RIBOFLAVIN (B2) (Best Nutrition Products)

RIBOFLAVIN (B2)

 

DESCRIPTION

Riboflavin is yellow in color and thus has been used as a food-coloring agent. As with all B-complex vitamins, it is water-soluble and requires a regular daily intake. Since it is sensitive to light it must be shielded from light exposure. For instance, milk in glass or clear plastic bottles loses most of its vitamin B2 content if exposed to too much light.

Riboflavin forms two essential coenzymes, flavin dinucleotide and flavin mononucleotide, which together are responsible for converting proteins, fats and sugars into substances that the body can use. Riboflavin is important for healthy skin and hair.

DEFICIENCY SYMPTOMS

Inadequate daily intake of riboflavin may contribute to sores, dermatitis, hair loss, and burning, itching, light-sensitive eyes.
