A relaxation drink is a non-alcoholic beverage containing calming ingredients normally found in nature. It is a functional beverage which serves to calm a person but unlike other calming beverages such as tea, relaxation drinks almost universally contain more than one active ingredient. Relaxation drinks may be served chilled and carbonated. Others have now been introduced in shot-form. Relaxation drinks are formulated to help reduce stress, anxiety, improve focus, and promote better sleep. Relaxation drinks can be considered the anti-energy drink and have found a niche alongside energy drinks. Some relaxation shots, particularly those with L-theanine, have been known to be used alongside coffee as a way to counter some of the jittery-feeling caffeine can produce.
