According to this Egyptian study, vitamin D is an essential micronutrient in treating viral hepatitis C infections. The study involved 66 children diagnosed with hepatitis C and 28 healthy children. All participants received conventional therapy, with 33 patients additionally receiving a vitamin D supplement. Several parameters were measured to determine the effectiveness of the treatment. The study showed that vitamin D supplementation led to a significantly better immune response, which is important to decrease the risk of viral (hepatitis C) infections. Furthermore, a high frequency of vitamin D deficiency was observed among the infected children. More details can be found in the study.
