What is the function of vitamin B2? Riboflavin or vitamin B2 plays a key role in the production of energy by regulating iron absorption, supporting hormone production in the adrenal glands and enabling the body to make better use of nutrients such as fats, proteins and carbohydrates. In addition to this, it promotes beautiful skin, strong nails and good vision. Moreover, vitamin B2 supports normal growth and development and is crucial for a healthy nervous system and liver health. One of its most important functions is preventing birth defects, akin to vitamins B9 and B12.
Vitamin B2 deficiency symptoms include: photosensitivity (sensitivity to light), watery eyes, itching or burning sensations in and around the eyes, painful inflammation of lips, corners of the mouth and tongue, chapped lips and skin cracks in the corners of the mouth, dry, peeling skin, especially around the nose area, anemia, birth defects, nerve damage and liver problems. Very important: vitamin B2 sustains the functions performed by all the other B-group vitamins.
