ANTIVITAMIN Meaning and
Definition
-
An antivitamin, also called a vitamin antagonist, refers to a substance or compound that has the ability to interfere with, inhibit, or diminish the biological activity, absorption, or utilization of various essential vitamins within the body. Unlike vitamins, which are essential organic compounds required for normal physiological functioning, antivitamins work contrary to these essential nutrients, hindering their function or blocking their absorption.
Antivitamins act by competing with vitamins for the same enzymes or receptors within the body. They may also act by modifying the structure of vitamins, rendering them inactive or less effective. In some cases, antivitamins can disrupt the conversion process of vitamins into their active coenzymes, thereby preventing the proper utilization of the vitamins by the body.
The presence of antivitamins can occur naturally or as a result of external factors such as certain medications or chemicals. Some examples of antivitamins include compounds like avidin, which binds to biotin and reduces its availability, or pyridoxine antagonists like isoniazid, which can interfere with the conversion of pyridoxine (vitamin B6) into its active form.
The effects of antivitamins can range from mild disturbances in vitamin absorption to severe vitamin deficiencies, which can lead to various health complications and diseases if not addressed promptly. Consequently, identifying the presence of antivitamins and understanding their mechanisms of action are important for maintaining optimal vitamin levels and overall health.

Etymology of ANTIVITAMIN
The word "antivitamin" is derived from two components: "anti-" and "vitamin".
The prefix "anti-" comes from the Greek word "antí", meaning "against" or "opposite". It is commonly used in English to indicate opposition, contrast, or negation.
The term "vitamin" originates from the combination of the Latin word "vita", meaning "life", and the compound "amine", as vitamins were initially identified as organic substances essential for life that contained nitrogen. This term was coined by Polish biochemist Casimir Funk in 1912.
Therefore, "antivitamin" refers to a substance that acts against or opposes the functions of a vitamin. It is used to describe compounds that can interfere with the absorption, metabolism, or utilization of specific vitamins in the body.
