What cookies are
Cookies are small text files that a website stores on your device. They allow the site to recognise your browser on a later visit, remember a preference, or measure how pages are used. Some cookies expire when you close your browser; others remain for a set period. They do not run programs and they do not deliver software to your device — a cookie only carries a small piece of information that the site itself can read back.
Because the site is an editorial resource, cookies help it behave the same way for every visitor. They let a page load with the display state you last chose, and they let us see which ingredient guides about natural supplements for men and which men's vitamin formulas are read most often. Nothing about a cookie changes what a page says.
