B-2 is which vitamin?

• A. Riboflavin
• B. Thiamin
• C. Niacin
• D. Pantothenic acid

Answer: (A)

B-2 designates riboflavin, a B-complex vitamin. In this numeric naming system, B-2 is the second B vitamin, which is riboflavin. Its active forms, FAD and FMN, act as coenzymes in many oxidation-reduction reactions crucial for energy production from carbs, fats, and proteins. Because these reactions power steps in glycolysis, the TCA cycle, and fatty acid oxidation, riboflavin is essential for turning nutrients into cellular energy. Deficiency can affect mucous membranes and the eyes, and is seen as symptoms like sore lips, mouth cracks, and a smooth, magenta tongue. You’ll find riboflavin in milk, eggs, lean meats, fortified cereals, and green vegetables. The other listed vitamins correspond to different numbers in the B-complex (thiamin is B1, niacin is B3, pantothenic acid is B5), which is why B-2 points to riboflavin.
