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
Rated 5 out of 5 by WONDERFUL Our little guy was allergic to cow's milk and we tried this Soy ready to drink and it's been wonderful. I needed to start supplementing at 4 months and I thought he would hesitate since he only drinks breast milk but he has no problem drinking it and there are no allergic reactions. August 2, 2016
Rated 5 out of 5 by Almost no spit up Since we made the decision to try Isomil, my daughter spits up next to nothing now. My only regret is we didn't try it sooner. Thank you Similac! July 28, 2016
Rated 5 out of 5 by Great product We can only use the concentrate liquid the powder doesn't work well with allergies I the family. But the liquid is great and so easy to use love it so much better then powder ever! This is great for the sensitive babies :) July 26, 2016
