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

Benefits of Riboflavin

Riboflavin, or vitamin B2, is a key nutrient that contributes to normal energy-yielding metabolism, making it a valuable ally for anyone with an active lifestyle or increased energy needs. It also supports the maintenance of normal red blood cells and helps protect cells from oxidative stress. Additionally, riboflavin contributes to the normal functioning of the nervous system and the maintenance of normal skin and mucous membranes. These claims are supported by the European Food Safety Authority and are consistent with TGA guidelines.

Who Should Consider a Riboflavin Supplement?

While most people get enough riboflavin from their diet, certain groups may benefit from a supplement. If you follow a restrictive diet (e.g., vegan, dairy-free), you might have lower intake. Athletes and those with high physical demands may need extra riboflavin for energy metabolism. People with digestive conditions that affect nutrient absorption might also consider supplementation. Always consult your healthcare professional before starting any new supplement.

What Is Riboflavin (Vitamin B2)?

Riboflavin is a water-soluble vitamin that plays a vital role in energy production. As a precursor to the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), it is involved in the metabolism of carbohydrates, fats, and proteins. These coenzymes are essential for the electron transport chain, helping convert food into usable energy. Riboflavin also acts as an antioxidant, protecting cells from oxidative stress. While found in foods like dairy, eggs, and leafy greens, supplementation can help fill dietary gaps.

How to Choose the Right Riboflavin Supplement

When selecting a riboflavin supplement, consider the dosage and form. GNC Vitamin B2 provides 100 mg of riboflavin per serving, a common and effective dose.

Recommended Dosage and Safety

The recommended dietary intake (RDI) for riboflavin is around 1.1–1.3 mg per day for adults, but higher doses (such as 100 mg) are commonly used for targeted support. The tolerable upper intake level has not been established due to low toxicity; excess is excreted in urine, causing a harmless bright yellow colour. Always follow the serving size on the label. This product provides 100 mg per tablet, with 100 tablets per bottle. If you are pregnant, nursing, or taking medication, consult your healthcare provider before use. Always read the label and follow directions for use.
