Nutrition Tips
- Check the label for added sugars, as some brands add fruit juice or sweeteners after fermentation.
- Look for 'raw' or 'unpasteurized' versions to ensure the probiotic cultures are still active.
- Be mindful of the serving size; many commercial bottles contain two full servings.
- If you are sensitive to caffeine, note that kombucha contains small amounts from the tea base.
- Avoid shaking the bottle, as the natural carbonation can cause it to overflow when opened.
