Kombucha is a raw beverage that is similar to yogurt in that it contains probiotics that aid digestion. Kombucha is also highly acidic. Because of this, a recommended daily amount for people starting a a Kombucha tea regimen as part of their diet is 4 oz., which can be reduced or added to based on a person's response to the tea.

On the Other: No Clinical Trials of Effects Documented

The health benefits purported to come from Kombucha tea are documented only from personal reports and lab studies that were not conducted on human subjects. The long-term effects of consuming Komucha tea have not been clinically documented. Because of the lack of clinical trials, the Mayo Clinic advises avoiding Kombucha tea until further research is conducted. Herbalists and natural food stores tend to advise that a consumer purchase only Komucha that has been brewed and pasteurized in stable conditions by an FDA-regulated company.

Bottom Line

Because of the disagreements between clinical doctors and brewers of Kombucha, it is best to either avoid consuming the drink, or begin with the recommended 4 oz. per day. Due to the presence of probiotics and the acidity of the drink, consuming large amounts can lead to heartburn and other digestive issues. Introduce Komucha into a personal diet slowly before increasing consumption amounts.
