The Herbs of Smoothie Essentials: Taurine


Add a Boost with Energy Blend, featuring Taurine

Taurine[1] is a derivative of cysteine, an amino acid which contains a sulfhydryl group. Taurine is one of the few known naturally occurring sulfonic acids. In the strict sense, it is not an amino acid, as it lacks a carboxyl group,[2] but it is often called one, even in scientific literature.[3][4][5]  It does contain a sulfonate group and may be called an amino sulfonic acid. [6]

Taurine is regularly used as an ingredient in energy drinks, with many containing 1000 mg per serving,[7] and some as much as 2000 mg.[8] A 2003 study by the European Food Safety Authority found no adverse effects for up to 1,000 mg of taurine per kilogram of body weight per day.[9]

A review published in 2008 found no documented reports of negative or positive health effects associated with the amount of taurine used in energy drinks, concluding that “The amounts of guarana, taurine, and ginseng found in popular energy drinks are far
below the amounts expected to deliver either therapeutic benefits or adverse events”.[10]

About Smoothie Essentials - ShelleRae

Welcome! I am ShelleRae and I am very excited you are here. I joined the Smoothie Essentials team about 5 years ago now. Always health conscious and into prevention versus medication it seemed natural when the opportunity came up to take on the creation of this blog and the MatchaGT blog as well. As mother to three and surrogate to many more I've practiced much of what I write on sometimes with great success and other times with a bit less. My friends and family are my test kitchen and my facts are most often from WebMD - they seem to have a fairly accurate and conservative approach. The Smoothie Essentials product is a line of boosts that add functionality to one's daily foods without adding flavor or colors. (except for MatchaGT and green blend) making it easy to "hide" them from the finicky eaters we all know and love. From stirring them into yogurts, smoothies, frappes and even juice drinks it all come out with the original flavor being center star.. My inspiration comes from others who also are striving to live a better life through lifestyle changes. More information is available at or by emailing
