Vitamin B2, also known as riboflavin, is a water-soluble vitamin that is part of the B complex group of vitamins. It plays a crucial role in maintaining overall health and well-being.

Functions of Vitamin B2

Vitamin B2 has several important functions in the body, including:

• Energy production: Riboflavin is involved in the conversion of carbohydrates into ATP, the body's primary energy source.

• Cell growth and repair: Riboflavin plays a role in the production of red blood cells and the maintenance of healthy skin, nails, and hair.
• Healthy vision: Riboflavin is important for maintaining good vision and overall eye health.

Deficiency and Toxicity

A deficiency in vitamin B2 can lead to a condition known as ariboflavinosis, which is characterized by symptoms such as sore throat, swollen and cracked lips, and inflammation of the tongue. Severe deficiency can also lead to anemia and neurological symptoms.
