According to an analysis by the research team, early signs of liver damage were somewhat more common than normal in the participants, who were all women, with one difference in the genotype.
On average, women with the high-risk UGT1A4 genotype saw the enzyme that indicates liver stress rise by nearly 80 percent after taking a green tea supplement for nine months.
