Given that Whole Foods, along with GNC, has been all over the news for months and subject to investigation for selling all kinds of "wholesome and natural" things that are mislabeled and often don't even contain what the labels say they contain, why would you even consider this? Just because something is "organic" or whatever doesn't mean it's safe. Think poison ivy, snake venom, toadstools and bella donna. And what about the interactions of these products, given that they are plant based, with medications which have some plant basis and some chemical basis? And now you're adding alcohol, although what's in the non-alcoholic products may be even worse.
I work in food science and am a strong believer in certain supplements, presuming they are tested and patented (so the label is proven to represent what's in the product) and presuming they have the FDA Good Manufacturing Practices designation. Certain non-drug products are not "FDA approved" because they are food based, and that's okay if other criteria are met. In fact, it may be better, since many of the other products (considered "drugs" and not "food") will have warning labels (from children's vitamins to many other products). But you don't know that unless you know exactly where the product is manufactured (and not whether it has a pretty label or some health claim on a holistic blog). What clinical data are you using? What trials has the product been through? Are the ingredients brought into the manufacturer's location with a certificate of analysis from the supplier, are they quarantined, and are they tested again?
Moreover, as any food scientist will tell you, and as your casual and nonscientific experience has shown you, single nutrients don't work very well. That's not how the body is designed to absorb nutrition. So you are wasting money and time, and perhaps even fooling around with your kid's health. I work with kids (and adults) all the time who deal with asthma and nebulizers and inhalers, and we only use a comprehensive children's supplement with far more than one or two ingredients, and properly balanced. It also needs to be totally allergen free and compatible with medications.
I think you're missing the boat here, and possibly making things much worse. Sorry - I know this is not the answer you want to hear, but I really don't think you have gotten your shopping information from any credible source. Just because it's on an internet blog doesn't mean it's scientifically sound. I work with experts in pediatric nutrition and I've never heard of any the ingredients you're latching on to as being proven effective.
