I've been really happy with this supplement. I feel like my kids get most of their vitamins and minerals from their diets except when it comes to DHA and omega 3's. We don't eat a lot of fish and to be honest I'm not even sure what foods have DHA other than fish. From what I have read DHA is important for brain function, so I prefer to make sure they are at least getting DHA in a supplement. I see no side effects to taking these. The kids love the taste and actually ask for them if I forget to give them their vitamins. For me, I'd rather give them the supplement than nothing. A serving is two gummies has three grams of sugar. It seems like a lot of sugar for such a small serving. They feel like they're coated in sugar. I've never eaten one myself. I know the kids think of them more as candy than anything else. I think the price is reasonable. This is actually one of the lowest priced brands I've looked at. I know there are others with all natural ingredients, but when I compared costs, I had to go with this one.
