Rated 1 out of 5 by So constipated My baby was on this for aboutique a week and a half and got so horribly constipated. Awful, hard poo that hurt him to pass (you knew when he was going cause he would cry). He has a milk protein allergy so we thought this would be good, but nope. Don't know if he also has a soy allergy, but 10 days was long enough and I wasn't gonna try it any longer! October 15, 2016
Rated 5 out of 5 by So Far So Good This product has helped my son sooo much! We have been on Similac Sensitive, Spit-Up, & Alimentum all told by our doctor to try. Nothing was working. Finally, went out on a limb and tried Similac Soy- all I can say is "MIRACLE WORKER!". He doesn't fuss as much as he used too, if at all. He is taking longer naps, now that he is actually sleeping longer then 30 minutes. And sleeps all night long. He is getting the sleep he needs & so are we. If you have a fussy, restless infant, this product is a MUST TRY! Happy Baby!- Happy Parents!- Happy Home! Thank you! October 6, 2016
Rated 5 out of 5 by Love the product! This formula has changed our lives! The first two months was a guessing game as far as vomit, rash, fussiness, and diarrhea! Two weeks after starting this he completely cleared up and we started enjoying our time with our new baby! Happy baby = more sleep for mom = happier home! Way to go Similac Soy! October 3, 2016
Rated 4 out of 5 by Clumpy but wonderful This formula has helped my baby's tummy issues. The only problem I have is it doesn't mix well and clumps up so I have to make the bottle 5 minutes or so before I'm ready to feed him and then shake it again right before feeding and it usually breaks the clumps up.

Rated 4 out of 5 by Good formula when regular formula is not an option My son cannot have milk based formula due to a milk allergy, so this soy formula is great. The only problem I have with this formula, is that it doesn't dissolve as well as other Similiac formulas, which is very disappointing. It's irritating to know that expensive formula is being wasted since it doesn't dissolve 100%. September 12, 2016
Rated 5 out of 5 by Breast milk to formula After running out of breastmilk for our daughter before turning 1 we had to resort to formula. We tried 4 different ones but until we tried similac soy she absolutely refused to go anywhere near the bottle. So im happy to say this has helped us a lot so thank you Similac September 8, 2016
Rated 5 out of 5 by Great the second time around It worked well for my first daughter and is helping my second daughter with her fussiness,spit up and has issues. August 23, 2016
Rated 5 out of 5 by Life saver! After we went to strictly formula, we had a hard time finding one that our baby girl could tolerate. We tried everything and everything caused her to spit up, she was extremely fussy and overall not happy. Finally we switched to Soy Isomil and we have had no issues and she has been the happiest little girl! August 18, 2016
