Common Effects of Caffeine

6. Improve Liver Health

Caffeine may help reduce fatty liver tissue for those with non-alcoholic fatty liver disease caused by conditions such as obesity. The stimulant works in part by increasing fat metabolism in the liver, and by reducing fatty tissue build up. Caffeine also reduces liver fibrosis risk in those with hepatitis C -- as little as 100 mg of caffeine per day can help reduce this side effect. For those who enjoy cleanses, a caffeine enema (administered under the direction of a health professional) may help cleanse and detoxify the liver.
