Kombucha Contains Antioxidants.

Antioxidants are substances that fight free radicals, reactive molecules that can damage your cells.
Many scientists believe that antioxidants from foods and beverages are better for your health than antioxidant supplements
Kombucha, especially when made with green tea, appears to have antioxidant effects in your liver.
Rat studies consistently find that drinking kombucha regularly reduces liver toxicity caused by toxic chemicals, in some cases by at least 70%
While no human studies exist on this topic, it does seem like a promising area of research for people with liver disease.
