Children grow and develop rapidly and have high metabolism. If not paid attention, they are more likely to lack vitamin B2. Vitamin B2 can promote the normal production of skin and hair, and also promotes development. Lack of vitamin B2 will affect the absorption, storage and circulation of iron in the body, causing iron deficiency anemia and affecting the baby's growth and development.

2. The role of vitamin B2 in pregnant women

Since vitamin B2 can promote development and cell regeneration, it promotes fetal development. Women who are pregnant, breastfeeding, or taking birth control pills need more vitamin B2. During pregnancy, 1.6 mg is needed, and during breastfeeding, 1.8 mg is needed for the first 6 months and 1.7 mg for the next 6 months.

Functions of Vitamin B2:

1. It participates in biological oxidation and energy metabolism in the body and is related to the metabolism of carbohydrates, proteins, nucleic acids and fats. It can improve the body's utilization of protein, promote growth and development, and maintain the integrity of the skin and cell membranes. It has the function of protecting the skin hair follicle mucosa and sebaceous glands.

2. It participates in the growth and metabolism of cells and is an essential nutrient for the metabolism and repair of body tissues, such as strengthening liver function and regulating the secretion of adrenaline.

4. Related to the body's iron absorption, storage and mobilization.

5. It also has antioxidant activity, which may be related to flavin enzyme-glutathione reductase.
