Blueberry and vitamin C as antioxidants

Vitamin C is antioxidative and can modify the actions of genes. Blueberry was studied to see if it possibly worked in a similar way ⁽¹⁾ . In this study, the participants consumed vitamin C or blueberry juice. Lab tests were conducted to look at urine and specific DNA sites. The results showed that urinary levels of 8-OHdG were reduced by blueberry rather than by vitamin C. The methylation of MTHFR was decreased in blueberry consumers. The authors conclude that blueberry juice shows similar anti-oxidative or anti-premutagenic activity to vitamin C and the potential as a methylation inhibitor for the MTHFR and DNMT1.
