General Description
Vitamin B2 80% feed grade Introduction

Riboflavin is one of the most widely distributed water-soluble vitamins. The above synonyms, lactoflavin and ovoflavin, as well as the terms hepatoflavin, verdoflavin and uroflavin, indicate the source from which the vitamin was originally isolated, i.e. milk, eggs, liver, plants and urine. The term “flavin” originates from the latin word “flavus” referring to the yellow colour of this vitamin. The fluorescent riboflavin is also part of the vitamin B-complex. In the body, riboflavin occurs primarily as an integral component of the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD).
