Good course of Iron
This product has helped my babies grow strong from their preemie NICU days to their first birthday. This iron supplement has come a long way for us.

Baby Enjoys It!
Been giving this to my baby since a week after we got home from NICU and she no longer has issues with the cold. Having her in the winter time, with her also being 6 weeks early, she needed that extra boost of iron for many reasons. Definitely see an improvement in her. She struggled with the drops backing her up a bit (iron supps naturally do that) but mixing it with the Gentlease formula has made her life SO much easier.

Good Product
My doctor recommended this for helping bring my toddler’s iron levels back up. Mix in with some apple juice and she drinks it all. I think it’s cheap enough and my toddler has been sleeping better. I didn’t even know low iron can affect sleep!

Mixed feelings
It’s a difficult trade off when your child needs something for their health but then it affects them in another way. My daughter has anemia of prematurity and we were advised to get this, but the iron really constipates her. We switched to the poly-vi-sol with iron and still constipates her but when she no longer needs iron we are planning to use the poly vi sol without iron.

Very grateful for this supplement
Our son has had nose bleeds for quite some time. Lately it was every day, sometimes numerous times a day. Our pediatrician checked his iron levels and saw that he was anemic. She prescribed this supplement and he went from daily nose bleeds, to not having one in almost a week! All of our family is extremely grateful!

Terrible on my daughter Tummy
I’m shocked at how many parents are showing their appreciation towards this supplement. It did not work well for us at all. I would give my daughter the drops, after her meal, and she would wake up out of her sleep puking uncontrollably. It was so bad to the point that she gagged every bit of everything that was on her stomach and even beyond that. It saddens me because we really want an easier way to get her iron up but this was not it. After contacting her pediatrician, they recommended we gave half of the Dose in the day and the other half at night. Still same results.
