Back in August, I had to start giving A formula to get him enough to eat due to a dwindling supply. I discussed my search for an organic formula here. I decided to go with Baby's Only organic dairy formula by Nature's One. You may have noticed Nature's One made the news recently, and not in a good way. The first ingredient, brown rice syrup, has been found to have dangerously high levels of arsenic. Nature's One is responding that they use reputable third party distributors and will test all their products for high levels of arsenic. Thankfully, A has moved on to whole milk. We had 2 cans of formula we were going to finish up, but I guess we won't. The news seems inconclusive right now, but until you know for sure, I would avoid products with brown rice syrup, especially if it's one of the first ingredients. My second go-to formula during the time A was using formula was Earth's Best Organic Formula. This would be my suggestion, as A took it well and didn't have any problems transitioning between the two.
