Drinking kombucha every day can offer a range of health benefits. However, over-consuming kombucha can have detrimental effects. Additionally, since kombucha is unpasteurized and has a mix of various bacteria and yeasts, it can lead to opportunist bacteria growing. This can pose a risk of infection in some people, such as those with weakened immune systems. Too much kombucha can also cause bloating or digestive distress. Certain kombucha products can be high in calories and sugar, and most bottles actually contain two servings. If you drink high-calorie versions daily, the drink can contribute to weight gain. Keep in mind that while you can technically make kombucha yourself, contaminated or over-fermented drinks can lead to serious health issues and even death. Buying kombucha online or at a store offers a safer option so you can reap the benefits of this drink.
