Product name:

Vitamin B2

It also called riboflavin, is one of the B vitamins. When the human body lacks vitamin B2, it will affect the body’s biological oxidation and cause metabolic disorders.

Description

Riboflavin is a yellow or orange-yellow, crystalline powder. It is very slightly soluble in water, practically insoluble in ethanol (96 per cent). Solutions deteriorate on exposure to light, especially in the presence of alkali.It shows polymorphism

Application

It also known as riboflavin, is a water-soluble vitamin that cannot be synthesized by the human body and must be supplied by food. It is indispensable for the maintenance of normal physiological functions and metabolism of the human body. Vitamin B2 participates in the normal growth of cells, promotes wound healing, strengthens nails and hair, is also an important component of coenzymes, participates in the synthesis and metabolism of the three major nutrients of carbohydrates, protein and fat, and participates in the formation of red blood cells and the transport of iron. Helps to prevent and treat iron deficiency anemia, and also has a certain hypotensive effect. It is mainly used to prevent and treat angular cheilitis, glossitis, chapped lips, conjunctivitis, scrotum and seborrheic dermatitis caused by vitamin B2 deficiency in clinical practice. .

Features of Vitamin B2:

1. It is easily damaged by light (especially ultraviolet light);

2. It can be destroyed by heating in alkaline solution, so be careful when using it with food or medicine;

3. The body reserves are limited and must be replenished every day.

Riboflavin is mainly used as a medicine, food additive and feed additive. In medicinal applications, it is used in multivitamin or vitamin B2 formulations and as a yellow colorant for sugar coated tablets and capsules. When used as a food additive, it has an effect of strengthening nutrition on the one hand and a yellow coloring agent on the other hand.
