  • 3 months ago i switched to this formula so far so good Sep 03, 2023

  • We switched my baby to this after she kept throwing up after feeds and she has done amazing on it. Apr 27, 2023

  • I personally think it stinks and the smell stained my baby's bottles and nipples but it definitely helps diarrhea and or lactose intolerance issues Dec 03, 2022

    What I loved most about this was the gentleness it provided for my baby girls stomach. When I first gave my baby milk based, it made her sick. Switching to Soy was the best thing we did for our girl. Jul 05, 2021

  • My baby has a diary allergy and this formula was a win for us! May 03, 2021

  • I do appreciate the fact there is no palm oil in this brand. Apr 12, 2021

  • Formula works good for my daughter. Just dont like that if you don't shake it enough the formula it clumps and if you shake it too much it gets really foamy. Mar 28, 2021

    When my baby was having hard stool and lots of spit up we went through a few different formulas (sensitive, hypoallergenic, etc.). We finally tried the soy and had success! He loves it too. Aug 06, 2020

  • This is one of the only formulas my daughter can drink and lot have projectile throw up Jul 03, 2020

  • This made a night and day difference with my son when he was 2 months and we figured out he had a milk intolerance Mar 27, 2020

    • Heidi D.

    • Philadelphia, Pennsylvania

    This is the only milk (including both formula and not formula) that my baby will drink, and we've tired it ALL! He loves. Doesn't upset his stomach at all. Feb 17, 2020

  • Tried this when my little was experiencing gas, frequent spit ups and tummy aches with regular formula. This caused severe constipation and left him miserable. Jan 02, 2020

    • Ella D.

    • Lexington, Kentucky

    I was exclusively breastfeeding and around 3 months my daughter started being constipated and colicky someone recommended i try giving soy every other time and it made a difference within a day. Dec 19, 2019

  • I love this formula. my daughter had problems with vomiting and diarrhea and this is what I use so she doesn't have those problems anymore Aug 07, 2019

  • My son did not do well with original and was fussy and gas. He still has gas but not as much and barely spits up!! He seems to do well with his formula. May 15, 2019

  • We tried several formulas with my son for gas and spit up and this was the only one that worked. If your little one has issues definitely give this a try. Aug 31, 2018

  • Baby does great on every other soy formula besides Similac. Made him projectile vomit and spit up a ton. He cried a lot the couple days he was on it which I assume was due to belly aches Jun 08, 2018

  • My son who is diary intolerant does great on this formula Apr 27, 2018

  • Baby had a milk protein intolerance. Tried every type of formula and nothing settled. Tried Enfamil soy formula and baby still spit up and gassy like crazy. Similac soy seems to have a better balance Apr 08, 2018

  • My baby was very gassy and fussy - we switched to Similac Soy, and he became the happiest baby around! Apr 06, 2018

    • Mandy D.

    • Chapel Hill, North Carolina

    Used it for a bit when doctor thought my baby was not responding well to formula that uses dairy, and she didn't mind it. Strange taste that took baby time to get use to, but nice option without dairy Apr 05, 2018

  • Made my little girl supper gassy and fussy. Found out she had mspi so not entirely the formulas fault. Feb 01, 2018

  • My son is allergic to milk proteins. This is the only formula that worked for him. Jan 24, 2018

  • When my son was born he had a lot of gas and colic issues until his pedi put him on soy! Since then I’ve had one happy baby thanks to this formula! Dec 19, 2017

  • I want to love this because it has helped my baby be more comfortable, but I do not like that soy formula contains high amounts of sugar. It also is an unpleasant smell in and out :( Oct 29, 2017

  • This formula is a miracle worker! we went from advanced, to sensitive to soy (all similac) and this is by far the best for spit up and gas Oct 10, 2017

  • My son had to be on a soy based formula and this was the only one he could keep down. i love similac i would never purchase any other brand Sep 27, 2017

  • Baby likes and enjoys as much as breast milk. Sleeps heavy afterwards. No tummy issues. It is expensive and does smell a little funny, but so worth it not to give her cows milk products. Jun 28, 2017

  • I feel that this was very helpful for my baby. He used this until he started drinking whole milk. Apr 18, 2017

  • Gave my baby stomach pain. Feb 18, 2017

  • I switched to this when my son became lactose intolerant. It did not disappoint at all! Jan 23, 2017

    Worst formula ever. My daughter was put on this as a newborn and it made her so constipated. I couldn't believe her bowel movements as a baby. She would scream bloody murder it hurt so bad. Jul 29, 2016

  • I stopped breast feeding when my daughter turned a month old, and switched to Similac Soy due to a milk allergy. Great stuff!! Jan 29, 2016

    • Cara S.

    When my son had to switch from BF to formula this was the only one he would tolerate. It worked great for about 6 months. Super expensive but i wouldnt use anything else. Feb 23, 2015

    Used for a little while, then my baby was too sensitive and had to switch... She spit up wayyyy more on this formula Feb 03, 2019

  • Had to switch my baby to this because they think he might be lactose intolerant. He seems to enjoy it and it mixes really well. The formula has a pretty bad smell though. Feb 19, 2018

  • This formula was heaven for our little one. The hospital started her on the Similac advance and poor thing threw it up everywhere. This made her full and happy. She loves it and her tummy does too! Dec 16, 2017

  • Best formula Jun 20, 2017

  • We use this daily with our current and used with our first. It was the only thing that seemed to no upset their little tummy. May 03, 2017

  • My child was allergic. Terrible experience. Jan 06, 2016
