dont have to carry a container of powder around with me. if they had those two options working mothers like me would have a much easier time on the go. :)

Rated 5 out of 5 by from Wow, what a difference a day makes! I decided to try this formula as my son was still having painful gas and discomfort with the sensitive formula. I was using gas drops in every bottle. With the alimentum he is doing great! Belly bloat and painful gas are gone. He is also now having regular bowel movements. Trust your instincts if you think there is a sensitivity.

Rated 1 out of 5 by from Awful... my newborn stopped eating After using Similac Pro as recommended from the hospital, my one week old newborn developed chronic gas pain, fussiness, non-stop flatulence, and did not sleep. After doing as much research as I could, I switched him to this one. The smell is AWFUL, the taste is AWFUL and after 4 days of my newborn eating this, he has decided to stop eating. His gas has continued and has in fact worsened. This formula is so thin, so when he was eating, he was eating every 1.5-2 hours when before he was eating every 3 hours.

Rated 4 out of 5 by from Good Product, Questionable Service My 1 month old became a gummy smiling baby overnight after switching to the ready to feed formula. Saved both of us. However, it is very expensive and we have been advised by our pediatrician not to use the cheaper, powder version at this age. We contacted Similac for coupons to assist with the cost and they were extremely responsive - HOWEVER they mailed us two huge packages of all their other types of formula and only one can of the powdered Alimentum. Feels like they are wasting their money and resources on those packages. Certainly was a let down for us when we received it. Appreciate the thought I suppose.

Rated 3 out of 5 by from I also hate the can! Put it in the regular plastic similac tub with a hinge! And make it available in a larger size! I feel like I’m buying formula alllll the time.

Rated 1 out of 5 by from The liquid and Powder are not the same!!! Very disappointed! I always used the ready to feed since my LO was 1mo old . LO doctor told us to change milk said first it is very costly and LO has gotten better with her colic. I wanted to do the changes slowly so I decided to just get the powder, I was very disappointed, Wasted my money & how in the world same brand and name but has different ingredients! As soon as I gave it to my LO she started throwing up!

Rated 5 out of 5 by from This is a god send BUT it’s soooo expensive! My son had a 360 degree difference within a day on the ready to feed formula but the issue is the price. The powder version did not sit well with my baby but the rtf is great! Not to mention the awful smell the powder one has

Rated 5 out of 5 by from Highly recommend for babies with food sensitivities We have used this formula for both my daughters. I highly recommend for food sensitive babies. Also, I contacted Similac and they sent me free samples and coupons. Great company and great product. Only complaint has nothing to do with the product. It's just not clear how to earn points toward more free samples as I use coupons and purchase similac all the time yet still have 0 points.

Rated 2 out of 5 by from The ingredients are an issue When my child was born I was a breastfed advocate, but I had too little milk to give her. So I started her out on Gerber but she was breaking out so her doctor suggested Alimentum. The powder form was just awful it smelled bad and my baby did not like it so we switch to the rtf. Boy, what a difference, she takes it with some ease. My only issues with rtf is the price and how sweet the stuff is. Seems like a lot of sugar...

Rated 5 out of 5 by from Great Product 8 month old has a food allergy to egg, milk and wheat. I've breastfed since we came home from the hospital, finally at 6 months she was able to get an allergy test our pediatrician recommended a different formula that didn't agree with my daughter she then wrote a prescription for Alimentum and it's a LIFESAVER. I tried the ready to feed first before getting the powder mix. Still breastfeeding and using the alimentum as a supplement. It's also gentle on her stomach. Thank you Similac for your awesome product!!! I will recommend this product to anyone who has a little one with food allergy or colic.

Rated 5 out of 5 by from Lifesaver! Our son was diagnosed with a milk/soy allergy at 3 weeks. I changed my diet and tried to keep nursing but unfortunately due to his allergies and a continued upset stomach, broken out skin and rashes we stopped. We tried Nutramigen at the suggestion of our pediatrician but our little guy spit up constantly throughout the day. I read numerous mommy boards with the same complaint. They all suggested switching to the Alimentum ready to feed formula. What a difference it has made! He no longer constantly spits up, he finally has a clear tummy and his skin is baby smooth again. We are so relieved but wow the cost is outrageous!!! It is almost 5x as much to use the Alimentum ready to feed than a typical formula. I’ve signed up for the support program in hopes of getting some discounts or coupons but have gotten nothing. Its unfortunate that a medical condition requires this formula and it is breaking the bank!!!

Rated 5 out of 5 by from Fastest working formula! My fourth little boy has been dealing with tummy troubles since he was born four weeks ago. We’ve tried a few other routes and our doctor told us to give Alimentum ready to feed a try. It has been a life saver! We noticed improvement, almost immediately it seems. He has reflux, colic and constipation—I am so thankful that he is now so much happier! Thank you Similac for making such a great product for my baby!

Rated 2 out of 5 by from Helps but so expensive Our pediatrician told us to switch our 10 week old to Alimentum and we saw a noticeable difference almost overnight...but it’s so expensive! I don’t know how we can keep him on this.

Rated 1 out of 5 by from Terrible formula This formula smells disgusting. It literally smells like dog vomit and my daughter won’t even go near it. Upset that I wasted the money on it and now I don’t have formula for my baby.

Rated 4 out of 5 by from Great product, terrible price Our son has food sensitivity so we started using Alimentum. We introduced it with ready to eat formula and slowly transitioned him to powder. Once he started eating the powder he would scream during his bottles and refuse to eat. It was such a struggle for several days despite the Dr putting him on meds for reflux. Once we switched back to ready to eat formula the issue resolved. However, alimentum is super expensive to begin and the ready to eat is even more costly. This is very frustrating, parents who have to use alimentim are already going through issues with their baby, price of formula shouldn't become a concern too.

Rated 5 out of 5 by from Third Times the Charm My son started with Similac Pro Sensitive as a supplement while I breastfed and would spit up constantly. We then tried Similac for spit up when I stopped breastfeeding and he would still spit up a ton. He hadn’t gained enough weight at his 4 month checkup and I started thinking it was more than just acid reflux. I decided to try the Alimentum to see if there was a sensitivity issue to milk proteins and BOOM! Significantly reduced his spit up after the first day. It does smell pretty bad and the value size isn’t as much as the other value sizes even though it cost more, but it works!

Rated 1 out of 5 by from Doesn’t like it! My 4 month old just got put on this. He does not like the taste at all and won’t drink it. Gives a yucky look and turns away from bottle. Why is this?! What can I do?!

Rated 1 out of 5 by from Horrible product My son is a week old and his dr recommended Alimentum and when I gave it to him he was spitting up a lot then choked on it because it was thick mucus like spit up went to the hospital and they gave him 2 more ounces and he choked on his throw up again I will never get this again

Rated 4 out of 5 by from This formula helped our LO! Our LO had severe tongue and lip ties that prevented her from latching/breastfeeding, even after a laser dental procedure at 5 days old. I struggled to pump enough and supplimented with Similac Pro Total Comfort for the 1st 3 months. Our LO ate that formula exclusively from 3-6 months. All of a sudden at 6 months, she experienced explosive and constant diarrhea for 2 weeks. It got so bad that her diaper rash started to bleed.The pedicitrican recommended Soy formula which did lessen the diarrhea but it also gave her hives. So our 3rd option was Similac Alimentum. Within days her stool was back to normal, allowing the diaper rash to finally heal. She's been taking Similar Alimentum for the past 4 months. It is expensive and smells terrible BUT it helped us so much!! To offset the high cost, our pediatrician wrote a prescription so we're able to purchase it using FSA dollars (insurance). As we approach the 1 year mark, I'm terrified to try and reintroduce cow's milk. Fingers crossed!! Thank you to Similac Alimentum.

Rated 5 out of 5 by from Saved our sanity This by far is the BEST formula! It was a lifesaver for our little girl. She was breastfed for the first 6 weeks and developed the worst colic our pediatrician said she had ever seen. We tried so many different formulas and there was no improvement. She cried so much one day that I took her to the emergency room and demanded them to do xrays on her to see if something was seriously wrong. All they could tell me was colic. My husband, baby and I were miserable for months. Finally when she was 6 months old we tried this formula and our little girl was healed. No more crying, fussiness, and gas! It was the first time she smiled and laughed. We couldn’t be more grateful for this formula.

Rated 1 out of 5 by from Vomiting after use My daughter was on enfamil gentleease with diarrhea so I switched her to alimentum. I first tried the power and she vomited the whole thing so then I bought the ready to drink same thing, she vomited. So I just switched to nutrimegen. Hopefully she doesn’t have an reaction.

Rated 5 out of 5 by from Life saver! We used ProAdvanced at birth to 2 months and it was ok he was gassy and ate a tonnnnn then we switched to Gerber Soothe for about 3 months. My babies stools were basically half stool half formula, couldn’t get him peaceful, he had a horrible time with stools, cried, and just was so gassy and uneasy. My doctor recommended us putting him on this. It’s double the cost but worth every dollar the last 7 months. He has easy stools, a regular stool, hasn’t had one upset stomach nor any signs of colic nor gas since the day he has started this formula. It has been a life saver. The smell isn’t the best but it’s formula so who cares. The biggest can defiantly gets your further along. He has been the happiest most comfortable baby since the day we introduced this! I couldn’t say enough good things about this product and I recommend it to everyone! So thankful for this!

Rated 5 out of 5 by from Peace of mind I had a premature child and once my breastmilk stopped we tried neosure then pro total comfort (caused gas,spit up), sensitive (refused) then soy (refused all except 1.5 oz.).. went back to neosure until we could figure out our next step, it (and soy) caused him to get congested and rashy.. it's been half a day and he isn't as gassy, seems more relaxed and most of the rash is gone.. he absolutely loves the taste and drinks more than previous formulas and can't wait for it to take full effect.

Rated 4 out of 5 by from Great formula/ Horrible container PRO-After trying 6 different formulas we tried this one and it was the magical formula that worked. We noticed a change within a week, my baby's acne had completely resolved, he didn't have horrendous poops or loud farts/belches, he wasn't throwing up 1/2 or more of his feedings, and his colic 100% resolved. I would recommend this to anyone that has tried sensitive tummy formulas and are still having issues. However I would try different brands of the sensitive tummy milks before resorting to this. All babies are different and what will work on one might not work on another, also there is quite a few store generic brands that might be more cost effective. Because well lets be honest this milk is super expensive. I am going through a 19.8 oz can every week at 40$ and my baby is only 3 months old drinking 3 oz at a time. I am on a fixed income and unfortunately Similac does not send out enough coupons/checks. The welcome package was nice and we had checks that lasted that first month, but they don't sent them out as frequently as you need to purchase milk CON- You should make this milk available in the same quantity that you do the other formula that you offer. Before my son was on this formula he was on the similac pro-total comfort 22.5 oz plastic can. I miss this can and wish you would use it for the alimentum as well. The plastic can is amazing because it has a holder for the scoop so your not always digging around looking for it, the sides of the container are flat so you can get an even scoop, and the lid is a hinge which makes one handed (other hand holding baby) bottle making A LOT easier.

Rated 5 out of 5 by from Finally Something that Works My son tried 4 different formulas before we found this God sent Similac Alimentum! Before this formula my son had excessive gas, constipation and colic. About 3 days after feeding him the ready to feed formula he was a much better baby! He would only cry if he was hungry. Though the ready to feed is on the pricey side it is definately worth your baby not being in misery.

Rated 4 out of 5 by from Great product in ready to feed The ready to feed was the seventh formula that my son tried and it finally worked! He would scream all day long and was in horrible pain after eating. Before this we did try the powder and like the reviews I have read, it is a different formula from the ready to feed. My son broke out in a horrible rash all over his face, neck, and head. His ears became like sandpaper. With in the first 24 hours of trying the ready to feed I noticed a significant difference in my son. my only complaint is that its super hard to find and very very very expensive. The larger container also leaks out when you pour it which is annoying since it isnt exactly cost effective. I also am having a hard time finding a store that carries the 8oz cans.

Rated 4 out of 5 by from Ready to feed vs. Powder- Why would they not be the same? Love the ready to feed Alimentum for my 6 week old. With my baby, this vs. other formula has been a night and day difference. We started with Enfamil Infant which caused a lot of spitting up and gas. We then switched to Similac Pro Advance which Everything seemed worse. From that we went to Sensitive and Pro Sensitive with no change. He was miserable and he would cry all day long. We decided to try the ready feed Alimentum and noticed a difference with the first bottle because he did not fuss and drank the entire bottle. Once I saw he did amazing with the ready feed Alimentum I bought the powder (Thinking IT WAS the same) boy was I wrong. His reaction to the powder was the worst I have EVER seen him. He was only able to get one once down and he kept bowing his back and had the worst gas. He screamed at the top of his lungs and puked. I decided the next day to give it another go because, let’s be honest, $40 is a lot of money when you are a family of 5. He had the same reaction. Reading the ingredients on both they are not even the same! The powder has corn. How could both of these be sold under the same name and be different? Now I’m out $40! The ready to feed I will definitely continue, but VERY disappointed with the powder.

Rated 1 out of 5 by from Food allergies with Eczema Our son is 9 months old and was breastfeed exclusively till 8 months when my supply ran low. He was diagnosed with eczema around 4 months which we used an elimination diet to help. We found that He couldn’t tolerate Dairy or eggs. We started supplementing him w/ enfamil Prosobee Soy formula but when we made the complete switch to strictly formula we noticed more eczema outbreaks that were becoming unmanageable. When I mentioned this to our Pediatrician she recommended the Similac Alimentum. I went out and purchased the lg powdered formula and made an 8oz bottle for his next feeding, he drank 4oz then instantly threw it up followed by a massive diarrhea diaper 20-30min later. He continued to spit up for the following hour I could only assume until he got it ALL out of his system. I can only assume from some of the prior comments that maybe it’s a corn allergy. I will not be buying this product again. Hopefully the store will take it back, if not I’m out $40.
