Synopsis

Rating (out of 5): 3

Vitamin B2, also known as riboflavin, is scientifically recognized for its essential role in hepatic (liver) function, although its direct use as a therapeutic agent for liver diseases is limited. Riboflavin acts as a precursor for flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), which are crucial cofactors in numerous oxidation-reduction (redox) reactions central to cellular metabolism, including those occurring in the liver. The hepatic system relies on these coenzymes for detoxification processes, energy production, and the metabolism of fats, drugs, and bilirubin.

Clinical deficiency of riboflavin can lead to hepatic dysfunction, and studies have shown that riboflavin supplementation can prevent or correct biochemical abnormalities associated with such deficiencies. Furthermore, experimental and some clinical studies suggest that riboflavin may have a protective role against oxidative stress-induced liver injury, as it enhances the antioxidant capacity of hepatocytes. However, the evidence for its use as a specific treatment for liver diseases such as hepatitis, fatty liver disease, or cirrhosis is limited, and it is not considered a primary therapy for such conditions. Most support for riboflavin’s role in liver health comes from its established biochemical necessity rather than robust clinical trials targeting liver-specific outcomes.

In summary, while riboflavin is essential for normal hepatic function and deficiency can adversely affect the liver, its supplementation is primarily justified to correct deficiency states rather than as a targeted therapy for liver disorders.
