Vitamin

Understand the mechanism before acting on health claims.

  1. The useful idea

    Vitamins are organic molecules (or a set of closely related molecules called vitamers) that are essential to an organism in small quantities for proper metabolic function.

  2. How it works

    These essential nutrients cannot be synthesized in the organism in sufficient quantities for survival, and therefore must be obtained through consumption.

  3. Why it matters

    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.

Use Vitamin to ask clearer questions; personal health decisions still belong with a qualified professional.
