A Look at the Popular Sparkling Beverage

Kombucha, the sparkling fermented tea, has become a beloved beverage among the health-conscious community. This beverage originated in China 2,000 years ago. It was traditionally consumed for its health benefits.

Over the centuries, Kombucha has gained popularity worldwide. It has experienced a modern resurgence because of its numerous health benefits, particularly for digestion and gut health. But there's one question that bubbles up often: what about its caffeine content?


Caffeine: A Natural Stimulant

Caffeine is a natural substance found in coffee, tea, cacao plants, and some soft drinks. It is a renowned alertness booster and features heavily in our daily lives. Caffeine works by stimulating the central nervous system.

It helps to improve focus and reduce fatigue. In fact, over half of all American adults consume more than 300 mg of caffeine every day. To give you a snapshot of what this looks like, here's the typical caffeine content in some common items:

A cup of brewed coffee: 96 mg

A cup of decaffeinated coffee: 2 mg

A cup of tea: 47 mg

A can of regular cola: 22 mg

A can of energy drink: 29 mg

    Kombucha: A Balance of Energy and Calm

    Kombucha is brewed using tea, such as green, black, white, or oolong. As a result, it naturally contains caffeine. However, the caffeine content in Kombucha is relatively minimal.

    It averages around just 15 mg per serving. This amount is barely noticeable even to those sensitive to caffeine. This balance is achieved through the fermentation process.

    Yeast and bacteria naturally consume the caffeine during fermentation. The longer the fermentation, the lower the caffeine content. This property of Kombucha makes it a fantastic option for those looking to reduce their daily caffeine intake. It still provides a little bit of energy.

    Unlike coffee, which can raise anxiety levels, tea – and by extension, Kombucha – has a calming effect on the drinker. The amino acid L-theanine is responsible for this effect. It works against caffeine's stimulative effects. As a result, you experience a calming effect 30-40 minutes after ingestion.
