PubMed & DOI
PubMed is a free public index of medical research papers, run by the U.S. National Library of Medicine. A DOI (digital object identifier) is a permanent ID number for one paper. A link to either opens the original study behind a claim.
Where the word comes from
Both names are modern coinages, not Greek or Latin. PubMed is short for “public” plus “Medicine”: it is the public face of MEDLINE, the National Library of Medicine’s index, whose own name means “MEDLARS online” — MEDLARS being the library’s computerized literature index from the 1960s. PubMed opened to the public free of charge in the 1990s. DOI simply spells out its function — digital object identifier — a system publishers created in the late 1990s so each paper keeps one permanent address on the internet.
What it means here
Every research statement on our product pages carries one of these links. That is deliberate: a claim a reader cannot check is just marketing. A PubMed link leads to the paper’s summary, authors, and journal; a DOI link leads to the paper itself, and keeps working even if the journal’s website changes. Following the link shows what the study actually found, in what kind of subjects, at what stage of research. Readers are meant to click them — checking our sources is the point of publishing them.
