Vitamin
Nutrients required by organisms in small amounts
Vitamins are organic molecules that are essential to an organism in small quantities for proper metabolic function. These essential nutrients cannot be synthesized in the organism in sufficient quantities for survival, and therefore must be obtained through consumption. For example, vitamin C can be synthesized by some species but not by others; it is not considered a vitamin in the first instance but is in the second. Most vitamins are not single molecules, but groups of related molecules called vitamers. For example, there are eight vitamers of vitamin E: four tocopherols and four tocotrienols.
The public source identifies “Vitamin” as nutrients required by organisms in small amounts. This brief keeps that definition visible, then builds a research path around Vitamin, Nutrients and required.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Vitamin”, the useful work is to connect “nutrients required by organisms in small amounts” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 28, 2026.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
