I thought the opposite: It campaigns against vitamin D as if it were a wolf in sheep's clothes. I've seen the author (and her partner) post and link about the dangers of vitamin D for a while now and it seems very unscientific to come at a subject with your mind already made up.

The author has clearly made up their mind about vitamin D and now they've made it duty to lobby on behalf of that belief, but I don't think they're capable of honest, unbiased science regarding this subject anymore.
