“Probiotics” is a term you hear all over the place these days. Yogurts, juices, smoothies, vitamins—everyone’s on the probiotics train.

But what do they actually do?

Kombucha is a probiotic, which means it’s filled with millions of tiny bacteria and organisms that are designed to replenish and rebalance natural good bacteria in your body. Obviously, antibiotics kill bacteria, and with the continual reliance on antibiotics, nutritionists fear that we’re killing the good bacteria as well.

University of Connecticut dermatologist Meagan McCusker is a fan of probiotics, using them to alleviate “a wide variety of conditions including acne and psoriasis”.

McCusker says, “Probiotics can impact just about everything in the body. They really can’t and shouldn’t be overlooked when it comes to overall health maintenance.”

Kombucha is one of the most widely-used sources of probiotics—which goes to show how important kombucha can be to a healthy diet.
