NOW Supplements, Vitamin B2 (Riboflavin) 100 mg, Energy Metabolism*, 100 Veg Capsules

Riboflavin (vitamin B2) is a water-soluble vitamin that plays a vital role in converting food into usable energy. Many people in the UK choose to supplement their diet with this essential nutrient, particularly those following vegan or vegetarian lifestyles.

Benefits of Riboflavin

Riboflavin contributes to normal energy-yielding metabolism, making it a popular choice for supporting daily vitality. It also contributes to the normal function of the nervous system and helps maintain normal red blood cells. Additionally, riboflavin aids in protecting cells from oxidative stress, which is important for overall health and healthy ageing.* The 100 mg dose per capsule provides a potent amount to support these functions.

What Is Riboflavin (Vitamin B2)?

Riboflavin, also known as vitamin B2, is a water-soluble vitamin that serves as a key component of two major coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes are essential for the metabolism of carbohydrates, fats, and proteins, playing a critical role in the electron transport chain that converts food into ATP, the body's energy currency. Riboflavin also supports the regeneration of glutathione, one of the body's most important antioxidants, thereby helping protect cells from oxidative stress. While riboflavin is naturally present in foods such as dairy, eggs, and green vegetables, supplementation can help fill dietary gaps, especially for those with increased needs or limited intake.

Who Should Consider Riboflavin Supplementation?

Riboflavin supplementation may be particularly useful for individuals with limited dietary intake of B vitamins, such as vegans, vegetarians, or those avoiding dairy. Athletes and active individuals may also benefit from riboflavin's role in energy metabolism. Older adults and people with digestive conditions that impair nutrient absorption might consider a supplement. As always, it is advisable to consult a health care professional before starting any new supplement regimen.
