antivitamins
Nutrient absorption inhibitors
Antivitamins are substances that interfere with the absorption, metabolism, or function of vitamins in the body.
They may work by blocking vitamin uptake, destroying vitamins chemically, or competing for the same biological pathways.
Some antivitamins occur naturally in foods, while others are synthetic compounds used in research or medicine.
Certain raw fish contain antivitamins that break down thiamine.
The term also applies to drugs designed to counteract specific vitamin effects in treating disease.
