Riboflavin

Riboflavin, also known as vitamin B2, is a water-soluble vitamin that plays a crucial role in maintaining overall health. It is an essential nutrient that must be obtained through the diet as the human body does not produce it on its own.

Functions of Riboflavin

Riboflavin is involved in various important functions in the body, including:

• Energy production: Riboflavin is a key component of two coenzymes, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which play a vital role in the energy production pathways of the body.
• Antioxidant activity: It helps to protect cells from oxidative damage by participating in the antioxidant defense system.
• Growth and development: Riboflavin is important for normal growth, reproduction, and overall development.

Sources of Riboflavin

Riboflavin is found in a variety of foods, including:

• Dairy products
• Meat, poultry, and fish
• Eggs
• Green leafy vegetables
• Whole grains

Riboflavin Deficiency

Deficiency of riboflavin can lead to a condition known as ariboflavinosis, which is characterized by symptoms such as sore throat, redness and swelling of the lining of the mouth and throat, cracks or sores on the outsides of the lips (chapped lips), and inflammation and redness of the tongue (magenta tongue). Severe deficiency can also lead to anemia and other health problems.
