“Test-tube studies show that kombucha may suppress the growth of cancer cells,” Healthline says. “How the anti-cancer properties of tea polyphenols work is not well understood. However, it’s thought that the polyphenols block gene mutation and growth of cancer cells while also promoting cancer cell death.” Again, studies are still being done to understand the exact effects.

This is a type of tea, most of which have some level of caffeine in it. But as Kombucha Kamp tells us, drinking a kombucha won’t have the same effect on you as drinking an espresso. “Kombucha is generally considered to have about ⅓ the amount of caffeine as the tea it is made with,” they say. “So, for example, black tea, which might have 30-80mg of caffeine per cup may yield a glass of Kombucha with 10-25mg of caffeine.”

Homemade kombucha may also contain up to 3% alcohol,” Healthline warns. Store-bought kombucha, on the other hand, contains less than 0.5% alcohol.
