Kombucha – side effects and contraindications

In moderate amounts kombucha is usually well tolerated, but it is worth knowing the situations where caution is advised.

Possible side effects

When consumed in larger amounts, some people may feel bloating or mild digestive discomfort. Kombucha is also lightly acidic and contains trace amounts of alcohol and caffeine (from tea).

Who should be cautious

Caution is advised for, among others, pregnant and breastfeeding women, children and people with weakened immunity or chronic conditions. In such cases it is best to consult a doctor.

Homemade vs commercial kombucha

Home fermentation can be unpredictable – alcohol content is harder to control and, with hygiene mistakes, mould can appear. Kombucha that is produced and lab-tested is safer in this respect. In tests of Nasza Kombucha no pathogenic bacteria were detected.

How to drink it safely

Start with small servings (100–150 ml), keep it moderate, and store bottles in the fridge.
