Riboflavin

Riboflavin, also known as vitamin B2, is an essential nutrient that plays a crucial role in the body's energy production. It is a water-soluble vitamin, which means it is not stored in the body and needs to be consumed regularly through the diet. Riboflavin is involved in various cellular processes and is important for maintaining overall health.

Functions of Riboflavin

• Energy Production: Riboflavin is a key component of the electron transport chain, which is involved in the production of adenosine triphosphate (ATP), the body's primary source of energy.
• Antioxidant Activity: Riboflavin acts as an antioxidant, helping to protect cells from damage caused by free radicals.
• Supports Growth and Development: Riboflavin is important for normal growth, red blood cell production, and overall health.
• Metabolism of Other Nutrients: It is involved in the metabolism of carbohydrates, fats, and proteins, helping the body utilize these nutrients effectively.

Sources of Riboflavin

Riboflavin is found in a variety of foods, including:

• Dairy products such as milk, yogurt, and cheese
• Meat, poultry, and fish
• Leafy green vegetables
• Eggs
• Legumes and nuts

Riboflavin Deficiency and Toxicity

A deficiency in 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, and inflammation and redness of the tongue. Severe deficiency can also lead to anemia and neurological symptoms.

On the other hand, riboflavin toxicity is rare, as it is a water-soluble vitamin and excess amounts are usually excreted in the urine. However, high doses of riboflavin supplements may cause yellow discoloration of the urine, but this is harmless and temporary.
