Question: what is the difference between kefir and kombucha?
Answer: Although kefir and kombucha both contain healthful microbes, kefir is a richer source of lactic acid bacteria (LAB). So you could think of kefir as a drinkable probiotic supplement, and kombucha as more of a digestive aid. Another big difference is that kombucha typically has caffeine, since it's made from tea.
