A natural form of vitamin D that is produced in the skin when exposed to sunlight and is also found in certain foods like fish and egg yolks.
Cholecalciferol is important for maintaining healthy bones and teeth.
Cholecalciferol is formed from "chole-" (from Greek "chole", meaning bile), "calcifer" (from Latin "calx", meaning lime or calcium), and "-ol" (a suffix used in chemistry to denote alcohols). The word refers to a compound related to bile and calcium, specifically a form of vitamin D produced in the skin upon exposure to sunlight.
Think of 'bile' ('chole-') and 'calcium' ('calcifer') coming together in a compound that helps your body absorb calcium — that's what cholecalciferol is all about.
