Five of the nine authors are apparently employed by The Wellness Company, which is in the business of holistic mail-order supplements. Of the other four, one is an independent physician, one is at a cancer clinic, one apparently retired. The remaining author, (the corresponding author), is cited as being at the University of Michigan School of Public Health, but I cannot find him listed in their faculty. The paper was apparently submitted last year though, so perhaps he has since left. I should also note that the corresponding author provides a gmail address for correspondence, not his university email address.
