Personally, I've found how they aggregate research and list it a valuable resource for how I continue my own research on a particular supplement.

I find it much more valuable than the empty Mayo Clinic and WebMD articles that are so conservative in the information they provide that it's basically just reading common knowledge.

I think if you're using one site for your source of information for supplements, you're doing a disservice to yourself and potentially putting your body in harms way. So, with that said -- I also do not think Google should be removing this from their search results.
