About SelfHacking
SelfHacking publishes research summaries on sleep, supplements, nootropics, hormones and longevity under the SelfHacking Editorial byline rather than under individual names. Each article shows the date it was last updated and, where it cites studies, lists the references at the end.
How we weigh evidence is set out on the methodology page. Questions about an article, or a study we should look at? Contact us.
Who runs SelfHacking
Marcus Christensen
Marcus founded SelfHacking and runs it. He sets the editorial policy above, decides what gets covered, and is responsible for every article published here, including the ones that need correcting. He is not a doctor, and nothing on the site is written as medical advice. Reach him through the contact page.
How SelfHacking makes money
SelfHacking sells its own PDF guides, listed on the Guides page. The site may also show advertising. We do not publish paid articles and we do not accept payment for coverage of a product, study or brand.
Advertising and affiliate disclosure
Some articles may link to products sold by other companies through affiliate programs. When an article contains affiliate links, a disclosure appears at the top of that article and the links are marked as sponsored. If you buy through such a link, SelfHacking may earn a commission at no extra cost to you. Affiliate programs and advertisers have no say in what we write or conclude.
Editorial policy
Articles summarise published research and list the studies they cite. Each article shows the date it was last updated. We prefer randomised trials and meta-analyses in humans over animal and cell studies, and we say so when the evidence is weak or mixed. If you find an error, tell us and we will correct the article and note the change.
Nothing on this site is medical advice. Consult a qualified professional before changing a supplement, medication or treatment.
