I received my Building Blocks sample pack this weekend. I tried them tonight, and overall they are chalky. I did like the Black Raspberry Iron chewable though. I'll post more about these vitamins, but right now they are not in the running for my vitamin regime.
I have had problems recently with acid reflux, and the night I took these vitamins it was worse. I'm not sure why. Last night, I stopped drinking water an hour and a half before bedtime and I still had problems. I'm going in for a little unfill to see if that helps. Trial and error.
