The kids use their products. Just putting it out there while they say there are no undisclosed ingredients they do have some undisclosed proprietary flavorings which they will "yes/no" if you ask if it's in there. The problem is that you have to play your odds that you're asking for the right allergen.
The first is hops which I initially was concerned was related to barley (one child ana to barley). Despite being in beer with wheat, barley and rye, hops is completely unrelated. I confirmed this with a university senior researcher in plants.
The other is chamomile (aster family) which affects a couple people here I think.
Not a huge deal if you're concerned only with top 8 but there's some flavoring surprises that won't be disclosed. However, if you go to the flavorings page on the website you could at least whittle down which flavorings you need to inquire about. I respectfully requested that for the sake of consistency in order to fulfill their statement that all ingredients are disclosed that they actually do it. Right now not only are there undisclosed flavorings which won't be revealed specifically unless you guess correctly, the product ingredient list online doesn't always match the label on the product itself.
