Caffeine water is water that has been infused with the flavors of fresh fruits, vegetables or herbs. It’s sometimes referred to as fruit-infused water or fruit-flavored water.

Because it’s made by infusing flavor, rather than juicing or blending, detox water contains very few calories. That makes it a popular drink for detox regimens like the “lemon detox” or “master cleanse.”

Detox water is also often recommended in weight loss plans, especially in place of high-sugar drinks like sugary soda and fruit juice.
