Vitamin B2

Riboflavin, also known as Vitamin B2, is an essential water-soluble vitamin required for numerous metabolic and cellular processes. It serves as a precursor for two vital coenzymes—flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD)—which participate in redox reactions central to energy production, detoxification pathways, and antioxidant defense. Riboflavin plays a key role in mitochondrial function, amino acid metabolism, lipid processing, and the activation of other vitamins, including Vitamin B6 and folate. Because the body cannot store significant amounts of Riboflavin, consistent intake through diet or supplementation is necessary. Its involvement in cellular growth, ocular health, and neurological stability highlights its broad physiological importance.

Uses of Riboflavin (Vitamin B2)

Energy Production and Metabolic Support:
Riboflavin is essential for mitochondrial ATP generation through its role in FMN- and FAD-dependent enzyme systems, supporting overall metabolic efficiency.

Antioxidant Defense:
Vitamin B2 contributes to the regeneration of glutathione, one of the body's primary antioxidants, aiding in the protection of cells from oxidative stress.

Migraine Prevention:
High-dose Riboflavin has been widely studied for its ability to support mitochondrial energy metabolism and reduce the frequency and severity of migraines.

Eye Health:
Riboflavin plays an important role in maintaining normal vision and protecting ocular tissues from oxidative damage, with research exploring its relevance in conditions such as cataracts.

Skin and Mucosal Health:
Adequate Riboflavin supports healthy skin, hair, and nails, and helps maintain the integrity of mucous membranes through its role in cellular repair and growth.
