Features of Vitamin B2 Powder:

  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.

Physiological function and role:

  • Vitamin B2 (riboflavin) is a water-soluble vitamin, which is easy to digest and absorb. The amount excreted will increase or decrease according to the needs of the body and possibly the degree of protein loss. It does not accumulate in the body, so it is often supplemented with food or nutritional supplements.
  • Different from vitamin B1, vitamin B2 Powder is resistant to heat, acid and oxidation. Clinically, vitamin B2 tablets are used to prevent and treat vitamin B2 powder deficiency, such as angular cheilitis, chapped lips, glossitis, scrotum, conjunctivitis, seborrheic dermatitis, etc. It can also be used for the treatment of malnutrition and progressive weight loss caused by total parenteral nutrition and insufficient intake.

Chemical nature:

Yellow to orange-yellow crystalline powder, slightly odor, slightly bitter taste. The melting point is 280°C (decomposition). Easily soluble in alkaline solution and sodium chloride solution, slightly soluble in water, slightly soluble in ethanol, insoluble in ether and chloroform. The aqueous solution is yellow-green, and the saturated aqueous solution is neutral.
It has good heat resistance and acid resistance. It is easily damaged in alkaline solution or irradiated by ultraviolet rays, and it is also unstable to reducing agents. Rats were injected intraperitoneally with LD50560mg/kg and ADI0~0.5mg/kg (FAO/WHO, 1994).


  1. Vitamin B2 Powder is a vitamin that promotes the growth and development of the body and plays an important role in the process of human metabolism. When it is deficient, it is easy to suffer from conjunctivitis, angular cheilitis, glossitis and other diseases. It can also be used as a yellow colorant.
  2. For the treatment of riboflavin deficiency, conjunctivitis, nutritional ulcers, systemic nutritional disorders and other diseases
  3. Biochemical research, photocatalyst for acrylamide gel polymerization, nutrient, clinical drugs belong to the vitamin B family, participate in the metabolism of sugar, fat, and protein in the body, maintain normal visual function, and promote growth. It is clinically used to treat angular cheilitis and glossitis caused by vitamin B2 Powder deficiency.
  4. Riboflavin is found in green vegetables, soybeans, rice, wheat, yeast, liver, heart, and milk. Riboflavin is distributed in various tissues in the body and forms a coenzyme in the body’s replenishing hydrogenation system. It participates in redox reactions and is transmitted. The role of hydrogen atoms.
  5. It is a component of the prosthetic group of yellow enzymes in the body (flavase plays a role of hydrogen transfer in biological redox). When riboflavin is lacking, it will affect biological oxidation and cause metabolic disorders. The lesions caused mostly occur in the mouth, Eyes, external genitalia, such as angular cheilitis, conjunctivitis, scrotum, etc.
