Source Naturals Vitamin B-2 Riboflavin 100 mg – 100 Tablets

Benefits of Riboflavin

Riboflavin (vitamin B-2) contributes to normal energy-yielding metabolism, making it a popular choice for those wanting to maintain steady energy levels throughout the day. It also supports normal red blood cell formation, helps protect cells from oxidative stress, and contributes to the maintenance of normal skin, vision, and nervous system function. The European Food Safety Authority (EFSA) has approved these health claims, reflecting riboflavin’s essential roles in the body.

Source Naturals Vitamin B-2 provides 100 mg of riboflavin per tablet—a potent dose that can help fill dietary gaps. As a water-soluble vitamin, any excess is usually excreted in urine, which may cause a harmless bright yellow discolouration.

Who Should Consider a Riboflavin Supplement?

Individuals with limited dietary intake of riboflavin-rich foods—such as those following vegan or vegetarian diets—may benefit from supplementation. Athletes and active individuals often turn to riboflavin to support energy metabolism during exercise. Some people also take riboflavin under the guidance of a health care professional for targeted nutritional support. As with any supplement, assess your individual needs and consult a health care provider before starting a new regimen.

What Is Riboflavin (Vitamin B-2)?

Riboflavin, also known as vitamin B-2, is a water-soluble vitamin crucial for energy metabolism. It is a key component of two important coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes are essential for converting carbohydrates, fats, and proteins into usable energy at the cellular level. Riboflavin also supports the function of other B vitamins, including vitamin B-6 and niacin, and contributes to normal red blood cell formation and cellular antioxidant protection.

Since the body does not store riboflavin, regular intake through diet or supplementation is necessary. Natural food sources include dairy products, eggs, lean meats, and green leafy vegetables, but many people choose a riboflavin supplement like Source Naturals Vitamin B-2 to ensure consistent daily intake.
