GNC Vitamin B2 100mg Supplement, Essential for Metabolism of Fats, Carbohydrates and Proteins, 100 Tablets

Benefits of Riboflavin

Riboflavin, also known as vitamin B2, contributes to normal energy-yielding metabolism—a key function that helps convert food into usable energy. This B vitamin also supports the maintenance of normal red blood cells, protects cells from oxidative stress, and contributes to the normal functioning of the nervous system. Additionally, it helps maintain normal skin and mucous membranes. These health claims are authorised by the European Food Safety Authority (EFSA) and are accepted under UK law.

What Is Riboflavin (Vitamin B2)?

Riboflavin is a water-soluble vitamin that acts as a precursor to the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes are essential for the electron transport chain, where they play a vital role in the metabolism of carbohydrates, fats, and proteins. Beyond energy production, riboflavin also functions as an antioxidant, helping to protect cells from oxidative stress. While dietary sources include dairy products, eggs, and leafy green vegetables, supplementation can help fill nutritional gaps.

Who Should Consider a Riboflavin Supplement?

Although most individuals obtain enough riboflavin through their diet, certain groups may benefit from supplementation. Those following restrictive diets—such as vegans or individuals avoiding dairy—may have lower intakes. Athletes and people with high physical demands may need extra support for energy metabolism. Additionally, individuals with digestive conditions that impair nutrient absorption might consider supplementation. It is always advisable to consult a health care professional before starting any supplement regimen.
