Tea

Tea is widely thought to be good for your health, but research shows it may be especially good for your liver. Drinking 10 cups of green tea per day was linked to better blood markers of liver health in Japanese research. Drinking high-antioxidant green tea for 12 weeks boosted liver enzyme levels and may also help lower oxidative stress and fat deposits in the liver, according to a smaller study including people with nonalcoholic fatty liver disease (NAFLD). Green tea drinkers were also less likely to get liver cancer, according to another study. People who drank four or more cups per day had the lowest risk.

A number of mouse and rat studies have also shown that black and green tea extracts are beneficial. In one mouse research, for example, black tea extract reversed many of the harmful effects of a high-fat diet on the liver while also improving blood markers of liver function. However, some people, particularly those with liver problems, should be cautious about using green tea supplements. This is because there have been multiple cases of liver damage related to the use of green tea extract supplements.
