There are many healthcare supplements in the market; ONLY a few come with the Lancet report.

The lancet is the most credible medical journal. It publishes original primary research and review articles of the "highest standard."
The journal is now the world-leading clinical oncology periodical publishing high-quality, peer-reviewed research (primarily reports from clinical trials), reviews, comment, opinion, weekly news, and commission (typically in partnerships with societies, governments, NGO's, and academic center's).

Thus, having research on PPARs published in the lancet is very promising.
